persistent postvagotomy diarrhoea are labelled neurotic, but
anxiety they show may be a secondary phenomenon,
rather than due to an underlying psychological
abnormality.*91112
We were disturbed to find patients who had
jost their jobs or had to change them because of diarrhoea.
also found that patients with physical disabilities were
particularly badly affected, even infrequent attacks resulting
in incontinence.
Most surgeons believe that postvagotomy diarrhoea
disappears with time. Many gastric surgery patients
experience a short period of diarrhoea after the operation,
shich settles spontaneously; this may have led to a false
complacency. Our study confirms that postvagotomy
diarrhoea does not disappear with time, and we believe there
is little improvement with time. The prognosis for the
patient in whom this side-effect develops is, therefore, not
good.
Ulcer recurrence is widely regarded as being the ultimate
failure of ulcer surgery, but since the introduction of the
Hj-receptor antagonists this may no longer be true.
Postvagotomy diarrhoea may be more difficult to treat than
ulcer recurrence; many of our panents found standard
treatments ineffective. We are now carrying out a study of
treatments for postvagotomy diarrhoea; nearly all patients
have had relief of diarrhoea with once-daily loperamide (to
be published elsewhere). However, any treatment for this
disorder would be required for the rest of the patient’s life.
40 years ago diarrhoea may have seemed a worthwhile
price to pay for safe and effective ulcer-healing. However,
there are now operations virtually free of functional
sde-effects.1314
" We believe it is difficult to justify' the
continued use of truncal vagotomy and drainage and
conclude that the risk of diarrhoea is sufficient reason to
avoid this type of operation whenever possible.

Drug Evaluation
USELESS DRUGS ARE NOT PLACEBOS:
LESSONS FROM FLUNARIZINE AND
CINNARIZINE
Joan-Ramon Laporte
Dolors Capella
Division of Clinical Pharmacology, Univcrsitat Autonoma de
Barcelona, Barcelona, Spain
A PAPER by Chouza er al1 on extrapyramidal signs and
depression induced by flunarizine raises doubts about the
safety of cinnarizine. Flunarizine, a difluorinated derivative
of cinnarizine, was marketed at the beginning of the 1980s,
12-14 years after cinnarizine.
In certain European countries cinnarizine is widely
prescribed for “chronic cerebrovascular disease”. Within
Europe the prescription of “cerebral vasodilators” is
perhaps greatest in Spain, even though other countries have
a higher proportion of old people in their populations. In
1985 8 million units of preparations containing cinnarizine
were prescribed, and in Spain 5-7% of the population over
the age of 60 may be on long-term cinnarizine. In 1984 the
total value of prescriptions of pharmaceutical products
containing cinnarizine and issued by the Spanish social
security system was 6200 million pesetas (about S43-5
million). By contrast, cinnarizine is not even on the market
in the USA, and in Europe its use varies widely.
It is not surprising, then, that extrapyramidal signs
attributed to cinnarizine were first reported from Spain. In
1985 Marti Masso et al2 described eleven patients aged
65 — 83 in whom parkinsonism developed after treatment
with cinnarizine for from 6 to more than 36 months at daily
doses of 150 mg. Subsequently Marti Masso reported a
double-blind, placebo controlled randomised trial of
cinnarizine 150 mg daily in 20 patients with mildly
incapacitating Parkinson’s disease.3 After 1 month, 4 of the
10 patients in the cinnarizine group had to be withdrawn
from the study because of worsening of their condition;
Webster’s score and other objective scores and indicators
significantly deteriorated in the cinnarizine-treated group.
Data on the pharmacokinetics of cinnarizine are scarce.
Although no information is available for elderly people, it
seems that the drug’s plasma half-life in young volunteers is
about 3 h.4 By contrast, flunarizine has an elimination half
life of 4-19 days and is much more lipophilic,5 suggesting
that it is more likely to accumulate and cause CNS effects.
The main indication for cinnarizine is “cerebral
arteriosclerosis” but randomised trials of cinnarizine have
been inconclusive, mainly because inclusion criteria and
outcome variables have not been well specified.6 Nor is the
evidence for the efficacy' of other drugs used as cerebral
vasodilators convincing.7

prescribe them for every such patient in an irrational way by
spinal reflex prescription rather than by rational drug
prescription.
Why are drugs of this kind available in. important
pharmaceutical markets in Western Europe? Drug
registration authorities evaluating a new product will look at
efficacy and safety. If there is no benefit demonstrated and
the drug carries risks, the benefit/risk ratio is zero, and the
drug should not be on the market, especially if it is to be paid
for with public money through a national health or social
security scheme. The registration-of drugs of no proven
efficacy is potentially dangerous.. Such drugs should be
banned, and national health authorities should adopt clear
criteria for the evaluation of drug efficacy.

Parkinsonism, tardive dyskinesia, akathisia, and depression induced by flunarizine.
Cinnanzine is mainly prescribed to old people with
intellectual impairment and/or focal neurological signs, in
whom extrapyramidal signs may easily be attributed to
spontaneous deterioration rather than drug-induced
parkinsonism. This may be why so few cases were notified
through the spontaneous reporting system that has been
operating in Catalonia since 1983: of 7 adverse drug
reactions attributed to cinnarizine, 5 were extrapyramidal
symptoms. The WHO International Drug Monitoring
Programme’s file in Uppsala contains 3 further repons of
extrapyramidal disorders and tremor associated with
cinnarizine (table) and 6 repons of extrapyramidal disorders
associated with flunarizine. The accompanying table shows
that extrapyramidal symptoms do occur at the
recommended daily flunarizine dose of 10 mg, even in
young patients, contradicting Amery’s points8 about
Chouza’s paper.1
Cinnarizine, flunarizine, and drugs with a similar
spectrum of indications (eg, co-dergdcrine and citicoline)
are used as “mass placebos” in some countries. The
successful marketing of these useless drugs—which are not
even mentioned in most pharmacology textbooks—suggests
that prescribers either accept the claims made by
manufacturers, being unable to conceive that a registered
drug can lack efficacy, or, while sceptical about those claims,
mistakenly believe that a drug without any proven benefit
will at least be safe.
Suloctidil, another “cerebral vasodilator” recommended
for cerebral and peripheral ischaemia, was withdrawn in
1985 because it was found to induce hepatitis, in some cases
fatally. Another dangerous “placebo” withdrawn in 1985
was cyanidanol, promoted as a hepatoprotective agent for
the treatment of hepatitis B and other liver diseases. Cases of
haemolytic anaemia, some fatal, were ascribed to it.
The main side-effect of placebos, however, is not likely to
be uncovered by any drug surveillance system. Misused
placebos may produce the false sensation, among doctors
and patients, that some treatment is being provided when in
fact nothing is being done except delay the diagnosis and
treatment of the disease underlying the patient’s symptoms.

cardiovascular disease is related more closely to systolic than

trial of treatment of mild hypertension2 appears to give some
support to this view. It stated that systolic blood pressure a1

subsequent development of strokes and all cardiovascular
complications, whereas diastolic pressure at entry was less
clearly related to the risk of complications. This conclusion
was certainly incorrect for strokes, as will be shown below»
and may also be incorrect for other cardiovascular
complications.
The MRC report also stated that there was no relation
between systolic or diastolic blood pressure at entry to _
study and the percentage reduction in stroke incidence wi

benefits of treatment were uniform over the range of bk*pressure studied. This conclusion is also incorrect. 1

ated in the body to oxyphenbutazone, and this metab
olite is also available as a drug.
Antipyrine is slowly metabolized by hydroxyla
tion at liver microsomes, with a half-life of about 8
hours. Phenylbutazone and oxyphenbutazone are even
more slowly metabolized and are well reabsorbed by
the renal tubules, resulting in a half-life in excess of 2
days.
Sulfinpyrazone (Anturane), the metabolite of a
compound closely related to phenylbutazone, is a very
useful uricosuric agent.
Pharmacologic Effects
The therapeutic effects are similar to those of
aspirin-ie. these drugs are analgesic, antipyretic, and
anti-inflammatory.
Clinical Uses & Dosages
The pyrazolone drugs exert an antipyretic effect
in some situations in which aspirin is not completely
effective—eg, Hodgkin’s disease with fever unresponsive
to salicylates or chemotherapy. They are probably also
more potent as analgesics and anti-inflammatory agents
in arthritis, bursitis, and thrombophlebitis. There is no
justification for the use of aminopyrine or dipyrone.
A. Antipyrine: Antipyrine can be used orally,
0.3-0.6 gm every 4-6 hours, as an alternative to
aspirin. The volume of distribution of antipyrine or its
metabolite, N-acetyl-4-aminoantipyrine, may also be
used to measure total body water.
B. Phenylbutazone (Butazolidin) and Oxyphen
butazone (Tandearil): Butazolidin, Tandearil, and
Butazolidin Alka are among the 200 drugs most com
monly prescribed by physicians in the USA, suggesting
that they are often used as first treatment drugs rather
than as alternatives to aspirin. Yet the restrictions on
their use and the contraindications and cautions made
a part of the labeling by the manufacturer are so strin-

gent and comprehensive that responsibility for any
adverse result of therapy would probably devolve on
the physician. The drugs should not be used without
reference to the package insert.
The use of these drugs is suggested or permitted
in acute rheumatoid arthritis or spondylitis, osteo
arthritis, psoriatic arthritis, “painful shoulder,’’ acute
superficial thrombophlebitis, and acute gouty arthritis.
The daily dose is stated to be 300-600 mg/day
by the labeling. A more conservative position limits the
daily dose to 200 mg. These drugs should be discon
tinued if no improvement is observed in 4—5 days.
Adverse Reactions
The toxicity of the pyrazolone analgesics restricts
their use.
A. Antipyrine: Antipyrine causes fewer side
effects than aspirin. Unlike aminopyrine, it has rarely
been associated with agranulocytosis. It has caused an
allergic erythematous rash, often about the mouth,
that leaves pigmented areas when it resolves.
B. Agranulocytosis From Aminopyrine and
Dipyrone: The unusually high risk of agranulocytosis
following the use of these 2 analgesics is generally
acknowledged. As is true for many therapeutic agents,
the quantification of the risk is difficult, and the drugs
continue to be used in some countries. Neither of the
drugs was used recently in the USA until dipyrone
reappeared during the period 1960-1964. Imports of
dipyrone rose from none in 1958 to 19,000 lb in 1962.
During the period 1960-1964, 18 cases of agranulo
cytosis associated with the use of dipyrone, one-third
of them fatal, were reported to the AMA registry. How
complete this reporting was cannot be established. The
dipyrone was probably not recognized by the physi
cian as a derivative of aminopyrine, emphasizing the
need to think of drugs in terms of general classes rather
than individual compounds. The use of drugs under
their trade names and the prescribing of proprietary
mixtures without first identifying the ingredients
undoubtedly also led to the misuse.
In the USA. any preparation or mixture contain
ing aminopyrine or dipyrone must now bear a label
warning that the drug may cause agranulocytosis and
that it should be used only when specifically indicated
and when less toxic drugs-eg, salicylates-have proved
ineffective or are not tolerated.
The characteristics of agranulocytosis are dis
cussed in Chapter 6. The reaction is allergic in origin
rather than dose-related and is due to the sudden
peripheral destruction of granulocytes.
C. Phenylbutazone: Phenylbutazone and its
metabolite, oxyphenbutazone, frequently cause side
effects, and serious toxic reactions are frequent enough
that their use should be greatly restricted. Dose-related
toxic effects include sodium retention and edema, dry
mouth, nausea and vomiting, peptic ulceration and
hemorrhage, and rare cases of renal tubular necrosis
and liver necrosis. Allergic reactions include dermatitis,
which may rarely progress to exfoliative dermatitis,
and agranulocytosis.
Phenylbutazone may cause a reversible leukemoid
reaction: of greater concern, however, is the possibility
(not yet well established) that its chronic use may be
associated with a high incidence of acute leukemia.
Administration of phenylbutazone increases the
effects of tolbutamide and warfarin.

nol). Official preparations include tablets (120 and
325 mg) and an elixir and syrup (120 mg/5 ml); a
solution (60 mg/0.6 ml) is also available.
The conventional oral dosage is 325 to 650 mg
every 4 hours for adults and older children. The total
daily dose should not exceed 2.6 g. For young chil
dren. the single dose is 60 to 120 mg. depending
upon age and weight; total daily dosage should not
exceed 1.2 g Acetaminophen should not be admin
istered for more than 10 days or to young children
except upon advice of a physician.
Phenacetin {acetopheneiidiri) is no longer an offi
cial drug. It is too insoluble to be prescribed in
aqueous solution, and is usually administered orally
in powder, capsule, or tablet form. In recent years
it has been employed primarily in analgesic mix
tures. The average single dose for adults is 300 mg:
the total daily dose should not exceed 2.4 g.
Therapeutic Uses. Acetaminophen or
phenacetin is a suitable substitute for aspirin
for its analgesic or antipyretic uses in patients
who are allergic to aspirin or when aspirin
is contraindicated, as in patients with gout
or peptic ulcer. Acetaminophen has some
what less overall toxicity and is preferred
over phenacetin. Neither drug is an effective
antirheumatic agent. An additional minor
convenience of acetaminophen is its avail
ability in a liquid dosage form for oral inges
tion.
Analgesia. For headache, dysmenorrhea, arthral
gia. myalgia, and similar disorders, a therapeutic
dose of acetaminophen or phenacetin may be given
every 3 or 4 hours. Self-medication over a period
of days is not advised. If ordinary' doses are ineffec
tive. larger amounts as a rule do not give relief.
Acetaminophen is definitely less effective than aspi
rin in patients with active rheumatoid arthritis, and
any relief obtained is due to the analgesic effect.
Analgesic combinations containing acetaminophen
and phenacetin are discussed below.
Aniipyresis. The use of acetaminophen or phen
acetin to reduce fever is similar to that of aspirin.
The indications and the rationale for reducing body
temperature are discussed in connection with the
salicylates.
Pyrazolon Derivatives:
Antipyrine and Aminopyrine
Antipyrine {phenacone) and aminopyrine {amido
pyrine) were introduced into medicine in the late
nineteenth century' as antipyretics and subsequently
were also widely used as analgesics and anti-inflam
matory agents. However, clinical use of aminopyrine
was sharply curtailed after its potentially fatal
bone-marrow toxicity was recognized, and anti
pyrine has also lost favor. Both drugs have virtually
disappeared from the therapeutic scene in the
United States, but antipyrine is still employed in
some countries, usually in analgesic mixtures. A
#76 ,
variety of related pyrazolon derivatives have enjoyed
sporadic popularity. The congeneric phenylbutazone
has limited usefulness as an anti-inflammatory agent
{see above).
Chemistry and Pharmacological Properties. Anti
pyrine and aminopyrine are closely related phenylpyrazolon derivatives. Their structural formulas are
as follows:
CH,
I
Antipyrine
Aminopyrine
The pharmacology and toxicology of antipyrine
and aminopyrine have been reviewed by Greenberg
(1950). Randall (1963). and Beaver (1965, 1966). In
both animals and man, the pyrazolon derivatives
exhibit analgesic, antipyretic, and anti-inflammatory
properties similar to those of the salicylates: Neither
antipyrine nor aminopyrine has been subjected to
adequately controlled clinical trial by current stand
ards. However, aminopyrine was considered the su
perior anti-inflammatory agent and equivalent to
aspirin for therapy of acute rheumatic fever. Unlike
salicylate, the pyrazolon derivatives are not organic
acids, are only slightly bound to plasma protein, and
do not have uricosuric properties. They do not cause
gastric irritation or produce the acid-base or meta
bolic effects of salicylate.
Aminopyrine Agranulocytosis. Aminopyrine and
its close congener dipyrone cause a high incidence
of agranulocytosis. This allergic reaction is charac
terized by the presence in the plasma of antibodies
to granulocytes (see Wintrobe, 1969). In rare indi
viduals. instead of frank agranulocytosis, each ad
ministration of aminopyrine produces a sharp fall
in total leukocyte count associated with a severe
chill, spiking fever, headache, and pain in muscles
and joints; the attack is over within a few hours. The
incidence of aminopyrine-induced agranulocytosis
has been variously estimated between 0.01 and
0.86%. The mortality rate has been 20 to 50% (see
Huguley, 1964).
Antipyrine. Reports of agranulocytosis attributed
to antipyrine have been rare. Nevertheless, because
it is closely related to aminopyrine and because it
is not superior to safer drugs, the use of antipyrine
as an analgesic and antipyretic is not recommended.
Whether antipyrine has clinically useful antirheu-

malic properties has never been adequately deter
mined. It is no longer an official drug.
Antipyrine is employed as a pharmacological tool
for measurement of total body water and for assess
ment of hepatic microsomal mixed-function oxidase
activity. Il is rapidly and essentially completely ab

concentration is usually attained in 1 to 2 hours. It
is less than 10% bound to plasma proteins and is
distributed in various tissues in proportion to their
water content. About 30 to 40% of the drug is con
verted to 4-hydroxyantipyrine. This metabolite is
rapidly and almost completely conjugated with glu
curonic, and perhaps sulfuric, acid and excreted in
the urine. Only about 5% of unaltered antipyrine is
eliminated in the urine. Hydroxylation of the side
chain also occurs, but the fate of a significant frac
tion of the drug remains uncertain. The plasma
half-time for the unchanged drug is 7 to 20 hours
(see Brodie and Axelrod. 1950).
Antipyrine causes induction of the hepatic micro
somal enzyme system and modifies the biotransfor
mation of other drugs, including the oral anticoagu
lant agents.
Aminopyrine and Dipyrone. “Over-the-counter’
sale of aminopyrine in the United States has been
prohibited since 1938. and federal regulations re
quire that preparations of aminopyrine and dipy
rone bear a warning on the labels stating that the
drug may cause fatal agranulocytosis.
Although it is an excellent antipyretic, analgesic,
and anti-inflammatory agent, and despite its advan
tages over salicylate, aminopyrine ordinarily should
not be employed because of the danger of agranulo
cytosis. In some cases of prolonged intractable fever.
as in Hodgkin’s disease and periarteritis nodosa,
aminopyrine is capable of controlling the disability
and may be justified. Dipyrone, the methanesul
fonate derivative of aminopyrine, has similar phar
macological and toxicological properties, including
the potential to cause fatal agranulocytosis. It differs
only in being more soluble and available for paren
teral administration.
If used at all in the treatment of intractable fever,
aminopyrine or dipyrone should be employed only
after safer drugs and other measures have proven
ineffective, and only with proper supervision and
monitoring. Administration of dipyrone with chlor
promazine can result in serious hypothermia, and
such use is contraindicated. Dipyrone can aggravate
a bleeding tendency or prothrombin deficiency.
Salicylamide
Salicylamide, the amide of salicylic acid, is no
longer an official drug. Its effects in man are not
reliable, and its use is not recommended. The small
doses included in “over-the-counter” analgesic and
sedative mixtures are probably ineffective.
Although not metabolized to salicylate in the
body, salicylamide has antipyretic, analgesic, and
anti-inflammatory effects similar to those of salicy
late. It also has sedative and hypotensive effects.
However, the drug is very rapidly inactivated during
[Chap. 17]
absorption and the initial circulation through the
liver. Concentrations of active drug in the systemic
circulation are markedly influenced by the dosage
form, and they are disproportionately low after low
doses. Salicylamide may inhibit ths metabolism of
other drugs by the liver.
Analgesic Combinations and
Mixtures
Aspirin, acetaminophen, and phenacetin
are frequently administered with each other
and a variety of other drugs, including
caffeine, sedatives, and the opioid analgesics.
Concurrent administration of an opioid and
an analgesic-antipyretic, such as codeine and
aspirin, has a valid role in analgesic medica
tion. However, none of the mixtures of
analgesic-antipyretics, including the tradi
tional aspirin-phenacetin-caffeine combina
tion, has been shown to provide significant
advantage over medication with aspirin
alone.
Irrational analgesic mixtures, such as those
with a hazardous component or presumed
active ingredients that are in fact inert, can
be expected to disappear from the thera
peutic scene when the assessment of “overthe-counter” medications currently being
conducted by the FDA is completed and the
recommendations of its panel are imple
mented.
Combined Opioid and Analgesic-Antipyretic Medi
cation. In most controlled clinical trials, codeine,
65 mg. has been found to add significantly to the
analgesic effect of aspirin, 650 mg. The combined
codeine-aspirin effect can be duplicated by larger
doses of codeine alone, but considerations of toxicity
and abuse favor restricting the dosage of the opioid.
Thus, combined codeine-aspirin analgesia is justified
if aspirin alone in full dosage is ineffective. Gastro
intestinal and central side effects typical of the opi
oids are the price for the increased analgesia pro
vided by this multiple-drug therapy. Parenteral
opioids are still required for relief of severe pain.
In adequate dosage, other orally effective opioids
add similarly to the analgesic effect of aspirin. In
general, a dose of an opioid that given alone pro
vides uncertain analgesia adds only equivocally to
the analgesic effect of aspirin. Although it is likely
that an effective dose of an opioid adds to the anal
gesic effect of acetaminophen as it does to that of
aspirin, clinical documentation is required. The
usual arguments for and against the use of fixeddose mixtures versus concurrent but separate ad
ministration of the components apply to combined
opioid and analgesic-antipyretic medication (see
Chapter 1).

Mean Steady-State Concentration =
Dosing Rate
Clearance
Clearance is measured in units of vol
ume per unit of time, and describes in
quantitative terms the capacity of a
given individual to biotransform or
eliminate a given drug. Drug clearance
is usually accomplished by hepatic bio
transformation, renal excretion, or a
combination of the two. Thus, under
usual circumstances, the steady-state
concentration of a particular drug in a
given individual is directly propor
tional to the dosing rate (with the
exception of a few drugs with saturable
or nonlinear kinetics, such as salicy
late, phenytoin, and alcohol). Among
different individuals, however, any giv
en dosing rate is likely to produce wide
variations in steady-state concentra
tion, attributable to large interindividual differences in clearance (Fig 1). A
number of identifiable factors can alter
the clearance of drugs, such as age,
gender, body habitus, disease states,
cigarette smoking, and drug interac
tions.2" However, substantial unex
plained individual variation in drug
clearance is commonly observed even
among healthy, drug-free persons of
the same sex and within a narrow age
range.1" Therefore, dosage may not be a
good predictor of steady-state concen
tration.
“Therapeutic range” and “therapeu
tic index” are two concepts used to
quantitate the relationships of serum
concentration to efficacy and safety,
respectively. Some drugs have a welldefined therapeutic range. When the
steady-state concentration falls within
this range, the likelihood of clinically
effective and nontoxic therapy is maxi
mized. Direct measurement of the
serum concentration allows appro
priate upward or downward titration
of dosage in the individual patient, to
attain the desired level. Therapeutic
ranges, however, are not absolute (Fig
2). Levels at the “low” therapeutic end
have a significant likelihood of being
clinically ineffective, whereas levels at
the high therapeutic end have a signifi
cant likelihood of causing toxic effects.
In experimental pharmacology, “thera
peutic index” is defined as the ratio of
the median lethal dose to the median
effective dose. In clinical medicine,
however, therapeutic index is usually
estimated as the ratio of the highest
potentially therapeutic concentration
divided by the lowest potentially thera
peutic concentration (Fig 2). Some
drugs (such as gentamicin, digoxin, and
lithium) have a narrow therapeutic
range and therefore a low therapeutic
index. For such drugs, one can antici
pate considerable overlap among inef
fective, effective, and possibly toxic
concentrations, thereby increasing the
importance of serum level monitoring.
Serum drug concentrations may still
be of considerable value even when a
therapeutic range has not been defi
nitely established. Consider a patient
with no apparent clinical response to
drug therapy despite seemingly ade
quate dosage. A measured steady-state
concentration that appropriately re
flects the dosage rate suggests that the
patient may actually be a “nonrespond
er." If, however, the measured level is
very low or undetectable, this suggests
that the patient either is not taking the
medication (noncompliance) or has un
usually high metabolic clearance. An
other example is the patient with a
sign or symptom (such as loss of
appetite during digitalis therapy) that
could be attributable either to an
adverse drug reaction or to the
underlying disease itself." In this case,
a high serum drug level suggests that
the medication might be responsible
for the adverse effect; a low serum
level, on the other hand, could indicate
that the underlying disease, or some
other factor, explains the reaction.
Drug concentrations frequently are
measured for medicolegal reasons. In
cases of deliberate or accidental drug
overdosage, verification of the particu
lar substances ingested, and their con
centrations in serum, may have impor
tant therapeutic and forensic value.
“Screening” of current and prospective
employees for the presence of “illicit
drugs” is becoming increasingly com
mon, although these tests are usually
done on samples of urine.12

Finally, the availability of methods
for measurement of drug concentra
tions provides the impetus for clini
cians to increase their expertise and
understanding of pharmacologic and
pharmacokinetic principles of drug
therapy. Enhanced awareness of dose
concentration relationships, and fac
tors influencing these relationships,
may lead to an overall improvement in
the quality of drug treatment.13
drug distribution and
ACCESS TO ITS RECEPTOR
When a drug is given by an extravascular route of administration (orally,
intramuscularly, rectally, subcuta
neously, sublingually, transdermally,
2228
JAMA. Oct 24 31
1986-Vol 256. No 16
etc), or even by intravenous injection,
the entire administered dose does not
have immediate and complete access to
its receptor site mediating pharmaco
logic activity (Fig 3). After intravenous
injection, the entire dose reaches the
systemic circulation and by definition
has 100% bioavailability. However, the
drug is distributed not only to the
tissue where it is active, but also to a
number of other sites (Fig 4). Further
more, once the drug has reached the
systemic circulation, it also encounters
serum or plasma proteins. Drugs are
bound to proteins to varying de
grees.1415 The principal binding pro
teins are albumin and cq-acid glycopro
tein. The affinity of a drug for serum
protein limits its freedom to diffuse
across cell membranes, hence further
limiting its accessibility to the receptor
site.
When a drug is administered by an
extravascular route, it reaches the sys
temic circulation indirectly, often
yielding less than 100% bioavailabili
ty."' Oral bioavailability of drugs in
tablet and capsule form can be influ
enced by incomplete absorption due to
incomplete dissolution, which in turn
depends on packaging and drug parti
cle size. Oral solutions overcome the
dissolution problem. Other factors that
can influence oral bioavailability in
clude changes in gastrointestinal mo
tility, gastric and intestinal pH, mal
absorption
syndromes,
and
the
coadministration of foods and drugs
(especially
antacids,
antidiarrheal
agents, and chelating agents).
After absorption of the drug from
the gastrointestinal tract, systemic bio
availability may be reduced because of
metabolic transformation in the gut
wall, or by extraction from the portal
circulation during the “first pass”
through the liver. This is the case for
certain drugs characterized by high
hepatic clearance, including proprano
lol, lidocaine, tricyclic antidepressants,
opiate analgesics, neuroleptics, hydral
azine, nitroglycerin, verapamil, and
prednisone.1.
Incomplete bioavailability after in
tramuscular injection is also possible.
This has been attributed to poor drug
solubility at physiologic pH and precip
itation at the injection site after
administration of chlordiazepoxide, di
goxin, phenylbutazone, phenytoin, and
quinidine.1"
A number of recent studies have
evaluated drug absorption after sublin
gual or buccal administration.111'21 In
principle, this route of administration
delivers the drug directly into the
systemic circulation, bypassing both
the gastrointestinal tract, where some
drugs are degraded or metabolized, and
the portal circulation and consequent
first-pass hepatic extraction. For most
drugs evaluated to date, bioavailability
after sublingual dosage is equivalent to
or greater than that after oral admin
istration. A similar principle holds for
rectal drug administration, since ap
proximately 50% of the hemorrhoidal
circulation empties into the systemic
rather than the portal venous system.21
Finally, the transdermal23 or pulmo
nary route can be used to administer
some drugs.
For all these reasons, drug concen
trations in blood, serum, or plasma
often reflect pharmacologic action
more closely than administered dosage
alone.

FACTORS INFLUENCING
INTERPRETATION OF
SERUM DRUG CONCENTRATIONS
Total vs Free Serum
Concentrations
Although only the unbound or free
drug can passively cross cell mem
branes and interact with receptors,
free drug levels nonetheless are still
not routinely monitored. This is partly
because their measurement is techni
cally more difficult to perform than
that of total levels. Fortunately, for
most drugs, the ratio of free to total
serum concentration (free fraction!

drug concentrations. In general, it
takes four times the drug’s half-life at
a constant dosing rate for the steady
state condition to be more than 90%
attained. Similarly, an increase or
decrease in dosage will require the
same time interval to reach the new
steady-state level (Fig 6). After initiat
ing therapy with long half-life drugs, a
considerable length of time may be
required for steady state to be attained
(Fig 7). Therefore, sampling before the
attainment of the actual steady-state
condition may lead to premature dos
age adjustments. This is of particular
importance for drugs such as theophyl

such as aminoglycosides or lithium.
Unfortunately, however, the time of
peak concentration can seldom be pre
dicted with certainty.
If the dosage interval is not regular,
or if the drug is taken intermittently,
then the best time to sample is not
necessarily so obvious, since there is no

dosing is useful to minimize transient
effects due to high peak levels that
some people find objectionable, such as
sedation and drowsiness from certain
psychotropic drugs.35 On the other
hand, dosing schedules that require
very frequent dosing are inconvenient,
and may be associated with reduced
patient compliance.
Certain sustained-release formula
tions of drugs have been designed to
prolong drug action after each dose,
thereby allowing less frequent dosing.
If the rate of drug entry into the
systemic circulation precisely mimics a
fixed-rate infusion, then the serum
drug level will not fluctuate. Although
this is not an attainable ideal, some
sustained-release preparations do in
fact allow infrequent dosing, with only

small fluctuations in serum drug con
centrations?'
At steady state, each discrete drug
dose is followed by an “absorptive”
phase, during which serum concentra
tions exceed the mean. Transient side
effects may be associated with the
absorptive peak. After peak concentra
tions are reached, the serum level then
falls as distribution and clearance pre
dominate. Just before the next dose,
levels are at a minimum during the
“trough” phase. Sampling shortly after
a dose, during the absorptive phase, is
not recommended for evaluation of
therapeutic efficacy since the measured
level does not necessarily correspond to
the peak. Furthermore, even if the
peak level was found to be in the
therapeutic dosing range, this would
not ensure therapeutic levels through
out the entire dosage interval. The
optimal time to sample for evaluation
of efficacy is just before the time of
dosing (Fig 9), to ensure that the
minimum drug level falls with the
therapeutic range. If the trough level is
found to be subtherapeutic, the clini
cian may elect to give smaller doses
more frequently while maintaining the
same total dose per 24 hours (Fig 8).
This change would reduce the interdose
fluctuation and possibly bring the
trough level to within the therapeutic
range. Measurement of peak serum
concentrations after an individual dose
may be of value when clinicians wish to
evaluate potential drug side effects
coinciding with peak concentrations.
Knowledge of both peak and trough
concentrations may be desirable for
Artefacts due to Collection Tubes
The Vacutainer brand of blood col
lection tubes is reported to contain
TRIS (2-butoxyethyl) phosphate, a
plasticizing agent. Blood samples
drawn into these tubes can give spu
riously low serum drug levels when the
serum is analyzed for imipramine,
alprenolol, propranolol, lidocaine, and
quinidine.33 The mechanism for the
lowering of serum levels appears to
involve displacement of drugs from
0,-acid glycoprotein (but not from
albumin) by TRIS (2-butoxyethyl)
phosphate. This in vitro phenomenon
results in an increase in unbound drug,
which quickly diffuses into and equili
brates with the red blood cells present
in the tube. Thus, when the serum is
aspirated after centrifugation, the re
sultant serum drug level is spuriously
low. However, the whole blood level is
unchanged. Any drug that is extensive
ly bound to aracid glycoprotein is
likely to be influenced by this collection
artefact.
Analytic Methodology
Knowledge of the methodology used
by a laboratory in analyzing serum for
drug levels may be of critical impor
tance for the clinician in interpreting
the results. Ideally, an assay procedure
for a particular drug should (1) resolve
compounds of similar structure, such
as the parent drug and its metabolic
products or other substances present in
the serum (specificity); (2) consistently
conform to accepted standards for
accuracy and replicability for the range
of concentrations encountered clini
cally; and (3) be sensitive enough to
quantitate levels well below the thera
peutic range. In addition, the need for
cost containment must always be con
sidered. Procedurally straightforward
analytic methods that can be auto
mated are generally less expensive and
therefore preferred. However, such
procedures, although less costly, may
not provide adequate specificity, accu
racy, replicability, and sensitivity'.
More complex and often more expen
sive analytic methods may be needed
,to provide meaningful serum concen
tration data.

In principle, they rely on the interac
tion between a drug acting as an
antigen and an antibody to it. Since
most drugs are nonimmunogenic, they
first must be conjugated by a bridge or
linkage group to a substance of high
molecular weight, such as a protein. In
this conjugated mode, the drug behaves
like a hapten and is used to immunize
an animal. Antibodies may be gener
ated against the drug if the conjuga
tion bridge or linkage keeps the drug
sufficiently far from the larger protein
molecule. The necessity for an antibody
to seek out a hapten creates the inher
ent variability in specificity provided
by immunoassays. Some antibodies
may show cross-reactivity with metab
olites and congeners of the drug of
interest, thereby rendering the anti
bodies relatively nonspecific.”
In the radioimmunoassay (RIA),
drug present in a serum sample com
petes with a radioisotope-labeled
ligand for antibody binding sites. The
RIA procedures are stated to be very
sensitive, but require the use of
radioactive material and are costly.
Enzyme immunoassays substitute an

.JAMA. Oct 24/31. 1986—Vol 256, No
enzymatic label for a radioactive one.
The inhibition of labeled enzyme activi
ty by antibody is the basis for the very
popular enzyme-multiplied immunoas
say technique. This technique is
claimed to be procedurally straightfor
ward and inexpensive, but is considera
bly less sensitive than RIA and can
have variable specificity, particularly
when applied to screening for drugs of
abuse in urine.12,10,11 Most nonisotopic
immunoassay labels are inactivated by
antibody; hence, they do not require
the separation of bound from free
labeled ligand as in RIA.
Chromatography is a method of sep
arating mixtures of substances based
on their physicochemical characteris
tics, so that one or more of those
substances may be specifically de
tected. The principal methods used in
drug measurement are gas-liquid chro
matography (GLC)12 and high-pressure
liquid chromatography (HPLC).13 Se
rum, or a concentrated extract thereof,
is injected onto a column through
which flows a mobile phase. For GLC,
the mobile phase is a purified gas such
as helium, nitrogen, or argon. For
HPLC, the mobile phase contains mix
tures of an aqueous buffer and an
organic solvent such as acetonitrile or
methanol. Separation of the serum
components by the mobile phase is
influenced by interactions with the
column’s stationary phase. Actual sep
arations are based on lipophilicity,
polarity, molecular size, temperature,
and boiling point (for GLC). The HPLC
separations may be further refined by
varying the pH and polarity of the
mobile phase. Often it is possible to
detect and quantitate the parent drug
and some or all of its important metab
olites simultaneously.
For some applications, a mass spec
trometer is coupled to a chromato
graph’s effluent and thereby acts as
the detector. This combination pro
vides the “gold standard" in specificity
and sensitivity in drug analysis. How
ever, mass spectroscopy is expensive
and requires complex instrumentation
as well as highly trained personnel.
When the drug mixture is well sepa
rated chromatographically, other less
complex detection systems usually suf
fice. In GLC, the most commonly used
detectors are flame ionization, nitrogen-phosphorus, and electron capture.
Flame ionization will respond to all
organic compounds. Nitrogen-phosphorus has enhanced response to nitro
gen- and phosphorus-containing com
pounds, and electron capture responds
to drug-containing electronegative sub
stituents such as halogens, nitrates, and
conjugated carbonyls. The sensitivity
of nitrogen-phosphorus and electron
capture is in the subparts-per-billion
range; that of flame ionization is on
the order of parts per million. Highpressure liquid chromatography most
commonly utilizes spectrophotometry ’,
fluorescence, or electrochemistry for
the detection and quantitation of drugs
after chromatographic separation. Flu
orescence detection is applicable to
molecules with rigid polyaromatic
structures or extensive conjugation
having the property of absorbing light
and then emitting.it at a lower wave
length. Electrochemical detection is
employed for the recognition of easily
oxidized or reduced groups such as
phenols, indoles, and secondary and
tertiary nitrogens. In favorable cases,
fluorescence and electrochemical detec
tion can extend sensitivity two orders
of magnitude beyond the spectrophoto
metric range.
The above information can be
extremely useful to clinicians in inter
preting serum drug concentration re
ports. Consider, for example, a “nondetectable” serum concentration report
This must be interpreted in light of the
lower limits of sensitivity of the partic
ular assay technique. If the assay
technique has a high degree of sensitiv
ity, a reported zero level may actually
mean that there is no drug present in
serum. Conversely, it may imply that
clinically important amounts of drug
may be present in serum, but the assay
is not sufficiently sensitive to quanti
tate levels in this range. At the other
extreme, laboratories may report very
high serum drug concentrations in 1
patient taking “usual doses” and hay
ing no manifestations of toxicity. This
might be attributable to the use of»
very nonspecific assay technique that
quantitates not only the drug in que*tion but also its metabolic products, *

Parent Drugs and
Active Metabolites
Many drugs used in clinical practice
are biotransfornied into other com
pounds that themselves are pharmaco
logically active.4145 When evaluating
the therapeutic effects of such drugs,
clinicians must integrate the relative
contributions of all active substances
present in serum. Physicians should be
knowledgeable of the metabolism of
the drugs they prescribe, and analytic
laboratories should automatically mea
sure concentrations of parent drug and
active metabolites. Consider, for exam
ple, a patient taking imipramine, which
is biotransformed to the active metabo
lite desipramine. Clinicians requesting
a serum imipramine concentration
should expect, and laboratories should
provide, simultaneous concentrations
of both imipramine and desipramine
present in the sample. In a few years,
this problem may become further com-
plicated by the appreciation of other
active metabolites of imipramine, such
as hydroxyimipramine and hydroxydesipramine."’
SUMMARY
The simple act of ordering a serum
drug level does not guarantee that the
information will be meaningful or use
ful. The interpretation of serum con
centrations can be profoundly influ
enced by such factors as the timing of
the sample, the patient’s clinical state,
the drug’s pharmacokinetics and me
tabolism, and the tube type and analyt
ic methodology used. The likelihood of
obtaining clinically meaningful and
useful results can be maximized when
these factors are taken into account.

DOES PERITONITIS IN THE UPPER ABDOMEN
CAUSE PAIN IN THE TIP OF THE SHOULDER?
DANGEROUS AND INAPPROPRIATE DRUGS
Competition between manufacturers in flourishing
economic systems is said to benefit the consumer by way of
cheaper and better products. This may be true when, say,
television sets are being sold in sophisticated markets where
the consumer has a good idea of what- he wants and needs.
The argument crumbles when the.bpyer has an imperfect
understanding of the virtues and vices of what is on offer. In
Western industrialised countries the ordinary citizen
perceives, if somewhat dimly, what medicines can offer, but
is nevertheless prey to plausible suggestions. He is therefore
likely to take on trust that, because some aspects of health
screening are useful in some people, there may be wider
benefits to all—thus fostering a growing and often virtueless
industry in wellperson screening. He will accept advice to
buy branded products when the non-proprietary versions
differ not at all, except in price, and he will assume that,
because substances are labelled as health foods, herbal
remedies, and homoeopathic remedies that they are indeed
valuable. Some protection is available through the activities
of drug regulatory and consumer advisory bodies, but there
remains a wide and perhaps growing trend towards the
promotion of costly practices which vary from the mildly
deceptive to the frankly fraudulent.
Underdeveloped countries are beset by greater
difficulties. They are ill placed to afford expensive but
useless health care products, let alone the frankly dangerous.
They have unsophisticated consumers and tend to have
poorly developed regulatory and advisory systems. Against
this background it is hardly surprising that pharmaceutical
manufacturers, both international and indigenous, have
indulged in practices which would be obviously
unacceptable in Western countries. The World Health
Organisation essential drugs list is a straightforward attempt
to draw attention to the virtues of a limited range of generally
cheap drugs, but it has so far failed to secure the widespread
acceptance it deserves.
Health Action International has lately issued a
compendium1 of leaflets which detail the depressingly
widespread tendency to peddle dangerous and
inappropriate drugs in poor countries. It draws attention,

A wise student soon learns that he can save himself effort
by coupling understanding with fact. This is a great help
where embryology, anatomy, and clinical signs can be linked.
Pain—in particular referred pain—lends itself to this
approach. We soon learn, for example, that colic from the
ureter radiates to the groin and does not cross the midline
because each side of the urinary tract has a multisegmental
unilateral origin. We are therefore tempted, having found
such relations, to apply the process in reverse. Since the heart
and diaphragm originate from the cervical septum
intermedium, which descends to the centre and lower part of
the chest, we would expect referred pain in the area supplied
by the cervical nerves. Coronary occlusion frequently causes
arm pain, so we expect irritation of the diaphragm to do the
same. Nowadays we see basal pleurisy infrequently, but in
the past it was common, caused by pneumococcal and
tuberculous infection. As we expect, there is shoulder tip pain
with such disease.
We could assume that if irritation of one side of the
diaphragm gives shoulder tip pain, the same symptom would
arise from inflammation (peritonitis) on the abdominal side.
This is what is commonly taught. However, only part of the
diaphragm has a cervical origin. The rest is costal in
derivation. The central or cervical area is not greatly exposed
to the main peritoneal cavity. Most of all the right side is
protected by the liver, which also has a large bare area. The
greater part of the left side is isolated from the main cavity by
the spleen, stomach, liver, and the reflections of the lesser sac.
The most exposed part is that which is costal in origin, even
when the peritoneal cavity contains gas and acid. Therefore,
the pain is seldom referred to the shoulder tip: instead it is
referred to the lower chest area. When the patient with a
perforated ulcer is asked to sit up, pain between the scapulae
is almost invariably present, whereas pain in the shoulder is
very rare.
Thus if a patient has pain suggestive of a diaphragmatic
lesion and the pain is referred to the tip of the shoulder, we
should direct our attention more to the chest and its contents
than to the abdomen.

unsupportable actions it catalogues this tone is
understandable. The recommendations are generally clear,
entirely acceptable, and obviously necessary (rchydration
therapy before the use of antidiarrhoeals, ban oxyquinolines,
cold cures do not work), but they could sometimes be better
framed. Thus the recommendations for action on butazones
are really part of an extended (and appropriate) diatribe, but
lose force by being buried in the text; and the
recommendations about contraceptives stem not from drug
problems but problems of society (the second of HAI’s
recommendations here is to improve the status of women).
Virtuous as the Health Action International pack may be,
a more important approach might be directed at the vested
interests, not necessarily within the pharmaceutical
industry, which perpetuate such a sorry state of affairs.

In England Now
The great debate of the moment is, of course, whether or not the
Health Service is sufficiently funded. The Government—that is to
say, the Prime Minister—speaking ex cathedra, assures us, in tones
that brook no argument, that it is better funded than ever before in
its history.
But those of us at the business end, both as providers and
consumers, are not convinced. If money is adequate, why are wards
being closed? Why are nurses’ homes being sold off, on the wholly
fallacious theory that, in future, any girl wishing to take up nursing
can jolly wrell do it in her home town^ Why, as in our hospital, does a
secretary, when requiring a new pen, have to go to the Unit Admin
Office, between 9.30 and 10 on a Tuesday, carrying the old one with
her to effect an exchange? Why ... oh, why go on? We are told,
firmly, that things are fine and all of these problems must be but
figments of our imagination. Can we not see that the Emperor is
wearing the most beautiful suit of clothes?
No, we cannot However, let us, in all charity, assume that the
figures do show that, in real terms, more money is going into the
NHS, and ask where it is going, as patient care plummets. An awful
lot must go into administration. Now, fair enough, administrators
are necessary, but is not the very' substantial tail now’ wagging the
weak and emaciated dog? Look at the money that is spent (w’asted?)
every few years in “reorganisation”. Salmon. Area and District
Management Teams. Scrap the Area tier. Now Griffiths—down
with consensus, bring back despotism. Yet all of these schemes have
cost vast sums of money and certainly all have led to a proliferation
of the numbers of people not actually involved in patient care. The
latest changes are no exception. Every general manager must have
deputies; every chief must have his persona] Admiral Byng who can
be shot on his own quarterdeck if things go wrong “pour encourager
les autres”. Of course, we are told, this reorganisation is the answer,
which will streamline the National Health Service and maximise
resources into patient care. I have heard this before—several times.
This time it is the importation of fresh managerial blood which will
do the trick. This, perhaps, is the last of the old quaint English
eccentricities—that if you want something done, you appoint
someone with no knowledge of the subject. Provided a man was a
gentleman—and preferably an officer as well—he could be a
magistrate and know no law, rule an empire, and know nothing of
the culture he ruled. Many of the new managers are ex-servicemen.
Is running a Health district really no different from running a small
RAF station or a minor ordnance depot? Are the accounts really the
same as keeping an eye on the junior officers’ mess bills?
We all heaved a sigh of relief when, at long last, Donald
passed his finals. In those far-off days, every medical year had
one—a student who always struggled on the brink of
dissolution. No examination was ever passed at the first attempt
and it was usually only at the third or fourth try that success
finally rewarded effort. Indeed, with Donald, success was
achieved mostly because we all rallied round to tutor him. After
graduation he disappeared into an overworked practice in one
of our underdeveloped areas.
Our paths failed to cross until I met him again at our 30th year
reunion. He was impeccably dressed in a Savile Row suit and
his Rolls Royce was parked rather ostentatiously outside the
hotel entrance. He gave three cases of champagne to the
chairman to help with the jollification.
During the cocktails, conversation, and canapes phase we fell
to talking. His Harley Street practice was doing nicely, thank
you very much. He attributed his success to the fact that he had
discovered a new disease, and this had made him popular. I
lifted my eyebrows, inquiringly. Yes, he said, it consisted of
headache, backache, mild depression, and an urge to talk to
someone for about 15 minutes or so. It particularly affected
middle-aged women. But what had really made his name was a
feature never before described. Indeed, when he told his
patients of his finding, they were horrified that all the other
doctors had missed it. “You know those funny sounds you hear
through the stethoscope when you take a blood pressure?” he
said. I agreed cautiously. “Well,” continued Donald. “I found
in every’ case, without exception, that the diastolic blood
pressure was always higher than the systolic.”
Am I alone in thinking that this Christian name business is getting
out of hand? I know that we arc, in the NHS, supposed to be one
happy family, but do we have to go around using first names all of
the time as pan of the pretence?
I have always written my clinical letters to “Dear Dr Bloggs”,
never “Dear Jim”. At first, all the Bloggses used to be older than me,
and I would have felt it rude and presumptuous to be familiar. Now
the tables are turned; most of the Bloggses are but veritable children,
and I do not wish them to be familiar, so I retain the formality.
Now everyone expects instant intimacy. Junior administrators,
still with marked post-auricular dampness, take it for granted they
can use my Christian name, and are offended by the careful “Mr” I
employ for them. Even nursing officers seem to consider it their
right to call consultants by their first names, and to be so addressed
in return. It is, I suppose, all part of the quaint fallacy that, to work
together, we must all be chums (“and you shall call me Eric”),
whereas it is easier to work with people about whom you are neutral
and with whom you maintain a polite formality.
It all reaches its heights (or depths) with patients. I have for years
been fighting a losing battle against the practice of automatically
calling patients by their first names. The retired professional lady,
called “Miss Jones” all her life, does not want, I am sure, to have
chits of girls calling her “Molly”. Then there is the old man, always
called “Mr Smith” by his wife in public, or “Dad” in the family
circle, who suddenly finds complete strangers calling him “Jack”.
Mind, I have to concede that the use of first names is, marginally,
better than “Gran” or “Pops” or whatever other totally demeaning
soubriquet the young happen to favour for the elderly at the time.
But how much nicer would “Miss Jones” or “Mr Smith” be—more
dignified, more respecting of individuality, all those things to which
modern-day nurses pay lip service but ignore in practice.

Agranulocytosis Induced by Dipyrone,
a Hazardous Antipyretic and Analgesic
Charles M. Huguley, Jr., MD, Atlanta
N INCREASING NUMBER of reports of agran.ulocytosis associated with dipyrone are being
received by the American Medical Association’s
Registry on Adverse Reactions. Between 1955 and
1959 only ten cases of leukopenia associated with
this drug had been reported to the Registry from
the United States, and none of these were in chil
dren. Since 1960, reports of 18 cases have been re
ceived, seven of them in children. Thirty-six percent
of these patients have died. Since it is probable that
many more cases of agranulocytosis occur than are
reported to the Registry, these data are a cause for
concern.
During the same period there has been a striking
increase in the use of dipyrone. Much of the dipy
rone used in this country is imported; domestic
production and sales figures are not available, but

creased from none in 1958, to 220 lb in 1959; 7,164
lb in 1960; 39,790 lb in 1961; and 18,879 lb in 1962.
This increase in the use of dipyrone is puzzling,
since the drug has the same pharmacological effects
and therapeutic indications as aminopyrine, of
which it is a derivative. Aminopyrine, on the other
hand, does not seem to be in frequent use in this
country, and only seven cases of leukopenia associ

AGRANULOCYTOSIS—HUGULEY
In 1934, the Council on Drugs condemned the in
discriminate use of aminopyrine and criticized the
confusing and uninformative names used for prepa
rations containing the drug. As shown by the partial
list in the Table, a comparable situation exists today
with the derivative, dipyrone.
Pharmacology.—These two drugs are almost iden
tical pharmacologically; sulfonation of aminopyrine
to dipyrone renders it more soluble without affect
ing other properties. Both compounds are demethyl
ated to 4-aminoantipyrine, a portion of which is
then acetylated to 4-acetylaminoantipyrine. Neither
of the parent compounds, antipyrine and 4-amino
antipyrine, has been used to any great extent sys
temically in this country and, although antipyrine is
used topically, there have been no reports of agran
ulocytosis attributable to it. The structural for
mulae of these parent compounds are shown in
Fig 3 and 4.
Efficacy.—Although it has been shown in animal
studies that aminopyrine is an effective analgesic
and antipyretic,1411 there are no reports of double
blind, randomized studies comparing either amino
pyrine or dipyrone with any other drugs to deter
mine their relative effectiveness. Nevertheless, there
is little question of the efficacy of these two drugs as
analgesics and antipyretics.’ Wolff and associates
studied the effect of a variety of analgesic drugs on
the pain threshold in man. The effect of equal doses
of aminopyrine and aspirin was identical.'’ For
many years, however, the lack of use of either
aminopyrine or dipyrone in this country has indi
cated that American physicians have obviously felt
that they had no advantages over salicylates and
similar drugs that would justify the danger atten
dant upon their use.
There have been only four articles in recent years
in the American literature advocating the use of
aminopyrine.’ '7"1 Of these, the report by Cardon
et al presents the most persuasive argument for the
occasional use of aminopyrine.’ Aminopyrine af
forded complete relief in six patients who had
severe febrile illnesses in which the major sympto
matology was referable to fever. Spear reported
that of 74 patients with Hodgkin’s disease whose
charts he reviewed, 62 had fever.17 He states that
aspirin "given in a haphazard fashion’’ failed to
relieve the fever in 31 of 35 patients but that in 18
of these patients aminopyrine, given every six hours,
afforded effective relief. One can, of course, specu
late on what might have been accomplished by the
regular administration of aspirin or another rela
tively safe antipyretic. Another article recommends
the use of aminopyrine for the treatment of diabetes
insipidus, although it is not clear why the authors
felt that the antidiuretic hormone was not accept
able therapy, since they had demonstrated its effec
tiveness in their patient as proof of the diagnosis.'8
The only other article advocating the use of amino
pyrine presents no data.1’
JAMA, Sept 21, 1964
The unfortunate aspect of these articles is that
the authors all minimize the incidence of agranulo
cytosis and state that the hazards of aminopyrine
have been overemphasized. These statements have
been refuted by Wintrobe and by Trimble,7' and
it is appropriate to consider just how dangerous
these drugs are.
Incidence of Agranulocytosis
Aminopyrine.—In a review article, Discombe cites
the use of aminopyrine in four series of over 200
patients each, in which nearly all patients received
the drug for at least 14 days and most for a much
longer period.3 The incidence of agranulocytosis
ranged from 0% to 0.91%. The total number of pa
tients in the four series was 1,272 and the total
number of cases of agranulocytosis was 11, or 0.86%.
Of the II patients who developed agranulocytosis,
eight died (0.63%). Even if we add to these the 103
patients of Simon and Metz,77 the 18 of Spear,17
and the 6 of Cardon et al,’ none of whom developed
a blood dyscrasia, we will have a total of 11 cases
and eight deaths in 1,399 patients, an incidence of
0.79% and a mortality rate of 0.57%. These are the
only figures that a diligent search of the literature
has revealed among patients who have received the
drug regularly over a period of at least two weeks
and who were observed during the period of ad
ministration.
Discombe3 estimates that, in countries in which
aminopyrine was freely available, there probably
were two to five cases of agranulocytosis per 1
million inhabitants per year. It is very likely that in
that era a large number of cases of acute sore throat
secondary to agranulocytosis were not diagnosed as
such and, even among those in whom the diagnosis
was established, many cases may not have been
reported. Dameshek and Colmes6 estimated that
there was one case of agranulocytosis for every
10,000 prescriptions of aminopyrine. This does not
take into consideration the fact that the disease ap
parently requires a period of time for sensitization
to occur, so that patients who received only a few
doses would not be expected to have a reactionMoreover, those who used the drug for a long pc*
riod very likely had prescriptions refilled, so that
10,000 prescriptions may represent less than 10,000
patients.
Dipyrone.—Aminopyrine and dipyrone are, 50
similar that there is no reason to suspect that they
are not equally likely to produce agranulocytoseThe first case of agranulocytosis associated 'V1
dipyrone was reported in 1935.' Later, a human
volunteer known to be sensitive to aminopyrine ***

have been reported to the Registry. An additional
14 cases have appeared in the foreign literature. Of
this total of 51 patients, 19 (37%) died.
Some of these case reports illustrate the cross
reactions between dipyrone and aminopyrine. One
patient previously had agranulocytosis after receiv
ing aminopyrine.” Of several patients who had re
covered from dipyrone-related agranulocytosis, one
developed full-blown agranulocytosis within 24
hours after being given 0.6 gm of aminopyrine; one
reacted to a test dose of dipyrone itself”; and one
was shown to have a positive skin test, serum leuko
cyte agglutinins, and positive response to a test dose
with both dipyrone and aminopyrine. Three other
patients were tested with dipyrone for the presence
of leukocyte agglutinins, and the results in two were
positive.25 27
Comment
This recent increase in the use of dipyrone and in
cases of agranulocytosis and death resulting from it
must give us pause, particularly since so many chil
dren are among the victims. We must consider
whether there are any special advantages offered by
941
these drugs that warrant the risk of a serious and
possibly fatal reaction. From the articles urging the
use of dipyrone, it is obvious that those who pre
scribe it are chiefly taking advantage of its anti
pyretic effect. However, there are several effective
antipyretics on the market in addition to aspirin,
and there are also physical measures that may be
used to reduce acute pyrexia, particularly in chil
dren. The rather limited use of dipyrone and amino
pyrine in this country in the past suggests that most
physicians find these other drugs satisfactory, and
there is a widespread belief that there are practi
cally no circumstances in which aminopyrine or
dipyrone is indicated.4,2“ Admittedly, reports indi
cate that some patients with fever respond well to
aminopyrine after they fail to respond to aspirin,5 '7
but these would seem to be too rare to justify use
before a thorough trial of other drugs.
The question facing the medical profession is
whether the continued use of these drugs is justi
fied. Seven deaths, three of them in children, have
been attributed to dipyrone in the US in the past
four years. Have this many lives been saved through
use of the drug?

scientifically. These include
acupuncture and hypnosis which are
being currently featured. In some
cases, alternate therapy can be
dangerous as was demonstrated by
the use of Laetrile.
Pain and Fever, one or both these
symptoms, account for the majority
of presenting complaints to a
physician. Viewed with a casual air,
they are often vital clues to reach a
diagnosis. Therefore, an update of
the pathology and management of
pain and fever is much called for.
can cure may also harm.
Unfortunately emotional overtones
cloud rational judgement. 'Weighing
Risks’, an article in this issue,
suggests a rational approach to this
problem. It examines the balance
between risk and benefit with relation
to not only drugs but also everyday
events.
Symptomatic treatment always vies
with specific therapy. Yet its value in
terms of relief obtained and
improvement in well-being is the
cornerstone of successful medicine.
Patients expect to be rid of
uncomfortable symptoms, even
before the disease runs its natural
course,- thus promoting the physician
to reach for the first analgesic and/or
antipyretic agent. In satiating the
demand for relief, there is sometimes
a subtle suspicion of an
accompanying risk.
One result of the fear that has been
induced by emotionally charged
allegations of drug risks is the revival
of fringe medicine — homeopathy,
herbalism, hypnosis, acupuncture
and iridiology. But alternate therapy
or fringe medicine has yet to prove
its worth under scientifically
controlled clinical trials.' The-recent
report of the Board of the Science
Working Party of the British Medical
Association on Alternate therapy
found no reason why it should not be
assessed by the same scientific
principles that are applied to
conventional practice.2
However, running parallel to this
demand for relief of unpleasant
sensations is the concern that what

On the other hand, the close control
of pharmological and toxicological
testing has reduced the chances of a
drug being released for general use.3
Great strides have been made in the
field of adverse drug reporting and in
statistical methods of evaluating
risks. These have permitted a
scientific approach to determine the
true incidence rates of rare side

effects. As an example, two studies
O
designed to determine the incidence
of rare adverse drug reactions,
presented at the III World Conference
of Clinical Pharmacology and
Therapeutics held in Stockholm last
year have been reported. These
studies along with Weighing Risks
have resulted in Weighing Risks — A
Case in Point an article which
demonstrates the need to cultivate a
cautious and balanced attitude not
only towards the ‘victim oriented'
press reporting but also to apparent
‘scientific studies' which could be
pivotal in decision making. A
pertinent example relevant to this
issue of the Medical Bulletin is the
repeatedly quoted and outdated
estimate of the risk of aminopyrine
induced agranulocytosis by
Discombe and Huguely — despite
the fact that it was based on
evaluation of data from different
sources which are not comparable
and which were arbitarily collected.4
The results of these studies are in
conflict with all practical experience4
and have been disproved by the
recent International Study on
Agranulocytosis and Aplastic
Anaemia reported in the October
issue of the Journal of the American
Medical Association.5

Pain — A Review
As different as one person is to
another,so is the experience of pain
felt by each individual'; so, too, the
resulting pattern of behaviour and
reaction. Pain is a personal, private
and subjective experience it is a hurt
we feel; this underlies the affective
element which is an integral part of
the pain experience.
But different though each person
may be to another, at another level
they are alike; likewise pain has its
commonly shared characteristics. It
is these characteristics, — the
emotionally neutral ones — that will
be discussed here. The affective
element is no less important but will
be dealt with briefly. In many cases
of chronic pain and, rarely, acute
pain the affective element can
drastically change the pain
experience as in the famous and
often cited example of soldiers on
the battlefield who do not feel injuries
when they occur2; or the less known
one of walking barefoot over hot
coals during neurolinguistic
programming3. In these cases a
strong emotion suppresses pain. On
the other hand,a once brave and
courageous person can be so
affected by chronic pain to become
a cranky, complaining, miserable
and irrational creature.
Pain is considered a protective
mechanism of the body which allows
recognition at a conscious level that
a harmful or potentially harmful
stimulus or situation threatens the
structural and functional integrity of
the body — and if uncontrolled,
subsequently of the mind too. It
allows the person to respond to
these threats with a battery of
responses that will result in
protection from,or avoidance of
these stimuli. These responses
range from a verbal 'ouch' to a
conscious decision to visit a doctor
and include postural adjustments,
avoidance of movements, affective.
autonomic and other physiological
and neurological responses. A
description of pain based on any
one of these responses does not
give a comprehensive view of the
pain phenomenon, and stresses the
need to take all the aspects of pain
into consideration while determining
treatment. To not do so can be
detrimental to the patient: for
example, a patient who has been
diagnosed as having 'psychogenic
pain' (on the erroneous belief that he
has a painless pain) is treated
exclusively by psychiatry.'
On the other hand,if it is decided that
the pain is ‘physical’, one somatic
treatment after another, each more
desperate than the earlier, is
prescribed.
Pain should be approached,
considered and treated at all levels.
This is all the more so in the cases of
chronic pain as pain is a sensation
which does not exhibit the
phenomenon of adaptation and can
therefore have many adverse effects
on a patients life.
Pain can be conveniently viewed as
acute or chronic; the difference being
that in acute pain the sufferer can
usually give a clear description of the
location, severity, fluctuation, mode
of onset and factors that aggravate
or relieve it. This sort of pain usually
responds well to analgesics. On the
other hand, descriptions of chronic
pain are comparatively vague and
are influenced by cultural, religious
and psychological factors; this pain
does not respond as well to
analgesics.
Furthermore,objective signs such as
pallor, tachycardia, mydriasis.
hypertension, sweating — (signs of
autonomic nervous system
hyperactivity) — are seen in acute
pain-and present a clinical picture of
anxiety? Chronic pain tends to cause
disturbances in work, sleep, social,
sexual and other functions and thus
comes close to a clinical picture of
depression? The point at which acute.
pain — which serves the purpose of
warning that something is wrong —
becomes chronic varies,but is
arbitrarily taken as six months.5
Pain is often experienced before
other signs and symptoms of the
disease occur. It is thus essential for
the physician to understand well the
sensory supply of the body surface
and also the viscera as well as the
differences in the quality and types of
pain to reach a diagnosis. The
sensory supply of the body surface is
illustrated in Figure 1. A given spinal
segment also supplies a visceral

area with autonomic nerve fibres.
The important nerves for
intrathoracic viscera are the first to
the fourth thoracic,while for the upper
abdominal,the sixth to the eighth.
Superficial pain has two components
— a quick pricking sensation,
followed by a burning pain a few
seconds later — this constitutes the
double response of Lewis. Visceral
and deep musculoskeletal pain have
the quality of cramping or aching but
can occasionally be sharp or
burning. While superficial pain can
be localized to a single sensory
segment both deep musculoskeletal
and visceral' pain cannot be localized
to closer than 2 to 3 segments and
are often indistinguishable from each
other; for example,the pain of renal
colic may resemble that of a tear in
the lumbar muscle in location and
quality. Likewise,a tear in a muscle in
the chest may resemble that of
angina.
Due to a greater cerebral
representation in the sensory supply
of the integumen as opposed to that
of the viscera, pain in the latter is
often referred superficially. The
location of the referred pain on the
3
points to arterial pulsation as a
cause. Sharp, stabbing and
recurrent pains usually result
from disease of nerve roots or
sensory ganglion. What is
important is to determine whether
the pain is steady or fluctuating.
A steady pain is found in peptic
ulcer, angina pectoris, gall
bladder colic and renal colic. With
the latter two. the word colic is
misleading as the pain is actually
steady6. True colicky pain
suggests the obstruction of a
hollow viscus6.

surface of the body lies in the
dermatome of the spinal segment
which supplies the affected viscera.
Table shows the sensory segments
to which pain in certain viscera are
reffered to. The paucity of pain
representation in the viscera is
eloquently described in the
accompanying extract.
Harvey (1628, see 1962 ed.)
remarked upon the absence of
sensation in the exposed heart of
Viscount Montgomery. Harvey
records, “I carried the young man to
the King (Charles I) that His Majesty
might with his own eyes behold this
wonderful case; that, in a man alive
and well, he might, without detriment
to the individual, observe the
movement of the heart, and with his
proper hand even touch the
ventricles as they contracted. And
His Most Excellent Majesty, as well
as myself, acknowledged that the
heart was without the sense of touch;
for the youth never knew when we
touched his heart ...”7
Occasionally an aberrant referral of
pain occurs. Pain spreads to areas .
next to those that are affected. This
happens due to pre-existing disease
in adjacent areas which have already
caused a partial depolarization in the
neurones supplying these areas;
which then easily become
depolarized by the new disease6. A
person with cervical arthritis might
thus have the pain of myocardial
infarction referred to the neck region.
Clinical Approach:
In dealing with a problem of pain a
detailed history, general physical
examination, neurological
4
examination and perhaps a
psychiatric evaluation are required.
The importance of a detailed account
from the patient on the history of the
pain cannot be stressed adequately
because it is on this information that
the physician can arrive at a
reasonable conclusion regarding the
cause of the pain.
History:
The following inquiries should be
made:
a)
The location of the pain: This
helps to identify the cord
segment involved'and will limit
the diagnostic possibilities to be
considered.
b)
Exacerbating and Relieving
factors: These pointers are
valuable clues to the possible
mechanisms producing pain.
Pain on swallowing focuses
attention to the oesophagus;
back pain which worsens on
sitting or walking suggests disc
disease, while similar pain
aggravated on lying down.
suggests intraspinal disease.
c)
Mode of onset: Pain reaching its
'full' intensity almost immediately
indicates rupture o.f a tissue as in
dissection of the aorta or in
perforation of a peptic ulcer
Time of occurrence: Pain that
occurs several hours after a meal
and which is relieved by food
suggests the action of acid on the
stomach or duodenal mucosa.
Joint pains'that are more severe
with the first movements after
prolonged rest point to arthritis.
e)
Quality of pain: A throbbing pain
d)
f)
Duration: Anginal pain rarely lasts
more than 15 minutes; in contrast
the pain of myocardial infarction
persists longer.
g)
Severity: Determining the severity
of pain based on the persons
judgement is difficult as people
differ in their tolerance to pain.
Pain should be taken to be
severe if it interferes with the
person's work, sleep or social
activities, is accompanied by
physiological signs or requires
therapeutic intervention.
After a systematic interrogation,
measures which reproduce and
relieve pain should be attempted,as
these, apart from confirming the pain
mechanism, convince the patient
that the doctor understands his
problem.
A psychiatric evaluation along with
the inquiry regarding pain should be
done and signs and symptoms of
depression,such as loss of sleep and
appetite, loss of weight, reduction in
social pain and sexual functions
should be noted especially in chronic
pain.
General Physical Examination:
Begin with the site of pain. Examine
the area for any swelling, deformity
and redness. Palpate for tenderness.
check if temperature of area is
raised.
Joints should be taken through the
full range of movement,noting if the
character of the pain changes.
Nerve trunks should be palpated and

abnormalities, one can assume that
the pain is due tc it.but one cannot
rule out the involvement of the
nervous system in the absence of
such abnormalities.
Laboratory tests and other
investigations are determined and
depend entirely on the possible
cause of the pain.
Management:
An important consideration in pain
management is the possibility that
the cause of pain can be eliminated.
Even if one cannot eliminate the
cause,it is possible to reduce pain
more easily if one is aware of the
origins of the discomfort.
Before considering the management
of pain, the pathway of the pain
sensation and the sites of drug
action should be clearly understood.
Figure 2 illustrates this in brief.
Though the main site of action of the
non-narcotic drugs is by the
inhibition of prostaglandins at the
periphery, somejike analgin,also
have a potent central nervous
system effect.
Paracetamol also possesses a CNS
effect,but its mode of action is
undead1 as it has a weak effect on
prostaglandin synthesis.
The side-effects of the non-narcotic
analgesics are also related to their
inhibition of prostaglandin synthesis;
the most common being the ability to
induce gastric or intestinal bleeding
and ulceration'-1. Other side-effects
include renal toxicity, hepatotoxicity
and allergic reactions. In cases of
hepatic disease or overdose of the
drug, paracetamol is potentially fatal.
Though rare, aspirin usage has been
significantly linked with the fatal
Reye’s Syndrome in children with
concurrent viral infections and
should therefore be avoided in
children. The use of this drug is now
banned in India for children under 12
years of age.
Though these drugs are classified as
effective in pain of low to moderate
intensity,this is not altogether true. In
cases of post-operative pain.nonnarcotic drugs are preferred to
narcotic analgesics.
What is, however., notable about the
long list of non-narcotic drugs is not
so much the difference between
them but the striking similarities in
drug action. Some of these drugs
such as aspirin and analgin also
possess anti-inflammatory and
antipyretic actions. Rather than
attempt to memorize the long list of
drugs and their minor differences,
the physician should familiarise
himself with a few preparations.
The weak narcotic analgesics may
be used for mild to moderate pain,but
as there is a slight euphorant effect,
they should not be used for long
periods of time as they carry the
potential for addiction. In these
cases the patient’s mental status
should be well assessed.
The potent narcotics have their use
in severe visceral pain, severe pain
due to trauma including post
operative care and the pain of
advanced malignant disease.
Fig.2 : Pain pathway and sites of action of drugs
Mention must be made here of the
recently recognised
neurotransmitters,encephalins and
endorphinsjn pain relief. These
endogenous peptides have a
profound and long-lasting analgesic
effect and have been found in
various parts of the nervous system,
namely,the periaqueductal gray
matter, medullary raphe, the neurons
in the dorsal horn of the spinal cord,
in the thalamus and the
frontotemporal cortex. Their action
is blocked by the opiate antagonist
naloxone and they are therefore part
of a natural endogenous analgesic
system. They also probably play a
role in the analgesic response to
opiates.
5
Another major inhibitory pathway in
the pons appears to inhibit the
nociceptive responses of the dorsal
horn neurons.
Guidelines:
The management of pain should
observe the following guidelines.
a)
b)
Identification of the cause —
Certain conditions can be treated
by particular agents, for example.
the pain of angina pectoris
responds to glyceral trinitrate;
trigeminal neuralgia and the
lightning pains of tabes dorsalis
to carbamezepine. Bone pain
from metastatic prostate cancer
responds to stilbestrol and post
herpetic neuralgia to
carbamazepine along with a
tricyclic antidepresant.
Begin with the simplest method
(or drug) but with early treatment
and adequate dosing. There is
strong evidence that if pain is not
treated for an extended period of
time, abnormal excitatory states
arise in the CNS so that treatment
which would have earlier relieved
the pain does so no longer.
Oral drugs are preferable to
parenteral drugs as they are
drugs with few side-effects and
low addictive liability.
c)
For the same reason, adequate
timing between doses and
adequate dosing is essential:
especially in chronic pain which
should be considered a serious
problem and treated so that the
patient is made as comfortable as
possible. Drugs and doses should
therefore be tailored to the needs
of the individual.
d)
More than one kind of treatment
should be utilized. This could be
drug combinations, adjuvant
analgesics, other drugs or
physical methods. Non
pharmaceutical methods of pain
control such as acupuncture.
hypnosis, biofeedback, relaxation
techniques and coping skills
should also be tried. Adjuvant
drug therapy mentioned above
includes psychotropic drugs
which are sometimes useful in
chronic pain since they alleviate
the associated depression and
improve the quality of life.
Benzodiazepines are useful if
anxiety plays a part; chloral
hydrate, if insomnia is present;
antiemetics counter the nausea
and vomiting associated with
short-term treatment with
morphine, and laxatives reverse
the constipation associated with
the long-term use of narcotic
analgesics.
Each case must receive a full trial of
analgesic drugs and other
concommitant physical methods to
relieve the pain. Destructive
methods such as rhizotomy or
cardotomy should be tried as a last
resort especially since these
procedures yield only temporary
relief: in some cases the pain that
recurs is worse than it was prior to
the operation.

Psychological Aspects of Pain
Psychological factors can influence
pain behaviour — to varying extents
— in a considerable number of
patients. The importance of this lies
in its effect on the management of
persons suffering from pain; patients
then need not undergo expensive
and lengthy investigations and, also
the development of many
psychological techniques based on
this, offers help even to those
suffering from pain due to somatic
reasons.
Both physiological and psychological
factors are responsible for the
existence, perception and
persistence of pain. At one pole are
patients with pain that is completely
psychologically determined; at the
the other end are patients where
pain is physically determined;
inbetween lie patients where an
interplay between somatic and
psychogenic factors exists — here
the character and experience of pain
is not fully accounted for by the
lesion.
In the psychological disorders that
are associated with pain, such as
conversion hysteria, depression,
anxiety and schizophrenia, it is only
when the underlying disorder is
corrected that the patient
experiences relief.
Symptoms of an underlying
psychiatric disorder may be
discovered by careful questioning.
The commonest psychiatric disorder
associated with pain is conversion
hysteria; the patient presents with
dramatic complaints, yet may show
indifference to the symptoms, for
example, the patient may smile while
talking about his pain. Patients with
this disorder often have a history of
previous episodes with remissions
and relapses.
Depression is another frequent
cause of pain; the patient gives a
history of feeling depressed before
the onset of pain. Questioning may
reveal that things which had
previously given him pleasure were
no longer so. In addition,
physiological parameters of
depression, such as loss of appetite.
decrease in sleep and loss of sexual
desire may be noted. On the other
hand, patients with organic illness
often become depressed as a result
of the pain, moreso in cases of
chronic pain. The schizophrenic
patient is likely to have bizarre
complaints with disturbances of
thought and behaviour.
attention from others is made
contingent on increasing activity
levels and decreasing complaints of
pain. Analgesics are given by the
clock and not when the patient
complains of pain.
Once a diagnosis is made, the
physician has a large therapeutic
armamentarium to draw upon;
placebo, biofeedback, hypnosis,
behaviour modification,
psychopharmaceutical agents and
psychotherapy,to name a few. A
psychiatric disorder like
schizophrenia responds to
antipsychotic drugs and
psychotherapy, as does depression
to antidepressants. It is important to
remember that a depressed person
is likely to improve with
antidepressants even if the
depression is secondary to pain due
to an organic lesion.
Biofeedback is yet another powerful
modality and has been found useful
for muscle tension headaches
(electromyography feedback) and
migrane (skin temperature
biofeedback) with as many as 70 per
cent of patients remaining free of
migrane one year after treatment. In
addition to these methods are many
other psychological ones;
psychotherapy, where the patient is
challenged to get well and to specify
realistic relationship, work and
recreational goals and the patient is
reinforced for objective evidence of
attempts to achieve the goals set.
Many patients respond to placebo,
but this does not necessarily mean
that the pain is psychogenic. What it
does mean is that the patient is a
placebo responder and that he/she
may yet have an organic lesion.
Probably the most powerful tool in
acute or chronic pain, organic or
psychologically caused, is hypnosis
in this state the person can distort
his/her perception of the pain to
warmth or pressure, thereby
preserving the signal functions of the
pain. Hypnosis can also be used to
induce analgesia or anaesthesia.
The advantage of hypnosis lies in the
absence of demonstrable
physiological risks. An example of its
usefulness was demonstrated by Dr.
James Esdale, a Scotish surgeon in
Calcutta who. in the pre-anaesthetic
days of the 1850s performed 500
major and 1500 minor surgical
operations under hypnosis. He often
undertook operations that in his day
were considered too dangerous to
contemplate.
Behaviour modification has also
been found very useful in pain
management. Pain is often
reinforced by rest, medication and
attention focused on the patient by
medical personnel and family
members. In this approach, patients
are reinforced for behaviour not
compatible with pain: rest and

“It is important not to forget that
non-drug approaches often have a
great deal to offer to the patient
with pain and that a
multidisciplinary approach is often
preferable to a solely
pharmacological one."
"Consider the common experience,
for instance, of being able to
relieve quickly, by means of a hug
and reassurance, the distress and
suffering of a child who had tripped
and fallen. “
“In moments of excitement, stress
or competition, such as on the
athletic field significant injury can
be unattended by pain."
“Reassuring patients prior to
surgery can have a beneficial
effect on the course of
post-operative pain and
requirements of analgesics."

Facts on Fever
Fever is one of the commonest
presenting symptoms a general
practitioner encounters, but it serves
merely as an indicator — a sensitive,
objective and reliable one — of a
disturbance within the body except in
a few instances; It should not be
unnecessarily viewed with alarm and
panic.
These few exceptions are pyrexia of
moderate elevation in patients with
central nervous system disease,
decreased cardiovascular function
(the increased oxygen demand,
cardiac output and pulse rate
associated with fever can be
dangerous on the already
compromised myocardium in these
cases); a history of previous febrile
seizures (particular in children) and
in pregnant women (fever may be
teratogenic for the developing
foetus).' A potentially fatal example
is heat stroke, where temperatures
greater than 106°F (41.1 °C) are
common. Heat stroke is classified as
a hyperthermia syndrome; these are
cases where the hypothalamic
thermostat remains at the
normothermic level, unlike cases of
'fever' where the setting is at a
higher level. In hyperthermia the heat
loss mechanisms fail, causing
temperatures that in some cases
have been recorded as high as
112-113°F (44.4°C)2. Temperatures
higher than this are probably
incompatible with life; in fact,
irreversible brain damage is common
at temperatures of 108°F (42.2°C)
and convulsions are common at
106°F (41.1°C)’ Usually
hyperthermia is seen with cerebral
lesions that involve the
hypothalamus2. Another condition
that causes dangerously high
temperatures is malignant
hyperthermia; this is a group of
inherited disorders which results in
temperatures of 102.2°F to 107.6°F in
response to certain inhalational
anaesthetic agents, such as
haloperidol, cyclopropane, ethyl,
ether or muscle relaxants, especially
succinylcholinefAs with other causes
of hyperthermia, this should be
considered an emergency and
treated immediately. The most
effective measures in hyperthermia
are ice-water baths and, depending
on the cause, other measures, such
as dantrolene sodium, which is

What is generally termed as 'fever' is
an elevation of the normal body
temperature which, depending on the

(36.1-37.2’C). This includes the
diurnal variation of 1°F (0.6’C). It is

Pathogenesis Of Fever
The temperature of the body is
regulated almost entirely by nervous
feedback mechanisms and most of
these operate through temperature
regulating centres in the
hypothalamus. The principal area of
temperature regulation lies in the
preoptic area and, also, to some of
the adjacent parts of the anterior
hypothalamus. These areas contain
heat-sensitive neurons which
increase their firing rate in the
presence of endogenous pyrogen.
Fever is best understood using the
analogy of a thermostat. The
regulatory system at the
hypothalamus balances heat
production and heat loss. Heat
production is principally promoted by
increased shivering and by
peripheral vasoconstriction which
reduces heat loss. Heat loss occurs
by vasodilation (full vasodilation can
increase the rate of heat transfer to
the skin eight-fold and by sweating
(1°C) increase in body temperature
can cause enough sweating to
remove ten times the basal rate of
heat production).4
In fever, the thermostat is at a setting
higher than normal which causes
signals to increase heat production.
The tone in the muscles
consequently increases which
results in shivering, which commonly
occurs during a fever. Conversely,
when fever comes down, the
uncomfortable flushing and sweating

must be palpated with special
attention to supraclavicular and

the abdomen, rectal and vaginal
examination should be done;
valvular anomalies should also be
searched for. Drug intake should be
curtailed for 48 to 72 hours.
Laboratory tests
There are no specific guidelines to
follow: tests should be aimed at the
most likely system that could be
affected, for example, if there is a
suspicion of a connective tissue
disorder, tests as to detect
rheumatoid factor, antinuclear
antibody and antistreptolysin titre
may provide a clue.
Special attention should be paid to
the abdomen, as many of the causes
of unexplained pyrexia lie within.
Treatment
This depends entirely on the
diagnosis which should be possible
in 90% of patients with FUO.5
Fortunately, of the remaining, the
majority recover sponatneously or
respond to medical or surgical
treatment.

The International Study on Agranulocytosis and Aplastic Anaemia (ISAAA)
Agranulocytosis and aplastic anaemia are
exceedingly rare blood dyscrasias which
have been loosely associated with several
drugs. Both disorders can be caused by
many environmental, biological and
chemical factors, including over 100
pharmaceutical drugs. Many of these drugs
have been implicated solely on the basis of
case reports, or without controls, or on
incomplete data reports.
Intentional rechallenge is ethically
unacceptable and specific laboratory tests
do not exist either to label the cause-effect
relation. Therefore, to obtain a reliable
estimate of the incidence of the risk of
agranulocytosis and aplastic anaemia, the
only reasonable approach medically
acceptable was to undertake a rigid
case-control epidemiological study.
This was the genesis of the International
Study for Agranulocytosis and Aplastic
Anaemia.
The study had a supervisory International
Honorary Advisory Board to guarantee full
independence between the organisers and
the sponsors. This Board comprised
eminent experts in medicine and
haematology whose members were Sir
Richard Doll (Oxford), Chairman, P.K.
Lunde (Oslo) and Soen Moeschlin
(Sweden).
Al! co-ordination and data analysis was
done at the Drug Epidemiology Unit at
Boston.
Carefully defined cases, diagnosed and
reconfirmed by an independent
haematological review committee, were
searched for in a time-span of four years.
For each diagnosed case, at least 4
controls were selected who could match
totally with the cases based on age, sex,
occupation, education, social status and
such features.
Specially trained staff questioned all cases
and controls. All haematological data
diagnosis was in line with international
diagnostic criteria.
The study covered 300 hospitals in 6
countries, i.e., Israel, IV. Germany,
Hungary, Italy, Spain and Budapest, with
more than 40 investigators specially trained
to determine drug exposure and other
related risk and disease factors.

Acupuncture in the Treatment of Pain
The late Dr Albert Schweitzer once
said, “Pain is a more terrible Lord of
Mankind than even Death Himself."
The truth of this saying is apparent to
all, yet forgotten when we are not
affected with the symptom. Most
physicians pay inadequate attention
to the treatment of this symptom as it
is a purely subjective phenomenon
which is difficult to assess objectively
in clinical practice. Different patients
have different pain thresholds and
hence respond differently to similar
ailments.
Western medicine is able to deal
adequately with acute severe pain
using narcotics which are however
unsuitable for prolonged use in
chronic pain due to their potential for
habituation and addiction. And the
range of analgesics available —
including the new range of non
steroidal anti-inflammatory drugs —
are occasionally inadequate to treat
chronic pain.
Acupuncture offers an effective
alternative to the problem of pain,
both in its acute and chronic form. At
present enough evidence exists of its
ability to relieve pain and to create
analgesia profound enough to carry
out surgery ranging from
Caesareans to Craniotomies and
open heart surgery. We are as yet
unable to define exactly how
acupuncture produces analgesia,
and several theories have been
propounded to explain the
mechanism of its action. As none of
these is able to completely explain its
action, it is probable that
acupuncture produces analgesia at
multiple levels and the true
mechanism is a synthesis of the
theories described below.
The ‘gate control' theory of Melzack
and Wall propounded in 1965 is the
most popular neurological theory for
the mechanism of action of
acupuncture in the treatment of pain.
According to this theory, perception
of pain is modulated by functional
gates within the central nervous
system. Under normal
circumstances, this gate is wide
open and pain impulses which are
carried by the small diameter fibres
get through quite easily. When
acupuncture needling is carried out,
a second stream of non-painful
impulses is set up via the large
diameter fibres which cause
overcrowding or jamming at the gate,
causing it to close. There is,
therefore, a competitive inhibition of
the pain impulse at the gate. This
gate is postulated to exist at the
thalamic level.
The action of acupuncture should
then be mediated through the large
diameter fibres. However, it was
seen that trans-section of the large
diameter fibres diminished but did
not abolish the analgesic effect. This
led to the finding that the autonomic
nerve fibres accompanying the blood
vessels were also stimulated by
acupuncture. The development of
the humoral theory of the action of
acupuncture was the result of this, as
it was seen that acupuncture
released morphine-like analgesic
substances both in the brain and
peripheral tissues. Over a hundred
neurotransmitters have been
isolated which play a role in
acupuncture analgesia. The two
major groups of these are the
endorphins and encephaiins which
are produced by the Ivsis of betalipotropm.
14
©
Pomeranz suggested that the
endorphins and encephalins
produced by a neuron,binds to an
opiate receptor on the terminal of an
excitatory neuron,partially
depolarizing the terminal membrane,
thus reducing the net depolarization
produced by arrival of a nerve
impulse.
Stimulation of different acupuncture
points augments the secretion of
different analgesic substance and
produces analgesia in different
areas. Stimulation of the
acupuncture point HEGU situated on
the dorsum of the hand between the
1 st and 2nd metacarpal bones leads
to production of alpha-and beta
endorphins in the ratio of 2:1.
Alpha-endorphins induce analgesia
in the region of the head and cause
a slight tranquilhsation. Hence.this
point is used to treat toothaches,
headaches, and;trigeminal neuralgia,
as well as to create analgesia for
tooth extraction and tonsillectomy.
Beta-endorphin creates analgesia all
over the body and is released by
stimulation of most acupuncture
points. These substances also cause
slight sedation which potentiates the
analgesic effect.
Acupuncture, contrary to popular
belief, is not very painful.
Acupuncture needles are normally
30 to 36 gauge (0.32 mm to 0.18 mm
in diameter), which is little thicker
than a human hair. The photograph
shows a little girl undergoing
acupuncture therapy.
In osteoarthritis, damage to the
articular surface causes pain. This
leads to a protective spasm of the
surrounding muscles to restrict
movement and pain.
This spasm also pulls the joint
surfaces closerand increases
damage to the articular surface. This
again creates pain, setting up a
vicious cycle (see Fig below).
This cycle is difficult to break with
conventional medical treatment.
Acupuncture relieves the pain in
sittings,thus breaking the cycle
and affording the patient a pain-free
existence for 2 to 5 years before the
pain recurs.
In sciatica, we needle points which
lie along the course of the sciatic
nerve. This serves to relieve the pain
and relax the muscular spasm of the
paraspinal muscles, making
movement easier. This is effective in
giving relief from pain within 8 to 10
sittings in most patients.
Acupuncture is also effective in
relieving pain by needling areas
which are distant from the affected
area. In frozen shoulder, a needle
placed a few inches below the knee
next to the tibia and rotated
vigorously for a minute permits
immediate pain-free mobilisation of
the shoulder. This is one of the most
dramatic demonstrations of the
efficacy of acupuncture.
Acupuncture points are situated on a
series of pathways called meridians
which criss-cross the body. These
pathways are traditionally said to
allow the flow of certain life forces.
Needling is said to restore the
balance of these forces,the
disruption of which was thought to
cause disease.
Similarly, there exist acupuncture
points in the ear (over a hundred of
them) by the use of which it is
possible to treat most ailments. The

Weighing Risks
Taking risks or avoiding them is
intrinsic to life. As we grow older we
veer away from the former towards
the latter with the quest for vanished
youth during the middle years
expressed by a shiftback, for a short
time, towards risk-taking again.
To grasp opportunity, one must act,
and inherent in this,is the element of
risk; opportunity and risk cannot be
separated. When fear paralyses
action, opportunity fades.
Understanding risk means learning
to balance fear and opportunity. In
this attempt strange paradoxes
occur which highlight the magnitude
in which risk is misunderstood, and
this is the basis for some of the
strikingly distorted perceptions of
risk!
Cigarette-smoking is deemed
responsible for half-a-million
premature deaths per year from lung
cancer and heart disease in the U.S.
alone — but this fact only gets a
small amount of coverage in the
news media even though the number
of smoking-related deaths is
equivalent to three fully loaded 747
jets crashing every day. Yet, when
an actual jet crash occurs, it is given
“Big Attention".
That 'bad news' sells is nothing new.
What is new is the instantaneous
dissemination of news — one of the
gifts of modern electronic
technology.
Many widely accepted human
activities are the very essence of
risking life or limb. (Table)
Quantifying or measuring risk
permits a rational approach which
can allow people to make their
choices based on information rather
than on imagination. Imormation is
crucial to this concept, but the
methods of generating the
information that one needs to assess
risk are often uncertain and.
moreover, the methods of
communicating this information, viz.,
expressing risk are usually
confusing, misleading and
emotionally charged.
To understanding risk, one has to
take a big step beyond the

journalistic view. It is necessary to
perceive the number of victims in
relation to the number of people who
did just what those victims were
doing,but yet managed to emerge
unharmed. This would be the
genesis of avoiding what is known as
Victim-Oriented Reporting.
Thursday, the average number of
traffic deaths is 75 per day. From
Friday through Sunday the average
number is 240 per day. In other
words, a 3-day holiday weekend
might be expected to produce 3 x 240
= 720 victims.
To illustrate the kind of
misinformation which victim-oriented
reporting can generate, have a look
at the following headline in the USA;
“411 DIE ON HIGHWAYS DURING
LABOUR DAY WEEKEND".
The alternate headline to the one
above should have been "CAREFUL
DRIVING ON LABOUR DAY
WEEKEND — 309 LIVES SAVED."
But human nature yearns for tragedy
or bad news. Good news in our
emotional makeup must take a
second place.
First spontaneous reaction — How
awful!!
An analytical look behind the
headline:
50,000 traffic accidents occur in the
U.S.A, every year, i.e., 137 per cent
per day of 411 in 3 days. Since
Labour Day weekend is 3 days, the
411 turns out to be the right average.
A closer analysis of that headline:
An average of 137 per day is
misleading as there is a strong
difference between weekday and
weekend incidents. Monday through
Victim-oriented reporting is designed
to leave us with anxiety and fear of
such things in no particular order —
the bomb, the next earthquake, a jet
crash, a chemical plant fallout.
passive smoking, AIDS. The list can
continue endlessly, as long as it sells
unpleasant events.
To give some order to these high
nsks we must have a “Scale for risk'
which integrates information so that
rational people can make rational
decisions about which hazards
present high risks and which are
accompanied by small risks.
The lack of acceptance of a uniform
standard for expressing risk is one of
the reasons that we haggle a great
deal about certain risk-related
issues.
Just as the Richter Scale in an
earthquake report tells us about the
severity of the quake, we need to
have an analogous risk scale so that
everybody can understand to what
extent, for example, a newly
discovered hazard affects our
already known health risks.
In making such a scale, it is
important to keep it very simple.
Instead of saying “the death rate
from homicide in the USA is 10.4 per
100,000 per year”, a simple way of
representing this figure is by saying
“the risk of one’s dying due to
homicide in a year's time in USA is 1
in 9615".
The number ‘1' means that the event
in question happens to you or to
someone else. The chances of ‘1'
becoming a victim to a hazard is his
or her risk.
The Risk Ratio is a ratio in which the
numerator represents the individual
who is actually harmed while the
denominator represents the number
of all persons who are exposed to
the same activity but have emerged
unhurt. For example, all airline
passengers, all persons with high
B.P., all cigarette smokers, etc. The
risk ratio varies from 1 : 1 to 1 : 100
million representing a scale of 0 to 8
(Fig.1), where each number
represents the number of zeros after
1.
A 1 :1 risk occurs when a person
contracts a disease such as rabies
which has the virtual certainty of
death.
There is no theoretical upper
boundary to the scale, but 8
represents this limit which has been
set by the present methods of data
collection. And so, now we see the
basis for making easily understood
statements such as "my risk erf being
killed as a passenger in an air crash
is 1 in 800,000 per trip or, if using the
above scale,the risk is between 5
and 6. Fig.2 compares the risk of
various activities.
For greater accuracy any risk
statement necessitates a time
interval to be expressed. In general,
either of two time intervals are used
per year or per event, i.e.. per trip or
a surgical operation or giving birth or
any such parameter.

methodology is the basis of the

One could use the Risk Scale to
place some of the known side-effects
of drugs in relation to other risks of
life (Fig.3). As an example, the
occurrence of agranulocytosis
consequent to drugs occurs on this
scale with a frequency so low that
the chances of being struck by
lightening or even encountering a car
accident are very much higher.

Medicine and surgery are both
naturally linked with risks.
Contemporary medicine could never
have brought solace to patients
without the accompanying risks of
therapy. Where would open-heart
surgery, valve replacement and the
like be today if the initial patients had
not taken the risk of undergoing the
surgeon's knife?
10 1-

—————-Like all activities, drug treatment is
also a calculated risk. HOW SAFE IS
A DRUG? — this question is often
asked. The safety of a drug is always
assessed first by studies on animals
and later in extensive clinical trials in
human volunteers under regulated,
approved ethically designed and
closely monitored clinical trials.
The sample size required for
detecting the occurrence of adverse
drug reactions (ADR) varies and
depends on the frequency of the
reaction. If the frequency of the ADR
is 1 : 10, then the number of patients
needed to have noted this would be
39 - 40. Similarly,for a 1 : 100 ADR,
390 - 400 patients would have been
required; for 1 : 1000, 3900 - 4000
patients and for a 1 : 100,000, a
corresponding 390,000 - 400,000
patients. It is therefore almost
impossible to detect rare ADR.
18
Therefore the next time such a
''sensational" news report appears,it
would be very necessary to recall
that the information is next to nothing
if not presented along with the
comparative data or the hidden facts.
However, two kinds of studies to
detect rare ADR have been
epidemiologically identified:
a) The cohort type: Individuals likely
to develop the disease are
studied even before they suffer
the pathology. They are followed
up for prolonged time periods to
determine when the exact
occurrence takes place. This
method obviously has
tremendous constraints in terms
of finance and time.
b) The case-controlled type: Every
case identified is compared with a
large number of controls who are
necessarily matched for all
identifiable variables with the
suffering case. In so doing it
allows the exploration of all
possible causal factors related to
the event, and also provides a
The risk of treating versus not
treating is often the genesis to know
how small risks can become the
basis of big controversies.
The problem with drugs is not that
their risks are greater than their
benefits. It is simply that we cannot
make up our minds about the risks
— which risks are tolerable and
which are not acceptable.
The tendency of people to worry
about rare side-effects and forget
about the benefit of the drug is due
to our failure to calculate risks, to
assess them and to compare them!
Prof. William Inman of the Drug
Surveillance Unit of the University of
Southampton has very aptly spelt out
the benefits of a drug versus the risk
of a drug-free existence, when he
says "One way to consider drug risks
is to ban all drugs. Ending all druginduced harm would add 37 minutes
to your life expectancy. Ending all
drug-related benefits would subtract
15 years from your life expectancy,
and also end the improvement in life
quality drugs give".

Hoechst AG, at West Germany,
being a manufacturer of the drug
and concerned about the safety of
its products immediately took steps
to determine the true incidence of
this disorder and assess the safety
of analgin.
In 1979, a massive study was
initiated in collaboration with the
University School of Medicine at
Boston, USA, to determine the true
incidence rates associated with
analgesics, not only for
agranulocytosis, but also for the
dreaded disease, aplastic anaemia,
which has a fatality rate of about
50%. 300 hospitals from 6 countries
(West Germany, Israel, Bulgaria,
Hungary, Spain and Italy) covering
a total population of 22 million
people became the study base. A
team of experts examined all
laboratory material, i.e., slides of
blood and bone marrow to reach a
diagnosis independent of
This error in previous calculations is
totally mind-boggling — consider
therefore with such an enormous
figure, the incidence of
analgin-related agranulocytosis in
Bombay city alone should be of the
order of 56,000 cases.
Dr. Samuel Shapiro, member of the
ISAAA Study Group, accurately
summed up this high-blown error
when he stated at Stockholm last
year that “the original estimates of
agranulocytosis was an error of
many orders of magnitude.”
In fact, the study data presented
showed that the risk of getting
agranulocytosis following analgin
was as low as zero to a maximum
of one in one million users.
Along with analgin, the study also
showed that a few other drugs like
sulphas and commonly used
analgesics have the potential to
cause agranulocytosis, the
commonest being indomethacin.
which is surprising because this
substance was never suspected to
be a high-risk factor to get
agranulocytosis. Moreover,
indomethacin also was associated
with aplastic anaemia. This disorder
is unrelated to the use of analgin.
At this conference, it also became
evident that other major pain-killers,
like aspirin bear the risk of rare but
severe adverse drug reactions. The
risk of gastrointestinal bleeding is
substantially increased often to a
fatal end. Aspirin was also
associated to an appreciable
extent with aplastic anaemia. With
paracetamol, the other common
pain-killer, no association with
either disease could be found, but
the experts stated, there were not
enough cases of individuals
exposed to the drug.
Analgin is almost 65 years old. Yet
it continues to successfully vie with
its younger competitors for the
pride of place among not only
pain-relieving drugs, but also
among fever-reducing agents
because it has the twin combination
of proven safety and efficacy.
According to Dr. T. Floeter, Doctor
of Anaesthesiology who runs a Pain
Clinic in Frankfurt, “Analgin is
irreplaceable among peripheral
analgesics. Its therapeutic uses are
so broad and yet no case of
poisoning has been observed".
Current research indicates that the
drug is superior to aspirin and
paracetamol for the relief of pain
and fever.
All analgesics, like any drug, have
some element of risk involved with
their use because they, like any
other drug again, can cause a
hypersensitivity reaction in an
isolated patient, but this is an
extremely rare phenomenon and
the side-effects which are usually
talked about so loudly are so
extremely rare that most doctors
have an occasion to learn about
them only from textbooks.
Any drug at any time is always a
risk to the user, and drug-related
risk is always a concern. A risk-free
drug has yet to be found and
therefore every drug needs to be
evaluated not on the isolated case
of adverse effects, but on the vast

Emergencies in Clinical Practice
Acute Myocardial Infarction (AMI)
Approximately 40-50% of persons
who suffer an acute myocardial
infarction die within 20 days of the
onset. If one takes into consideration
that half these deaths occur within
the first and second hour after the
onset of the symptoms, the urgency
to provide prompt treatment is further
stressed by the fact that the majority
of these deaths are due to potentially
correctable ventricular fibrillation.

On auscultation, a fourth or atrial
sound is present and may be
palpated as a presystolic expansion
over the anterior aspect of the left
ventricle. With extensive myocardial
damage, a third heart sound is
present often accompanied by a
systolic thrust palpable over the 3rd
and 4th intercostals.

Convulsions in Children
To be called to a child having a
convulsion is a disconcerting
experience. Often by the time you
reach him the fit is over. If it is not,
all you need do is to prevent him
hurting himself. When the jaws are
already in spasm you may cause
damage by forcing them open but a
gag may be used if the airway is
obstructed. The parents will be
alarmed and it is important to
behave in a reassuring way. Let
them see that you know what you
are about. Prevent them from doing
silly things. It is comforting to them
to see a cold compress being
prepared and even to help you or
Sister to put it on the head. In the
rare case where fits continue
without a return of consciousness
(status epilepticus) they must be
stopped, for prolonged convulsions
are incriminated as a cause of
temporal lobe epilepsy. Give
diazepam 5 to 10 mg by slow i.v.
injection or rectaliy. An alternative
is paraldehyde 0.1 mg/kg i.m. which
can be repeated after an hour,or,phenobarb 6 mg/kg i.m. Remember
that a plastic syringe cannot be
used for paraldehyde. After the fit is
over try to find the cause. This
varies with the age of the child. In
the newborn birth injury is likely.
Hypoglycaemia should be looked
for because it is easily missed and
otherwise disastrous. In the toddler
febrile convulsions are common
and in the older child epilepsy,
intracranial disease (meningitis) and
nephritis should be thought of.
About 1 child in 15 has a
convulsion and at least one-third of
these are simple febrile
convulsions. So be reassuring to
the parents. The outlook is good if
the child is mentally and structurally
normal and if the fits are brief,
albeit recurrent, complications of a
febrile illness (‘benign febrile
convulsions') as distinct from true
epilepsy precipitated by fever.

THE PAIN SYNDROME
/T)
A pain sensation pulls a person
immediately into an isolated orbit in
which he remains alone with a
personalized experience, since pain
is a very private sensation. An
individual may try to express pain
verbally or through behavioural
changes which may not however
convey the actual sensation or
intensity of pain. This makes pain an
essentially abstract concept, though
it is a very tangible hurt — a hurt that
can be only insufficiently
communicated. Besides, pain perse
is seldom uniform in its effect on
people, because of the structural
differences among them, the
differences in their levels of
tolerance as also in their attitudes
which condition their total perception
of pain.
The Role of Pain Expressions in
Medical Diagnosis
Expressions of pain are of immense
value in medical diagnosis. The
physician is heavily dependent on
the patient's report of pain, itsnature, location, intensity, duration
and so on. By the virtue of the power
of articulation and expression,
human beings are better subjects
than animals for the study of pain.
The study of pain is difficult as not all
aspects of pain are available for
scientific enquiry. However,
externalised ‘behaviour’ due to pain
is observable and therefore can be
described in visible terms which
makes it less of an abstract concept.
Signs of writhing, gritting of teeth or
withdrawing from pain, for instance,
may find supportive verbal
expressions to describe the agony
one feels. Pain can be described in
neurological or in psycological terms.
By recording the verbal signals of
pain, medical science is greatly
assisted in discriminating varieties of
pain, both in their nature (muscular
ache, scalding, burning, stabbing,
smarting, throbbing) and degree
(severe, mild, bearable, etc).
Although these may be clothed in
culturally defined styles,one can
nevertheless zero in on certain
features to deduce the nature/source
of the pain.
Pain as a Defence System
Pain promptly set up an alarm to the
brain, putting it on the alert about
harmful, external influence on the
body. This new perception of pain as
a warning and a protective reflex
alters its role from a negative
concept to one of extreme
importance, since it attempts to
protect the body. This can even be
seen in the effective way in which a
reflex withdrawal prompted by a burn
or an electric shock, minimises
injury.
Pain Receptors
Pain signals are picked up by nerve
endings which are called pain
receptors. They mediate a response
signalling pain impulses to the brain
and setting off the first alarm that
something is wrong with some part of
the body. The central nervous
system helps locate the source of the
pain. Pain receptors are of various
types, each of which responds to a
different sort of tissue damage, such
as from a cut or that caused by heat
or chemicals. It is important to
remember the same kind of pain may
evoke varied intensities of responses
from different individuals, depending
upon the individual degree of pain
tolerance and the pain threshold.
Kinds of Pain
Pain sensations are of various types.
For instance, a sprain in the leg feels
different from the sharp pain due to
an abrasion; a pervasive toothache
feels different from a burnt finger or a
headache. Pain varies in duration
too. It can be intermittent, prolonged
or even chronic: in some cases, it
may persist for months or years,
disrupting the lives of the suffering
individuals. There is also the
“referred pain”, a situation in which
an area of the body may indeed hurt,
but the real origin of the pain may
reside elsewhere, in a region far
removed from the area. This
21
"referred pain" can lead to an error in
localization.
groups like the Jews and Italians
implicity encourage complaints of
pain, while others discourage it.
Kinds of Pain Responses
There are as many kinds of pain
responses as there are kinds of pain.
To cite some, neurological,
physiological, verbal, behavioural
and "affective" responses to pain
exist. From the medical point of view,
physiological responses are more
reliable than verbal expressions;
changes in blood pressure, heart
rate, dramatic changes in muscle
tension or sweating, help in arriving
upon objective data. And yet,
medical diagnosis does not
underestimate the “affective"
descriptions of pain as they come
closest to the essentially personal
experience of pain and its
uniqueness. All the classifications
talked about earlier— physiological,
neurological, behavioural, "affective"
— are confusedly abritrary, whereas
in reality they are mutually inter
related and integrated by the
individual who experiences pain.
Classifications that go against this
holistic view of pain are only resorted
to as clearing-aids for medical
diagnosis and treatment.
A Puzzling Phenomenon
When pain enters a less tangible
plane, it becomes more challenging
for the medical profession to
alleviate suffering. There are three
puzzling phenomena of pain which
are identified — insensitivity to pain,
phantom pain and the hypnotic relief
of pain. The first is by no means a
blissful condition,for often persons
who fall in this category have other
associated neurological defects. The
second, 'phantom pain; may occur in
a non-existent location as in the
imaginary pain in a leg which has
been amputated long ago. Hypnotic
analgesia is another area which
causes a patient to accept even the
worst, whatever iliogic it involves.
Conditioning
The familial, social and cultural
environment along wi’Ji
temperament and personality
‘condition’ a person. A neurologist,
physiologist or psychologist is each
dependent for his data on the
patient’s cultural conditioning,
upbringing, and discipline. For
example, the Irish are supposed to
be inhibited in their expressions of
pain,while the Americans tend to
"take pain in their stride” (which is
believed to result in less anxiety and
higher tolerance). Certain ethnic
22
Apart from cultural conditioning,
personality traits, such as an
extraverted nature, results in
relatively low anxiety states,
whereas a neurotic temperament
produces greater anxiety. Pain
tolerance also varies with the
presence or absence of sympathy
from the family or attendants.
Pain Threshold
Pain threshold (which is not quite the
same thing as pain tolerance) is
roughly the same in all people even
from diverse ethnic groups. In
patients with “low painful threshold’,’
pain occurs with negligibly painful
stimuli, while those with “high painful
threshold" may bear severely painful
stimuli uncomplainingly. Extreme
stress and shock are also known to
numb pain, for the brain
manufactures its own opiates,
resulting in what is medically termed
as "stress-induced analgesia.”
Coping with Pain
Coping with pain involves a thorough
understanding of the pain situation
which, in turn, requires education not
only in the endurance of pain, but in
understanding the limitations of
preferred relief as well. Two old
methods for minimising pain are
application of heat or. cold compress
to give a temporary respite from
pain. Massages and exercises have
also been tried. In electrical therapy,
electrical impulses of adjustable
intensity and frequency are applied
through small skin electrodes to
stimulate (cutaneous) nerve endings
and muscle fibres. This treatment,
however, is known to give relief only
as long as the stimulation is
continued. Surgical measures of
pain relief are undertaken in extreme
cases. Acupuncture is an ancient
treatment where needles inserted
into ‘acupuncture points' relieve
pain. Psychotherapy sets about to
change thoughts and ideas of the
patient simultaneously, and obliquely
appealing to the patient’s will in
coping with pain.
Pain Relief
Treatment in medicine has one
major aim — to relieve suffering.
Anaesthetics make surgery possible
without pain by preventing pain
signals from reaching the brain.
Local anaesthetics block the sensory
nerves which conduct pain. In
addition to anaesthesia are a variety
of substances that help in the safe
elimination of pain. Analgesics like
asprin, analgin and paracetamol are
given in effective doses and are
sometimes also given in anticipation
of pain, it is when it comes to chronic
diseases that the benefit-risk ratio of
drugs must be carefully weighed.
Modern therapy has now stretched
to para-medical areas. Ordinary,
everyday work is in fact looked upon
as an occupational therapy. Modern
medicine, therefore, drastically
curtails the duration of
convalescence. It encourages the
patient to get on to his feet as fast as
he can and on to his work
environment for that will surely help
in dispelling his pain symptoms.
Doctor-Patient Relationship
This relationship is so important that
it could be the cornerstone of
therapy. The doctor should
acknowledge the reality of the
patient’s experience, encourage the
patient to express himself and show
a willingness to understand what he
says. Medical ethics has developed
enough to understand the obligatory
need to give a patient all the
information he needs regarding his
condition.
Knowledge of his condition may help
the patient regain his confidence and
reduce his anxiety. For a good
doctor-patient relationship, it is
equally important for the patient not
to be passive but responsive and co
operative with the doctor who is,
after all, trying hard to contend with
the pain as much as the patient
does.
Pain is a reality. There is now a more
comprehensive, holistic view of pain
than before, which takes into
account the patient's mental agony
together with his physical suffering.
Medicine no longer dismisses
intractable pain as “psychological"
nor does it like the idea of making a
patient toss between "psycho" and
somatic’ evaluation. It realises that
it is our thinking here which is
dichotomised and not the pain
sensation in itself, which is inherently
physical, mental, psychic and
somatic, all in one.

The Issues
i.
According to Hoechst,
approximately 25 tonnes or
18.5 million doses of Novalgin are used world wide
everyday.
With most of the developed nations banning
or restricting its use,
it is obvious that it is sold
mainly in third world countries.
The countries which have banned Dipyrone have been
managing pain without Dipyrone by using equally
effective and sage analgesics.
ii.
The
'Boston Study' generated a lot of controversy,
since Hoechst used the results even before publication
for a misleading advertisment campaign showing the
occurence to be 1 per million.
The Hearing of the
German Federal Health Office finally confirmed the
assumption of 1 per 30,000 to 60,000 to be nearer the
mark, or one tablet per 70,000 consumed could cause
agranulocytosis based on this same study.
The limitations of this study are,
a.
that
it excludes all patients
i.
who die of agranulocytosis without receiving
ii.
who die without having a white cell count,
iii
who have undiagnosed agranulocytosis and
medical aid;
and
recover from it.
b.
The study does not look into other side effects
of Dipyrone,
like shock,
fall in B.P.,
Urticaria etc.

c.
The data presented in the intermediate and
final reports are inconsistent.
d.
Whereas 400 cases of agranulocytosis were
registered to assess risk properly, only
221 cases were analysed in the final report,
e.
and
There is extreme variability in data between
different countries and even within the same
country.
f.
Some data were seen to be clearly unreliable.
iii» The findings of the controversial

ature in different countries is being practiced.Even
claims of anti-spasmedic action which is not
scientifically substantiated is being made.
Any

non-existant beyond the literature supplied by the drug
companies.
iv.
Since 1985, Dipyrone (Analgin) has not found mention
in any standard medical text books,
except for naming
it as a drug which can cause agranulocytosis.
v. Even in our country,

In India
In 1983,
the G.O.I
banned the manufacture and sale of
Amidopyrine but not dipyrone.
The Drugs Consultative
Committee had recommended ban on FDCs of dipyrone also,
but this seems to have slipped from the banned list.

The Government is the largest
manufacturer of Dipyrone in
this country.

Analgin is among the largest selling analgesics in the
country with sales figures accounting for Rs. 70 million.
There are approaimately 200 formulations containing
Analgin,
including injectables,
and drops for newborns
and infants for colic.
4.
Analgin is available as O.T.C inspite of its being a
Schedule H drug in our country and the attitude of the
prescribing doctors as per a study (Lancet 86) was "if
I
prescribe it 30 times a day and it is available over the
counter it must be safe".
In a field study (Lancet 86)
it was seen that the pyrazolones made up the majority of
both G.P prescriptions and O.T.C sales of Analgesics.
One more of these drugs were given to over 50% of patients
requesting an analgesic.
5.
Drug action groups have initiated a campaign on Analgin
especially at ACASH,
Bombay,
D AF West Bengal ano AIDAN,
New Delhi.

Analgin induced agranulocytosis does occur in India,
especially if one looks for it systematically as
Bombay haematologist B.C.Mehta has done.

12-15 cases of agranulocytosis a year, of which 10-12
are caused by Dipyrone or Dipyrone containing drugs.

Even
in India,

it could be 15

Wider issues
Developing countries like ours are ill placed to afford
expensive and useless health care products and definitely
not the frankly dangerous ones.
We have unsophisticated consumers and poorly developed
regulatory and advisory systems - this is fertile ground
7

for pharmaceutical companies to indulge in unacceptable
practices.
The vast majority of rural doctors working in nrofessional
isolation have no access to independent information on drugs
they prescribe.
Here,
the representative of the pharmaceutisel
company who is ill-informed himself and paid by commission
on drug sales becomes an ideal tool to promote the interests
of the Pharmaceutical company*
Thus,
it appears that the consumer is at the mercy of drug
manufacturers.
Other than an appeal to the Food and Drugs
Administration,
the Central government and the HRTP Commission
the consumer is virtually without recourse to any independent
body such as the judiciary.
The 3.3 Hospital Commission (Lentin
Commission)
enquiry reveals the ineffectiveness of these
agencies.
The consumer protection Act of 1996 is expected
to offer some hope.
In effect,
only a public outcry by the consumer can force
Voluntary withdrawal by or reform by drug companies.

-vjuct—sphingolipidoscs (eg, Tay-Sachs disease),
%copolysaccharidosis
(eg,
Hurler
disease),
..^proteinoses (eg, fucosidosis), mucolipidoses (eg,
disease), and type II glycogenosis (Pompe
jjj^ase). Acid hydrolase deficiencies are due to a series
^single-gene mutations with the following results:
failure to produce immunologically detectable
• aizy1710 glycoprotein (CRM ); production of
cjtaJytically inactive or inefficient protein (CRM-);
reduced or absent post-translation processing of
rjre enzyme protein; excessive post-translation
processing; failure to glycosylate the enzyme protein;
failure to generate the mannose-6-phosphate
recognition marker which enables the enzyme
molecule to follow its correct path to the lysosome
after it has been glycosylated in the Golgi apparatus;
lack of an enzyme activator or protector protein; lack
of a substrate activator protein.
Each of the main types of gene-product
abnormality can be due to several different
abnormalities at the genomic level. Thus CRM
negativity may be due to a lesion of the gene directing
the synthesis of the enzyme protein (and this can itself
be due to premature insertion of a termination codon,
deletion of a major portion of the gene including the
coding region for the immunogenic site, mutation or
deletion of a start codon, or a splice-mutation);
transcription failure; translation failure. The CRMvariants of these diseases show a similar range of
genomic lesions which modify the activity of the
catalytic site on the enzyme molecule without altering
the immunogenic site. In addition to, or instead of,
modifying or abolishing the catalytic site, the genomic
lesion may lead to an abnormal gene product (the
enzyme) with reduced affinity between subunits,
reduced stability, increased susceptibility to
proteolysis, or reduced solubility with impaired
mobility in the reticular system and Golgi apparatus.
Lack of an enzyme activator or protector protein, or of
a substrate activator protein, can be the result of a
^similar range of genomic lesions. Lysosomal storage
diseases that are due to lysosomal acid hydrolase
deficiencies have now been reviewed in a monograph1314
15
and the biosynthesis and intracellular migration
(“trafficking”) of these enzymes have been intensively
studied by several groups of workers.1415
In Salla disease16 there is abnormal lysosomal
storage and urinary excretion of N-acetylneuraminic
(sialic) acid,17 and -the disorder was provisionally
grouped with the glycoproteinoses.18 It is now clear
that the disease is attributable to a transport defect
whereby sialic acid cannot be transported out of the
lysosome.1’-20 Salla disease is an autosomal recessive

disorder which appears to be confined to individuals
of Finnish descent, and which derives its name from
the region of Finland whence most of the patients have
originated. Patients show muscle hypotonia and
psychomotor delay by 4—12 months of age; motor
incoordination, dysarthria, dyspraxia, and mental
handicap then become apparent. Some patients have
epileptic fits and muscle rigidity, torsion dystonia, and
signs of an upper motor neuron lesion may be
apparent later. Salla disease is the first disorder shown
to be due to defective transport of a monosaccharide
across the lysosomal membrane. The findings arc
consistent with sialic acid egress from the lysosome
being mediated by either a diffusional or facilitated
transport system, but it has not yet been possible to
demonstate the saturability of the system which is
required to establish the existence of a specific carrier
mechanism or carrier protein. Nevertheless, there is
some circumstantial evidence for the view expressed’
by Renlund et al that “a single gene product, a specific
carrier, mediates the transfer of NANA (sialic acid)
across the lysosomal membrane”.20
Cystinosis is no longer the exception among the
lysosomal storage diseases but the archetype of a new
subset of these disorders, and a disease due to defective
transport of vitamin B12 across the lysosomal
membrane is already known.21 One family has been
identified in which a lysosomal hydrolase deficiency
(Fabry disease) and a lysosomal transport defect
(cystinosis) occurred in different members of the same
sibship.22 The lysosomal transport defects may well
prove to be as important and varied as the diseases
caused by deficiencies of lysosomal hydrolases.
ANALGESICS, AGRANULOCYTOSIS. AND
APLASTIC ANAEMIA: A MAJOR
CASE-CONTROL STUDY
AGRANULOCYTOSIS and aplastic anaemia are rare but
commonly fatal complications of drug treatment. Their
rarity has made it difficult to assess the risk associated with
individual drugs; estimates have often been alarmingly high
or complacently low. Now the first findings from a large
case-control study offer some answers about analgesics.1
The impetus for the work was a stark difference of opinion
about the safety of the pyrazolone analgesic dipyrone. As we
noted last month,2 Hoechst, the major manufacturer of the
drug, needed clear evidence that it was acceptably safe, and
so sponsored the independent International Agranulo
cytosis and Aplastic Anaemia Study. Funds were also
contributed from Hungary, Bulgaria, and Sweden. The

study was coordinated and the data analysed by the Drug
Epidemiology Unit in Boston and supervised by a
distinguished honorary advisory board.
The study aimed to collect all cases of agranulocytosis and
aplastic anaemia that were admitted to hospital (community
cases) or that occurred during a stay in hospital (hospital
cases) in each of seven regions—Israel, Barcelona, Ulm,
West Berlin, Milan, Budapest, Sofia, and Stockholm/
Uppsala—with a total population of 22 3 million people.
The attempt to include the region of Sao Paulo failed. Great
care was taken to prove the diagnosis. Detailed drug
histories were obtained from the patients, focusing
especially on the seven days before admission
(agranulocytosis) or on the preceding six months (aplastic
anaemia). The interview included presentation of a long list
of generic and brand names. Controls for ±e community
cases were selected from patients admitted to the same
hospitals, but the prospective controls for the hospital cases
were too ill to be interviewed. Conclusions about individual
drugs had to be based on the community cases alone.
The annual incidence of verified cases of agranulocytosis
ranged from 1-7 to 9 0 per million in the different regions.
This of course excludes mild cases that were not recognised
and those that died before the diagnosis could be made.
Some cases might also have attended hospitals outside the
catchment area. The fatality rate was 10% among
community cases and 6% among hospital cases. Regional
fatality rates are not reported, perhaps because they might
be taken to reflect differences in the effectiveness of medical
care. The real meat of the report lies in the estimates of risk
associated with different drugs. A rate ratio (rr) for each drug
was obtained from the number of community cases and of
controls who had taken it in the seven days before admission
to hospital. One-third of the 300 community cases were
excluded because they were not interviewed (21 had died),
or because the day of onset could not be determined. For
dipyrone, but not for any other drug or group of drugs, the rr
varied greatly between regions, ranging from 1 and 2
(Budapest, Israel) to 21 and 31 (Berlin, Barcelona). These
huge disparities raise some doubts about the results, for they
were not due to differing incidences of agranulocytosis, but
to very high and perhaps untrustworthy figures for dipyrone1
use by the controls in Israel and Budapest. Despite the low
rrs for these two regions, 18% of their cases were apparently
due to dipyrone, hardly less than the 23% in the study as a
whole. Some of the doubts might have been resolved by
examining sales data, but none were used—although
Laporte, one of the investigators in the study, has presented
such figures.3 The estimate of the excess risk from dipyrone
is expressed rather oddly, as 1 1 per million takers during a
seven-day interval. The calculation underlying this estimate
is not explained. The peculiar denominator is difficult to
apply to real life. The risk for exposure during one year
could be up to 50 times higher. It would be expressed more
clearly as the number of cases per million defined daily doses
(DDD), or per 100 000 packs sold.
Other analgesics
significantly associated
with
agranulocytosis across regions were indomethacin (rr
estimate 9) and the butazones (rr 4). Numbers were too
small to allow estimation of rrs for other pyrazolones such as
amidopyrine which is an acknowledged cause of agranulo
cytosis, or for other anti-inflammatory analgesics (NS AI Ds)

which are not. Use of salicylates or paracetamol was not
associated with agranulocytosis or aplastic anaemia. These
findings reinforce the arguments for banishing dipyrone2
and where possible using paracetamol or aspirin instead.
The data on aplasdc anaemia also bring some surprises.
The overall annual incidence was 2-2 million, with a
two-year fatality rate of 49%. Analgesic use by cases and
controls in the period between six months and one month
before hospital admission yielded rrs for individual drugs or
groups of drugs. Histories of any exposure to indomethacin
(rr 13), diclofenac (rr 9), and butazones (rr 9) were
significandy associated with—aplastic anaemia. For
prolonged exposure to indomethacin or butazones the rate
ratios were around four times higher; but these were based
on small numbers. For the same reason, no rrs could be
calculated for pyrazolones other than dipyrone, or for
individual NSAIDs. The data thus do not incriminate other
NSAIDs, but they raise ±e worrying suspicion that
indomethacin, the butazones, and diclofenac may not be the
only ones to carry a risk ofaplastic anaemia. It certainly looks
as if indomethacin ought to join phenylbutazone as a drug of
last resort, but while data on the other NSAIDs are lacking it
seems premature to regard diclofenac as a second-line drug.
This study is the first of its kind, and the courage and
tenacity of the investigators in carrying it through despite
some serious setbacks must be applauded. It confirms that
dipyrone is a major cause of agranulocytosis and/that
phenylbutazone, indomethacin, and diclofenac can cause.,-.
aplastic anaemia. It is now up to all of us—prescribers, drug
regulators, and pharmaceutical companies—to use the
results in the best interests of patients.
RESEARCH ON HEALTHY VOLUNTEERS
CONCERN about drug safety has led progressively to more
stringent licensing requirements and more comprehensive
investigation of drugs before they are marketed. As a result,
more early phase trials are being conducted on healthy
volunteers; the wheel has now turned full circle with two
well-publicised reports of fatalities. The Medicines Com
mission responded by asking the Royal College of Physi
cians to set up a working party on research in healthy
volunteers. In its report* the working party attempts to
establish safeguards for such volunteers and recommends
procedures for compensation in the event of harm.
Volunteer experiments are in danger of becoming big
business. Several contract companies have been established
to sell volunteer studies to phannaceutical firms which lack
the necessary in-house capacity. Such developments pose
two important questions about those who carry out the work
and those who volunteer to participate. Firstly, the facilities
for early-phase studies have in some instances fallen weU
short of the ideal; in other cases, university or hospital staff
have used the resources of their department as a sort or
academic moonlighting. The report recommends that all
premises should be open to scrutiny. A distinction is drawn
between, on the one hand, NHS hospitals and university
departments, which should be inspected “where necessary
by or on behalf of the local ethics committee, and, on die
other hand, commercial institutions (including pharmaceu
tical companies) which “should” be subject to independtfit
scrutiny. Further, a register of approved commercial
institutions carrying out research on healthy volunteers £

THE LANCET, JUNE 7, 1986
Examples of apparent deception or lack of frankness listed
under category 4 touch the very heart of the demand for full
disclosure. Yet I believe most doctors would take the view
that patients should not be burdened with a serious diagnosis
which is merely probable or possible, if it does not affect the
current management.
Those in favour of patients’ having access to their medical
records argue that seeing these documents is in most
instances reassuring. I estimate that this would have been so
in approximately a third of the cases in the present series.
There is some evidence that reading the specialist’s advice to
stop smoking is more effective than merely hearing it. These
beneficial effects would, however, be appreciably reduced
once patients knew that the doctor realised that they would be
likely to read what he had written.
It is widely, though not universally, held that some medical
records contain information which should, in the patient’s
own interests, not be accessible. What is not sufficiently
appreciated is the high proportion of records to which this
reservation applies—at least in some specialties. In the
present sample, 42 out of 100 sets of notes contained at least
one comment likely to give rise to alarm or anxiety—an effect
which might persist despite explanation and reassurance.
Open access to medical records would profoundly affect the
specialist’s system of note-keeping. Besides having to develop
a plan for avoiding ambiguous or potentially worrying
symbols, he would be compelled to alter his hitherto frank
style. Where alarming or objectionable statements could not
be avoided, he would undoubtedly find some way of keeping
a second set of notes. Sensitive material would be
communicated to the GP verbally instead ofbeing committed
to writing, with the danger that it would be forgotten or
attached to the wrong patient.
Correcting misunderstandings and allaying fears fostered
by reading raw data couched in technical language would also
take more of the consultant’s (and presumably the general
practitioner’s) time. There would undoubtedly be a major
increase in cost to the NHS, both in paying for the additional
medical time and in arranging for the notes to be made
available to the patients under supervision. There would also
be a danger of defacement or loss.
The fundamental question is: What is best for the patient?
Medical science exists primarily for patients, not for doctors.
The answer surely is that the patient needs to have all the
information which would enable him or her to preserve or
restore his health to the maximum degree possible, and to
discharge his duties to his family and to society. The patient
should not be presented with information which is likely to
have the opposite effect.
CONCLUSION
I can appreciate that patients and potential patients want to
take greater responsibility for their own health, and they want
to have all the information available to enable them to do this.
This is right. They know that doctors sometimes fail to
provide them with important information and may make
inaccurate entries in their medical records. This is true. They
think that by insisting on seeing their records they would
avoid these problems. This is a mistake. Patients would be
overloaded with information, which their doctor would need
to explain—if he had time. More seriously, the notes and
letters in the record available to the patient would cease to be
frank.
What is needed is better record keeping and more time
spent in consultation with the patient; improved
communication in the traditional manner, rather than open
access to medical records. The findings of this small study
support the view that access to personal health data should be
limited to the disclosure of bare administrative details, such
as whether the inquirer is on a waiting list, and the name of
the consultant. Any patient who wanted to pursue the matter
further could then approach the consultant for more detailed
information.

Drugs and the Third World
DRUG MARKETING IN THE THIRD WORLD:
BENEATH THE COSMETIC REFORMS
Trisha Greenhalgh
Battle Hospital, Reading, Berkshire RG3 1AG
Eleven years ago Silverman and Lee, in Pills, Profits
and Politics, drew attention to the unethical marketing
tactics of certain US-based drug companies in Latin
America.1 Four years ago Dianna Melrose, in the
controversial Bitter Pills, claimed that western
multinational companies continued to make fat profits
from the “dumping” of harmful and therapeutically
useless drugs throughout the Third World.2 These and
other books have had impact, and standards of drug
marketing, as many would measure them, have risen.
However, from what I found during the four months
that I spent in India recently conducting a field study
into the prescribing practices of rural medical
practitioners3 the reforms in the drug industry seem to
have been a pyrrhic victory.
In India I introduced myself as “a foreign doctor
interested in diseases in this area” and followed 2400
patients through medical consultations. I recorded for
each patient the presenting complaint, the stated clinical
findings, and the drugs prescribed. In addition, I
collected promotional literature from medical journals
and drug company representatives, and sat in on
interviews between the representatives and local
doctors.
Examples of inexcusable marketing behaviour by
western-based companies can still be found. Merck
(India), in an advertisement that names Merck,
Darmstadt, West Germany, as its parent company,
promotes ‘Encephabol’ (pyritinol, a vitamin 8,
derivative) as a brain tonic that “improves the uptake
and utilisation of glucose in the brain”, and recommends
its use for “strokes, organic brain syndrome of the
elderly, post concussion syndrome, perinatal distress ■ • ■
(and) learning disorders”? I saw only two qualine“
doctors prescribe this drug—in both instances for 3
complaint of “weakness”—but I noted its unrestricted
sale over the counter in street pharmacies and bought it
THE LANCET, JUNE 7, 1986
myself from a market stall. Parke-Davis were still
promoting
the
anabolic
steroid
‘Adroyd’
(oxymetholone) for “underweight or asthenic patients,
convalescence from acute infectious diseases,... chronic
debilitating illness, osteoporosis, fractures, . . . (and)
decubitus ulcers”.4 I saw’ this product prescribed by
doctors for complaints of weakness, sore throat, and
fever.
Such aggressive promotion of useless and dangerous
drugs is indefensible, but I believe it is diminishing.
Only a handful of w’estem companies are still prepared
to risk their reputations in this way. However, this
practice is being replaced by a subtler one, whose effects
are more insidious, more widespread, and at least as
dangerous—namely, the inappropriate prescription of
drugs which are useful (even essential) in certain
circumstances but contraindicated in others.
Take the prescription of analgesics, for example. The
analgesic amidopyrine, its sodium sulphonate dipyrone
(analgin),
and
the
anti-inflammatory
drugs
phenylbutazone and oxyphenbutazone made up the
majority of both general practitioner prescriptions and
^^r-the-counter sales of analgesics in my study.
TTespite warnings on package inserts of the risk of fatal
blood dyscrasias, one or more of these drugs were given
to over 50% of patients requesting an analgesic.
European-based multinationals, including Hoechst,
Evans, Concept, Merck, and Glaxo (India), all obtain
considerable revenue from wide sales of these “second
line drugs”, even though (a cynic would say because)
their use has been severely restricted in the West.5,6
Chloramphenicol, whose use in the West is similarly
restricted, accounted for 11% of all antimicrobial
prescriptions in my study and was the commonest
antimicrobial sold without a prescription. Although
package inserts warning of the danger of aplastic
anaemia were supplied with each bottle, the practical
reality was, at best, that of a general practitioner
counting out loose tablets into an envelope and, at worst,
that of a pharmacist selling them over the counter one or
two at a time from an opened bottle. One pharmacist,
commended me on my interest in the package insert he
wras about to discard and explained, “This is legislation.
Government now approve to this drug”.
High-dose oestrogen-progesterone combination
^Bsparations have repeatedly been shown to be
teratogenic;7,8 in India they are allowed to be sold
specifically for dysfunctional uterine bleeding. Package
inserts warn that they should not be used in pregnancy.
Yet they continued to be prescribed as the cheapest and
most widely available pregnancy test in the country (I
never saw it prescribed for anything else), and I was sold
the drug at each of ten pharmacies where I requested a
pregnancy test.
'
A final example is the use of nutritional substitutes.
40 000 children in India still go blind every year because
the government cannot afford to fund a systematic
programme of vitamin A supplementation; yet over a
quarter of the country’s total drugs bill is spent on the
erratic and indiscriminate sale of vitamin and mineral
supplements. 729 such products are listed in the Indian
Pharmaceutical Guide, and they form the most
commonly prescribed class of drug in all the areas I
visited, accounting for 23% of all drugs dispensed.
General practitioners prescribed them for over half of all
patients, and many declared their belief that prescribed
1319
nutritional supplements were essential for health.
No-one can make a case for the banning of vitamin
syrups in a country where 90% of the children are at least
mildly malnourished, but to see vitamins in an expensive
form prescribed for children with the marasmus of raw
poverty begs the question: who takes responsibility for
their sales?
Phenylbutazone, chloramphenicol, and vitamin
supplements are useful and appropriate drugs in the
right clinical context. I prescribe them myself. And
tighter indications and sterner warnings are now' being
provided (ostensibly) to restrict their use. But the reality
is that these drugs continue to be used for trivial and
bizarre indications by doctors who have no real grasp of
their dangers and limitations.
Of the 26 general practitioners I interviewed not one
took seriously the possibility of fatal side-effects with
amidopyrine derivatives or chloramphenicol. Doctors
held the attitude that “if I prescribe it 30 times a day, and
it is freely available over the counter, it must be safe”. >_.
This attitude cannot be condoned, but it occurs in a
context where it cannot easily be condemned. The vast
majority of rural doctors work in conditions of extreme
material hardship and professional isolation. There is no
peer review, no clinical feedback, no system for
reporting or investigating adverse drug reactions, and no
access to independent information on the drugs they
prescribe.
Postgraduate
education
in
clinical
pharmacology is, for the rural doctor, the unchallenged
province of representatives from the pharnfaceutical
industry. Many representatives are paid only by
commission on the drugs they sell. The free samples and
financial incentives they liberally offer seem to be highly
effective in areas where the doctors themselves are living
well below' the poverty line. The representatives are, in
general, poorly informed of the indications for their
products, and often uninformed of serious side-effects.
Their sales techniques are simple—they generally show’
colour charts bearing pictures of the drug and a list of
indications in bold print. A flash-card from Glaxo
(India) states that “In DEBILITY and GENERAL
WEAKNESS, associated with tuberculosis, diabetes,
liver disease, cardiac disease, BECADEXAMIN (a
multivitamin/mineral supplement) helps healing,
promotes
growth,
restores
taste,
replenishes
deficiencies”. The verbal claims made by the
representatives surpass even such wide-ranging printed
texts, and the combination of eastern enthusiasm with
personal financial incentive adds a disturbing sincerity
to their affirmations. Far from being disdained by the
doctors, company representatives are welcomed w'ith
great ceremony as friends and fellow professionals in an
otherwise lonely subculture. I got the impression that
companies gained more sales through this curious
camaraderie than through any form of “promotion” in
the narrower sense.
In conclusion, the success of local and international
pressure groups in persuading multinational drug
companies to produce responsible advertisements and
comprehensive package inserts has been a pyrrhic
victory indeed. For some companies, the responsibility
which began with the package insert ends there, and
their directors have used the indications for which a drug
is now recommended as an official excuse for ignoring
the situations in which it is actually used. Cleverly
worded small print (in a language which most of the
1320
THE LANCET, JUNE 7, 1986
patients do not speak) provides the multinational
company with legal immunity and transfers the moral
accountability for drug deaths onto the poorly- informed
and professionally isolated Third World doctor, while
the dubious backstage behaviour of the company
representative is quietly ignored.
I have watched, in the slums of Calcutta, a young
mother spend two days’ wages on ‘Orabolin’ drops
(ethyloestrenol, an anabolic steroid), and feed the whole
bottle to marasmic twins through a rusty teaspoon. She
could not read a word of the warnings on the package
insert which I bought off her for a rupee, but she
responded to the picture of the healthy baby on the box.
Official legislation rarely can and almost never does
change realities such as these. India already has so many
cumbersome laws on the prescription and dispensing of
drugs that the government’s hands are consistently tied
by its own red tape trfid the administrative infrastructure
is pitiably inadequate for carrying out the volumes of
official instructions. I hope that I have shown that the
focus of reform must shift from the nitpicking of legal
loopholes to the reality of what is actually being
prescribed and dispensed, to whom and for what.
In Britain, no case of drug damage has gone as far as

Hospital Practice
THE FIVE-YEAR BURP SYNDROME
J. T. Wright
The London Hospital, Whitechapel, London El IBB
THERE is no argument about the cyclical nature of many
biological phenomena, such as sleep, ovulation, and
hibernation; that the higher functions of human beings are
also subject to cycles is, however, less evident—though well
accredited, for instance, in the manic-depressive psychoses
and in schizophrenic episodes. The somewhat fanciful urge
for a periodic change of sexual partner is, of course, the basis
for The Seven Year Itch, the 1950s film featuring Marilyn
Monroe at her best. Many years’ experience of the same
hospital outpatient clientele suggests that psychoneurotic
symptoms may also run in cycles. It is ff commonplace that
neurotic patients may change the focus'of illness from one
organ system to another with bewildering frequency. For the
purposes of this paper, however, I have selected patients with
recurrent gastrointestinal upsets in which the most common
symptoms are burping and the distension and discomfort that
proceed from this habit. Just a few of the patients included
have had recurrent cardiopulmonary symptoms such as chest
pain and overbreathing; their inclusion emphasises that the
syndrome described here is not after all specific to any body
system and that specialists in other fields will be perfectly
well acquainted with it.
THE PATIENTS
The patients studied were attending the London Hospital
outpatients department for the second time, at least two years
after the initial investigation. All were still complaining of
their initial symptoms, for which no organic cause was
evident. Patients reporting initially to another hospital and
then coming to the London Hospital for a second opinion are
not included. 43 patients (25 women, 18 men) are considered,
banned—it was voluntarily withdrawn following a
public outcry. It is time for another public outcry. It is
time the World Health Organisation gave financial and
scientific support for the continued education and
updating of Third World doctors in the difficult and
ever-changing subject of clinical pharmacology. It is
time the multinational drug industry stopped trumping
its ethical responsibilities with its commercial
obligations. And it is time the British Medical
Association had the courage to use its professional power
to demand that British-based drug companies be
morally accountable for the deaths their drugs have
caused in the Third World, .

35 being in the fourth to sixth decades of life at the time of
their first visit. Between them the patients paid 109 visits to
the outpatient clinic, 4 of them contributing four visits each
for the same symptoms at approximately 5-year intervals.
The table shows that 5 years was in fact the mode and also, by
elementary calculation, the mean interval between visits.
That the frequency of outpatient attendances was not due
to the whim of a small number of general practitioners is
attested by the fact that 46 GPs were involved and only 4
referred a patient more than once; it could, therefore, be
argued that subsequent referrals were more often due to a
change in general practitioner, though in most cases this was
another member of the same practice partnership.
DISCUSSION
What appears to the hospital clinician as a cyclical
phenomenon may be less evident as such to the referring
general practitioner, who in most cases will be aware that his
patient is prone to neurotic complaints. The common story
seems to be that following the first hospital investigation
reassurance so gained lasts for 2-3 years before confidence
wanes and symptoms become less tolerable. xMany patients
have the experience of a relative or friend being assured that
his or her symptoms were due to “nerves”, only to die of
cancer soon afterwards. Or the patient may express th?
feeling that symptoms “have gone on so long that surely
something (meaning cancer) might develop”.
The conscientious general practitioner will try reassurance
and symptomatic remedies for a further year or so and then,
yielding to pressure from patient or relatives and perhaps
with the feeling that 5 years is a decent interval, refer the
patient again. On the hospital side it is important to recognise
that such patients need explanation of their symptoms and
support, not reinvestigation.

i A First Report of Their Relation to Drug
Use With Special Reference to Analgesics
; in the thre
international Agranulocytosis and Aplastic Anemia Study
risks of agranulocytosis and aplastic anemia in relation to analgesic drug
9 use were evaluated in a population-based case-control study conducted in
Europe and Israel. Analgesic use in the week before the onset of illness was
compared between 221 cases of agranulocytosis and 1425 hospital controls.
'ar Analgesics significantly associated with agranulocytosis were dipyrone (metam-
col sodium), indomethacin, and butazones (phenylbutazone and oxyphenbutaul zone). For dipyrone, the rate ratio estimate was 23.7 in Ulm, West Germany,
i West Berlin, and Barcelona, Spain, and the estimated excess risk for any
exposure in a one-week period was 1.1 per million. In Israel and Budapest,
Hungary, where the rate ratio estimate was 0.8, there was no evidence of
zs| excess risk. In all of the regions combined, the rate ratio estimates were 8.9 for
i.!f; indomethacin and 3.8 for butazones, with excess risk estimates of 0.6 and 0.2
J- per million, respectively. Analgesic use 29 to 180 days before admission was
(compared between 113 cases of aplastic anemia and 1724 controls.

METHODS
This population-based case-control
study5 was originally organized in
Israel (population, 3.9 million), Barce
lona, Spain (4.1), Ulm, West Germany
(5.3), West Berlin (1.8), and Milan, Italy
(2.3). After a pilot phase, data collec
tion began on July 1, 1980. Three
additional regions joined subsequently:
Budapest, Hungary (2.0 million), in
December 1981, Sofia, Bulgaria (1.1), in
August 1982, and Stockholm/Uppsala,
Sweden (1.8), in January 1983.
Efforts were made to identify all
cases of agranulocytosis and aplastic
anemia that resulted in hospital admis
sion (community cases) or that oc
curred during a hospital stay (hospital
cases). To ascertain potential cases,
study centers maintained regular liai
son with all hospitals in the regions at
intervals of no more than two weeks.
The present report is based on cases
identified up to June 30, 1984.
Potential controls for community
cases of both agranulocytosis and
aplastic anemia were selected from
among other patients admitted to the
same hospitals at about the same time,
who were of the same sex and approxi
mately the same ages as the cases.
The controls for the hospital cases
were to have been a random sample of
all hospital patients5 who were not
receiving cancer chemotherapy, immu
notherapy. or radiotherapy. In practice,
such a sample could not be obtained,
principally because patients with seri
ous illnesses frequently were inaccessi
ble for interview. Therefore, hospital
cases were not included in the analysis
of the effects of drug use.
Specially trained nurses or physi
cians administered a standard ques
tionnaire to potential cases and con
trols. For young children, a parent or
guardian was interviewed. Detailed
information was obtained about drug
use, day by day for the first seven days
before admission, week by week for the
three weeks before that, anytime in the
five months before that, and anytime
in the more distant past.
To ensure that drug histories were as
complete as possible, patients were
first asked about indications. With
regard to analgesics, they were ques
tioned about use for pain, headache,
backache,
toothache,
menstrual
cramps, muscle relaxation, muscle

spasms, arthritis, gout, cough, colds,
influenza, and other infections. A list
of generic and trade names was then
read. The list was based on marketing
data for each region and included
names that together accounted for over
90% of the sales of the common non
narcotic analgesic drugs (there were
too many trade names to ask about the
remaining 10%) as well as other drugs
generally suspected of causing either
dyscrasia. To minimize memory loss
further, patients were not interviewed
if they had been in the hospital more
than 28 days.
Data collected on potential confound
ing factors included, in addition to
medication histories, demographic in
formation such as age and years of
education, medical information such as
major illnesses and history of allergy,
and limited information on exposure to
radiation, petrochemicals, laboratory
chemicals, insecticides, and benzene.
Information on the clinical course of
the illness was recorded for all subjects
(for agranulocytosis, this included sys
tematic questions on the time of onset
of sore throat, fever, and chills). In
addition, for all cases (including those
not interviewed), blood smears, bone
marrow aspirates, and biopsy sections
were obtained, whenever available. All
available blood cell counts were re
corded, together with other relevant
clinical and laboratory information.
Definition and Selection of
Cases of Agranulocytosis
Potential cases were patients with a
granulocyte count of 500/mm3 or less
(<O.5X1O9/L) or a total white blood
cell count of 3000/mm3 or less
(<3.0xl0a/L) who were not undergoing
cancer chemotherapy, radiation thera
py, or immunosuppressive therapy. A
lower age limit of 2 years was specified

because transient neutropenia in
younger children is commonly associ
ated with viral infections.7 There was
no upper age limit. The diagnoses of
potential cases were confirmed by a
committee of hematologists, who ex
amined the clinical and laboratory
data, including peripheral blood
smears, bone marrow aspirates, and
biopsy specimens. The review was car
ried out without knowledge of drug
use.
Final cases were patients with severe
selective neutropenia, defined as a
granulocyte count of 500/mm3 or less
(<0.5X109/L) with a hemoglobin level
of 10 g/dL or greater (>100 g/L) and a
platelet count of 100 000/mm3 or
greater (>100X109/L). Patients with
systemic diseases that can be associ
ated with neutropenia (eg, infectious
mononucleosis, systemic lupus erythe
matosus, leukemia, and malignant lym
phoma) were excluded. If a bone mar
row aspirate or biopsy specimen was
not available, the diagnosis was ac
cepted if the neutrophil count returned
to normal within 30 days (105 cases).
There were 422 final cases, of which
300 were community cases and 122
were hospital cases.
Because the major symptoms of
agranulocytosis—sore throat, fever,
chills, and headache—could each have
prompted the use of analgesic drugs,
there was a particular need for careful
timing of the day of clinical onset
(index day) of the illness, without
knowledge of drug use. The index day
was deemed to be the day on which
sore throat, fever, or chills first
occurred, as reported by the patient.
Of the 300 community cases, 47
(16%) were not interviewed for the
following reasons: death (7%), a delay
of more than 28 days (5%), psychologi
cal or medical reasons (3%), and fail
ure to locate the patient (0.3%). Among
the remaining 253 cases, there were sir
refusals (2%) and 39 (15%) for whom
the index day could not be determined,
leaving 208. Finally, 13 pilot cases with
an identifiable index day were also
included in the analysis of drug use,
giving a total of 221.
Definition and Selection of
Cases of Aplastic Anemia
Potential cases of aplastic anemia
were patients who were not undergoing
cancer chemotherapy, radiation thera
py, or immunosuppressive therapy and
who met at least two of the following
criteria: a white blood cell count of
3500/mm3 or less (<3.5X1OVL), plate
let count of 50 000/mm3 or less
(tgSOXlOVL), or hemoglobin value of
10.0 g/dL or less (<100 g/L) with a
reticulocyte count of 30 000/mm3 or t)
less (<30X109/L). As with agranulocy n
tosis, the diagnoses of potential cases ct
were confirmed, without knowledge of ae
drug use, by the committee of hematol th
ogists.
ft

who did not have neoplastic or granulo

it Calculated as a population-weighted average of the age- and sex-standardized region-specific rates
ated with the use of pyrazolones for 14
or more days was reported. In this
study, in Ulm, Berlin, and Barcelona
only one case and five controls who had
used dipyrone within one week of the
index day had taken the drug for 14 or
more consecutive days; in Israel and
Budapest the corresponding numbers
were five and ten (multivariate rate
ratio estimate, 2.2; 95% confidence
interval, 0.5 to 10.4). With regard to
other drugs, there were sufficient data
to examine 14 or more consecutive days
of use only for salicylates: there were
12 exposed cases and 24 exposed con
trols (multivariate rate ratio estimate,
2.9; 95% confidence interval, 12 to
7.1).
Estimates of excess risk were calcu
lated for those analgesics (dipyrone,
butazones, and indomethacin) for
which the lower 95% confidence limit,
based on a history of any use in the
week before the index day, was greater
than 1.0. For dipyrone use in Ulm,
Berlin, and Barcelona, the estimated
etiologic fraction was 27%, which
translated into an excess risk of 1.1 per
million. For butazone use in all regions
combined, the etiologic fraction was
4%, giving an excess risk estimate of
0.2 per million. For indomethacin use,
the etiologic fraction and excess risk
were 4% and 0.6 per million, respec
tively.
Aplastic Anemia
Table 6 gives the estimated incidence
rates by region. Stockholm/Uppsala is
omitted because bone marrow biopsies
are not done routinely in Sweden, and
many potential cases were not con
firmed due to insufficient information.
The overall annual incidence of aplastic
anemia was 2.2 per million (range, 0.6
to 3.1). Of the 168 cases, 159 were
followed up for two years: 78 had died,
giving a two-year fatality rate of 49%.
In Table 7 the distribution of
analgesic use in days 29 through 180 is
given for 113 cases and 1724 controls
according to use at any time in that
interval, use for at least four days in
any seven-day period, and use for four
or more days a week for at least four
weeks. Histories of any exposure to
indomethacin (multivariate rate ratio
estimate, 12.7), diclofenac sodium (8.8),
and butazones (8.7) were significantly
associated with aplastic anemia. In
addition, with limited numbers, the
rate ratio point estimates for the use of
indomethacin (52.0) and butazones
(34.5) were higher when the drugs had
been taken on four or more days in one
week and when such use had lasted at
least four weeks (49.9 and 43.4). For the
use of dipyrone, other pyrazolones, and
acetaminophen, there were no statisti
cally significant positive associations.
For the use of salicylates on four or
more days in any week, and for the use
of any drugs in the category of other
nonnarcotic analgesics, the estimates
were 2.9 and 2.2, respectively, but these
results were not statistically signifi
cant.
Excess risk estimates were calcu
lated for those drugs significantly asso
ciated with aplastic anemia (indometh
acin, diclofenac, and butazones) when
used any time in days 29 through 180

before admission. For indomethacin
the etiologic fraction of 6% translated
into an estimated excess risk for any
use in a five-month period of 10.1 per
million. For diclofenac, the correspond
ing estimates were 5% and 6.8 per
million, and for butazones they were
7% and 6.6 per million.
COMMENT
Agranulocytosis
The use of dipyrone was associated
with agranulocytosis in some of the
regions under study, but not in others.
Overall, indomethacin and butazones
were also associated with an increased
risk. In addition, there was an associa
tion of borderline significance for salic
ylate use, which was somewhat more
pronounced for use that lasted 14 or
' more days. There was no statistically
significant evidence of association for
pyrazolones other than dipyrone, acet
aminophen, or the heterogeneous cate
gory of newer nonnarcotic analgesics,
although for none of these drugs could
increases in risk of twofold to fourfold
be ruled out
The associations for dipyrone and
butazones were expected on the basis
of previous evidence.1-1'11’22 With regard
to indomethacin, however, although
there are case reports,23 there are no
studies that suggest an appreciable
increase in the risk of agranulocytosis.
With regard to salicylates, there are
only a few case reports suggesting that
they cause agranulocytosis,116251 and
since the statistical significance of the
association in this study is borderline,
it must be interpreted with caution.
The lack of association with the use

trols been restricted to those for whom
the index day was known beyond doubt
(trauma), the findings would not have
been changed materially.
There may have been information
bias, since it is widely known that
agranulocytosis can be caused by
drugs. Before the interviews for this
study were conducted, many of the
cases had been questioned repeatedly
about drug use. Thus, the memories of
the cases were stimulated before they
were interviewed while those of the
controls were not. Three approaches
were used to reduce information bias.
First, the patients were interviewed
within 28 days of admission. Second, a
standard and detailed questionnaire
was used. Third, three or more consec
utive days of drug use, presumably less
subject to differential recall, was ana
lyzed. Despite these precautions, infor
mation bias probably was not com
pletely avoided. Such bias is of concern
mainly for drugs already under suspi
cion as causes, such as dipyrone, and
would have resulted in overestimation
of the risk.
Information bias may partially ex
plain the regional variability of the
association with dipyrone use if the
intensity of questioning of the cases
before interview differed according to
study center. Another possibility is
that the recall of dipyrone use by the
controls varied among the regions. The
drug was available under many more
brand names in Ulm, Berlin, and Barcelona27-2, than in Israel2* and Buda
pest.21 Controls in Ulm, Berlin, and
Barcelona could have used dipyronecontaining preparations with unfamil
iar names and not have recalled their
use, with resultant overestimation of
the risk in those regions.
The possibility of underascertain
ment of analgesic use among the con
trols should be checked, if feasible, by
comparing the rates with data such as
defined daily doses.31
Potential confounding by age, sex,
region, concomitant drug use, and vari
ous other factors was controlled simul
taneously by multivariate analysis. It
remains possible that confounding was
incompletely controlled.
On balance, we judge that the results
are not materially biased. In particu
lar, the regional variability in the
association with dipyrone use is so
great that it is more plausible to
assume that some unidentified factor,
present in some regions, but not in
others, acts together with dipyrone to
increase the risk.
The excess risk for dipyrone use, as
estimated in this study, is discordant
with the findings of others. Discombe12
and Huguley'’ estimated, respectively,
that 0.867; and 0.79% of patients who
use aminopyrine for 1-1 or more days
develop agranulocytosis. Huguley sug
gested that this risk also applied to
dipyrone. As has already been pointed
out,32 these estimates were biased. Cor
responding estimates for dipyrone de
rived from the present data suggest
that in Ulm, Berlin, and Barcelona,
where the association was strongest,
the excess risk attendant to at least 14
consecutive days of use is 3.3 per
million, or 0.0003% (derived by multi
plying the excess risk by three,
because, as defined in this study, a
14-day period of use could have com
menced up to three weeks previously;
the assumption is made that the risk
per unit time is independent of the
duration of use). In the other regions,
the excess risk appears to be even
lower.
Bbttiger and Westerholm21 suggested
that agranulocytosis occurs in about
one of every 3000 dipyrone users. This
estimate is also much higher than the
present one, but its validity is in doubt.
First, there were repeated government
warnings about the dangers of dipy
rone, and it is possible that dipyroneassociated agranulocytosis was prefer
entially reported to the Swedish
Adverse Reaction Registry. Second,
and more important, the consumption
of dipyrone declined dramatically dur
ing the period of observation, and it
remained low thereafter, probably be
cause of the warnings. The denomina
tor of dipyrone users was estimated
from prescription records at a time
when consumption was virtually at its
lowest, whereas the numerator was
not, resulting in a risk estimate that
was too high.
Other studies have ruled out risks
for dipyrone users of more than one in
1000'“ and one in 133 00034 although
they did not provide estimates of the
actual risk.
With regard to indomethacin and
butazone use, the excess risk of agranu
locytosis has not previously been esti
mated. The data were too sparse to
explore possible regional variability for
these drugs.
Aplastic Anemia
The analgesics significantly associ
ated with aplastic anemia when taken
29 to 180 days previously were indo
methacin, diclofenac, and butazones,
with estimated increases in risk of the
order of tenfold. In addition, for two of
the drugs (indomethacin and buta
zones), with limited numbers, there
was a suggestion that the risk was
higher if they were taken regularly and
International Agranulocytosis and Aplastic Anemia Study

for a sustained period.
There was no evidence of an associa
tion with the use of dipyrone or other
pyrazolones. Within the latter catego
ry, however, numbers were too small to
evaluate individual drugs. For salicy
late use of four or more days’ duration,
the rate ratio estimate was somewhat
elevated, but this result could have
been due to chance. Similarly, the
association with the use of a mixed
group of the newer nonnarcotic analge
sics other than diclofenac could also
have been due to chance. However,
since individual drugs in this category
have been implicated in case reports as
possible causes of aplastic anemia,23
these agents require further study.
The butazones are a well-recognized
cause of aplastic anemia,20,35'36 and the
association identified in this study was
strong, although based on small num
bers. There have been case reports
linking indomethacin use with aplastic
anemia,23:n'B but the strength of the
association observed here is surprising.
Diclofenac has been implicated in case
reports,39 and the present study gives a
quantitative estimate of the risk. This
result needs to be confirmed in further
studies.
Potential methodological problems
must be considered. The diagnosis of
aplastic anemia is virtually inevitable
in all cases and selective enrollment
dependent on drug use was therefore
unlikely. The incidence reported here
was lower than in other studies,35,l°'11
but this could have been due to the use
of different diagnostic criteria. As for
the controls, their conditions, most of
recent onset, should have been inde
pendent of the use of analgesics 29 to
180 days earlier. Consonant with this,
the distributions of analgesic use
across diagnostic categories were simi
lar.
About 8% of the cases were not
interviewed because of death and 22%
because they could not be interviewed
within 28 days. If the use of any drug
was selectively associated with severe
or rapidly fatal aplastic anemia, this
could have resulted in underestimation
of the risk.
It was impossible to time the onset
of aplastic anemia because symptoms
such as fatigue or easy bruising are too
vague. In the days or weeks before
admission, episodes of infection or
fever due to as yet undiagnosed aplas
tic anemia could have provoked the use
of analgesic or antipyretic drugs. For
this reason, drug use that took place
within the 29 days before admission
was not analyzed. It must be acknowl
edged, however, that 29 days is an
arbitrary cutting point and that in
1756
JAMA.OcI3.1986-VoI256.no 13
some individuals the illness may have
remained undiagnosed for many
months. Thus, drug use that com
menced more than a month before
admission may sometimes have been
provoked by early symptoms and the
effects of some analgesics (eg, salicy
lates) could have been overestimated.
All of the results for aplastic anemia
must therefore be interpreted with
caution. However, for the use of indo
methacin, butazones, and diclofenac,
the rate ratio estimates were so high
that it is doubtful that they could be
entirely accounted for by occult aplas
tic anemia having provoked their use.
It is widely suspected that some
analgesics can cause aplastic anemia.
Butazones, for example, were given
considerable publicity while the study
was in progress. Had there been differ
ential recall, it should have been least
marked among those who used analge
sics the most. The associations with the
regular use of indomethacin and buta
zones for more than a month suggest
that information bias was not a major
problem.
As with agranulocytosis, confound
ing by concomitant drug.use and vari
ous other factors was controlled by
multivariate analysis. Again, it is pos
sible that confounding was incomplete
ly controlled.
This study is the first to provide
excess risk estimates of aplastic ane
mia in users of analgesic drugs. Their
interpretability is limited, however,
because of small numbers. In addition,
the present findings suggest that the
magnitude of the risk may be a func
tion of both the frequency and the
duration of use, at least for certain
drugs. How to select an appropriate
measure of risk is therefore unclear.
Given the uncertainties as to onset of
the disease and timing of relevant
exposure, we elected to estimate the
excess risks associated with use of a
given drug on one or more days in a
five-month period.
GENERAL CONCLUSIONS
In the regions in which this study
was conducted the incidence rates of
agranulocytosis and aplastic anemia
are low. Aplastic anemia is less com
mon than agranulocytosis, but the
fatality rate is higher. The fatalny
rates of the two diseases, as well as
their incidence, must be considered in
interpreting the results for analgesic
use. However, inferences about the
public health impact of analgesic use
cannot be more widely generalized to
other regions of the world if a fatal
outcome of agranulocytosis is more
common because of factors such as
malnutrition or inadequate medical
Set
care.

In considering public health implies
ME
tions, it is necessary to compare anal
gesics not only in terms of blow nez
dyscrasias, but also in terms of otha Ou
serious adverse effects. What matten
ultimately is the total risk of morbidity Rei
and mortality. Many of the conditions
that have been attributed to the use d
analgesics may occur more commonh Pub
than agranulocytosis or aplastic ane
mia. These include thrombocytopeni
purpura, hemolysis, shock, nephrotoi
icity, hepatotoxicity, and gastrointesti Med
nal disorders such as major uppe zneigastrointestinal tract bleeding. The lat

International Agranulocytosis and Aplastic Anemia Study
1757
Editorial
Analgesic Risks and Pharmacoepidemiology
Knowledge of uncommon adverse drug reactions ordinarily
derives from case reports based on clinical observations. Size
limitations of clinical trials preclude identification of rare
adverse reactions.1 Yet individual case reports have two
problems. First, an observed clinical event may be coinciden
tal to a particular drug exposure, be linked to the disease
being treated, or be due to other drugs. Only in the unusual
instance when rechallenge and reappearance of the event
are described can causality be clearly inferred from a case
report. Second, individual case reports cannot generally
provide a basis for incidence estimates.1 For prospective
clinical decisions, the issue is not whether a drug might
cause a reaction, but how often this happens.
See also p 1749.
Thus, the extraordinary study of the relationship between
analgesics and aplastic anemia and agranulocytosis in this
issue of The Journal is most welcome and important.2
Because these conditions are rare, a case-control study is the
only practical means to examine their epidemiologic charac
teristics and associations. To assemble 588 carefully defined
cases at 300 hospitals involved work in seven countries by
more than 40 investigators during a four-year period.
Patients and nearly 2000 controls were interviewed to
determine drug exposures and other risk and disease factors.
Effort was made to avoid bias in case and control selection
and data collection. This enormous study sought all cases in
a total defined population of 22.3 million so that reasonable
estimates of incidence could be derived.
The study found that agranulocytosis and aplastic anemia
are indeed rare conditions with overall annual incidence
rates of 6.2 and 2.2 per million population. For agranulocyto
sis, strongly positive associations were found for phenylbu
tazones, indomethacin, and dipyrone, but their excess risks
were small, ranging from 0.2 to 1.1 per million; Considerable
variation by region in the risk ratios for dipyrone was found
and discussed, but it remains unexplained and disturbing.
While the variation may be due to differences in populations
or medical practice, one must be concerned about hidden
biases or methodological problems that could affect other
results of the study. For aplastic anemia, excess risks of 6.6
to 10.1 per million were found for phenylbutazones, diclofen
ac sodium, and indomethacin, and increasing risk for
phenylbutazones and indomethacin was found with increas
ing intensity and duration of use. While the indomethacin
results are somewhat surprising, they are consistent with
evidence from an earlier study of aplastic anemia and
agranulocytosis done by Inman'1 in the United Kingdom.
Phenylbutazone risks appear to be lower than previously
found and thus merit critical examination. The relatively
low use rates during the period of the study for many newer
nonsteroidal antiinflammatory drugs prevented the drawing
of meaningful conclusions about the relationship of these
drugs to hematologic toxicity.
Why is this study important to the clinician? First, it
examines multiple drug exposures: too often only a single
drug is studied. If defined risks are to he clinically useful,

they must be available across a therapeutic drug class sc

that comparisons can be made. Next, though aplastic anemi flsSSsE
and agranulocytosis are rare effects of analgesics, benefit^JlAia
must always be weighed against quantified risks. Hematofc-J
logic toxicity is noted in labeling information for hundred®®?”
of drugs, yet because precise incidence data are seldo
available, clinical decisions about monitoring blood coundK£g£?
and use of drugs are based on intuitive perception of risk. K
Lest the study be misinterpreted, it must again br;

affected by analgesics than the hematologic system. Eve®ifc■
the highest rates found in the study do not greatly exceed
•.
mortality rate of five per million exposures for these drug£^®^,f
While no firm cutoff can be set for declaring any drtdSjtei';
absolutely safe, it should be recognized that when drudKgf. ■:
induced mortality is found to be below five or ten p«B&*
million, differential distinctions about the safety of one dnni^gar
compared with another will be difficult to ascertain arg/support scientifically. Thus, choices of analgesics, once
need for them is clear, should not be made solely on the basr??T;‘’of the hematologic toxicity described in this study.
The presentation of an impressive pharmacoepidemiology
study reminds us how few such studies are carried out. fl
examine risks of marketed drugs, appropriate cohorts fl
case series and comparison populations must be located ■
the community. Dealing with confounding by indication afl
other complexities of observational studies of ill patienfl
requires carefully designed approaches and sophisticate
analyses. Who will fund and conduct such studies? Usufl
sources of research support find that most pharmaceutiiij
safety issues are too mundane or are lacking in bas j
scientific significance. Regulatory bodies have few funds f W
research. The pharmaceutical industry, while not homog 1
neous, largely commits its postapproval research funds , "
clinical trials having potential for product enhancement. T, If
result is that there are few academic or industry-bas^
pharmacoepidemiologists in the United States or elsewhe®
There are no easy remedies for these funding and manpo»4|
deficiencies. Certainly the starting point is a recognitigl
that epidemiologic studies of postmarketing drug safety
in the interest of the medical community; the governntt h susceptibi
and the pharmaceutical industry. Drug development d
not stop when marketing begins. To improve drug thera
pharmacoepidemiology must be fostered and practiced.

Dr, A.Horxhedmer of Charing Cross Hospital
Medical School, UK and Dr. John YudJcin have pointed
oat that the study does not provide the trae incidence
of drug induced adranulocytosis, because w the study
excludes all patients Cap who die of agranulocytosis
without, receiving medical care, (b) who die of it
without having a white cell count and (a) who have
undiagnosed agranulocytosis and recover from it.,«S
Thus according to then the study would yield only a
•minimum estimate’ of both 8 incidence & morality*
while the ’actual incidence could be higher.
Dr. Willbert Bannenberg has pointed out many
other* limitations of this study-6.

It may bo mentioned that one of ths two chiefinvestigates and its study—director, Prof. M.Levy was

starts by claiming (on page No-1) that w °ipyrone is
widely used in many countries, including numerous
countries where medical knowledge and practice are well
advanced.” But it does not mention that it is banned
or withdrawn or severely restricted in developed countries
like s Australia, USA, UK, Greeae, Denmark, Norway,
Sweden, West Germany, Japan, In this paper, prof.
Levy likewise, selectively gives facts and figures
which favour the continued use of Analgin,
£jisi® 3 d Ing, j > rpp a-ga nd a s
Thus this so called Boston-Study is by no
means conclusive. Secondly, even the results of this
controvdrsial study ar*? being propagated by Hoechst in
a misleading manner, Hoechst claims that this study has
shown that the .risk of agranulocytosis due to Analgin
is only 1 in 1 million. It must be noted that this
risk of 1 in 1 million exists if one or more tablets
are taken in one week only, If dipyrons is ussd for
longer' periods, the risks will be greater, This was
confirmed by Shapiro, the epidemiologist and Admini
strative Director of this study, during the pressconference Ln Stockholm. Wilbert Bannenbergt7/has
estimated the risk ©S a^of 1 case of agranulocytosis
per 70000 packages of dipyrone—an estimate based on
the data of this Hocchsto-Study; but one which takes
into account the usual pattern of consumption of
analgin and hence is a more appropriate way of quoting
risk figures. LancQt has also pointed out. that ” The
estimate of the excess risk from dipyrone is expressed
rather oddly, as 1,1 per million takers during a seven
day interval. The calculation underlying this estimate
is not explained, The peculiar denominator is difficult
to apply to real life. The risk of exposure during
on® year could ba upto 50 times higher, It would be
expressed mor® clearly as the number of cases per
million defined daily doses (DDD) or per 100,000 packs
aold,""^®^ On 19th Oct’86, the Gernam Padcx'al Health
Office (BGA) conducted its second hearing on the risks
an3 benefits of dipyrone. In this hearing also the
present! ng of risks in the odd may of so many million
takers per week was criticized toy many scientists.
After expressing the risk in usual terms, the risk was
estimated to bejiin 30,000 to 1 in 70,000 per usor and
year. The speaker of the FRG*s Pharmacists Association
concluded that it took him a long time to understand that
the risk of agranulocytosis is as high as it was
_a
already estimated in the .1901 hearing.
Even if we accppt the controversialminimum
risk of agranulocytosis as given by this Hoechst-study,
we get 7000 cases of analgin-induced agranulocytosis
per year because every year, according to Hoechst, about
10000 tonnes of Analgin is consumed in the world, more
than 25 tonnes a day J, The mortality in agranulocytosis
in Europe, Eastern-bloc]: countries and third-world is
around 10%, 25% and 50% respectively. This means 1500 to
2000 deaths per year due to Analgin induced agranulo
cytosis 8!J^
Aqramilogytoals-ln Xndjat
Many medical practitioners say that they have
used plenty of analgin for years, but have not came
across a single case of agranulocytosis. This is because
of the fact that by and large, cases of agranulocytosis
go undetected in India. The clinical picture of agranu
locytosis abrupt onset of high fever, throat-pain,
rigors, occasional evidence of acute localized infectionis difficult to distinguish from that of infective fever,
so commonly found in India. The patient may recover
•spontaneously or die of fulminating infection, without
being investigated haematologically. Since the onset
of agranulocytosis is not immediate, it is hardly ever
suspected.
induced agranulocytosis does occur in
India,, One has to only look for it systematically.
i'his is what is being done, by Prof. B.C. Mehta., the
leading haema to legist from eombay. ,Je has communicated
his experience “ Xn my haematological-practiae,
X encounter 12-15 cases of agranulocytosis in a year.
Of these, 10-12 cases are caused by Dipyrone er Dipyrone
containing drugs.Dr.. Mehta has estimated that
even assuming the risk estimation of the Hoechst-study
to be correct? in India, one person develops Analgin—
induced agranulocytosis per day.

It has been argued by Prof. Levy (Adverse
drug reactions...op.Git.p.3 to 5) that Aspirin, also
causes death on a/c of its nephrotoxicity and by causing
acute gastrointestinal bleeding. But he conveniently
forgets that to a varying extent, all NSAIO# cause
nephropathy and gastric bleeding. (Gastric bleeding
is partly due :o the systemic effect of the anti
prostaglandin effect of NSAIDs and even injectable
Analgin can also cause gastiic bleeding?) Secondly,
the risk due aspirin induced gastric bleeding or
the risk, due to Peye’s Syndrome can be considerably
reduced by avoiding its use in susceptible patients,
whereas analgin induced agranulocytosis is unpredictable
and unpxeventable. Similarly accidental oc suicidal
poisoning due to paracetamol overdosage cancot be
compared to the risk associated with Analgin.

Dr, Shallgrajn, professor of Pharmacology, Grant Medical

About a second set of references provided by Hoechst,
L:'.r.of» ^haligx'am had this to say-—This is the most
unscientific of reviews. The author’s claim regarding
spasmolytic effect ( of dipyrone )’ is empirical and
l?cks details required for verifying the authenticity.
It. is no wonder, therefore# that none of the standard
textbooks of Pharmacology mention about any spasmolytic
action of dipyrone.
Some doctors feel that injectable Analgin
is necessary to reduce high fever. This is not true.
Oral aspirin# paracetamol and cold sponging is quite
effective. In case of hyperpyrexia# ice-cold sponging,
ice-cold enema, rehydration is more important than drugs?
hyperpyrexia can not be countered with anti-prostaglandin
effect of these drugs.
I! ■
Conclusion 3
///o have to conclude that since the risks
associated, with use of analgin are of very serious nature
and since there are now better substitutes available.
Analgin should. no more be used. That is why standard
authorities have, over a period of time, cast their
opinion against the continued use of Analgin. According
to the 5th edition of Goodman-Gillman, antipyrine, dipyrone
can be used in certain cases. Xn some cases of prolonged
intractable fever, as in Hoogkin*s disease and Periarteritis
nodosa, they are capable of controlling the disability and
<.'17
may be justified. "
Even in such cases they should be
employed only after safer drugs and other measures have
proven ineffective. They should be used under proper
supervision and monitoring, ^^he F.D.A. of U.S,, regards
that 11 true risk associated, with this drug farjany benefit
derived from its nee, including use in Hodgkin s disease
end similar malignant diseases.” ~"S The 7th edition (1985)

ANALGIN—A STUDY
1
F«a'R
L>
P
. The, Drug
A class of chemicals called PYRAZOLONES have been used
as medicines for over ninety years. Pyrazolones include
drugs like Antipyrine, Aminopyrine, Phenylbut'zone,
oxyphenbutazone, sulfinpyrazone and a derivative of
aminopyrine called dipyrone or analgin. The pyrazolones
share similar pain killing, fever reducing, inflammation
reducing and also toxic properties. Analgin being more water
soluble is amenable to use in injections and liquid oral
preparations (for children). They are rapidly absorbed in the
stomach and intestine and spread in various tissues of the
body in proportion to their water content. While 30 to 40%
of the drug is altered in the liver and eliminated in the urine
5% is eliminated unaltered. The fate of a significant fraction
is not known.
The range of actions of Pyrazolones is similar to that of
Salicylates (Aspirins) except in reducing fever in diseases
like Hodgkins disease and Periarteritis nodosa, whore aspirins
are not completely effective.
The most important and potentially fatal adverse effect
of Pyrazolones (Analgin) is Agranulocytosis. This is a
condition where the Granulocytes which form the major part
of the white blood cell population and are the first line
of the body's defence against infection are destroyed.
It is an allergic reaction and can occur suddenly even after
a fraction of a dose in any person who has been previously
taking Analgin with no bad effects. Within 6 to 24 hours,
the white blood cell count fall and granulocytes disappear
from the blood. They start reappearing 5 to 10 days after
the drug is discontinued and rapid recovery occurs.
The incidence of agranulocytosis has been variously estimated
from 0.01% to O.BS/o. If infection occurs now, it starts
as a sore throat of sudden onset, high fever and prostration,
which even on proper treatment carries a mortality of
20 to 50%.
The other adverse effects of Analgin documented in a study
are: skin rashes, dyspepsia, fever, analphylactic shock
and bronchospasm. Analgin can aggravate a bleeding tendency
and produces a serious fall in body temperature when given
along with Chlorpromazine. Liver cancer in mice has also
been reported by Japanese.

History and _present status
1897
Aminopyrine was first introduced and bec.ame very
popular in 1920s for pain killing and f-’ver. By 1930s
its use was world wide.
1922
Agranulocytosis was first described by U. Schulz
1922
Oipyrene or Analgin was introduced by Hoechst. Not
being recognised as a derivativa.of Aminopyrine,
it gained popular use.
1933
Madison and Squier established a causal relation
between Amidopyrine and agranulocytosis.
1935
Kracke and Parker established its relationship to
agranulocytosis beyond doubt
1938

The American Medical Association Registry on
Adverse Reactions recorded only 10 reports of
leucopenia (fall in UBC count) and none in children.
19601964
18 cases reported (7 children).
An increase in the import into USA of dipyrone
from nil in 1958 to 18,879 lbs in 1962 was noticed.
1964

19801904
An international study for agranulocytosis and
aplastic anaemia was done in Europe—called the
Boston Study, since coordination and data analysis uas
done at the Drug Epidemiology Unit at Boston.
This uas primarily financed by Hoechst, and the results
published in the JAMA of Oct 1986.
1983
The Government of India banned tho manufacture and
sale of Amidopyrine
1986
Malaysia banned dipyrone.
FRG banned DTC sale
In Netherlands, Dipyrone use is only allowed
for uncontrollable fever.
Following reports of anaphylactic shock, Italy, Egypt and
Saudi Arabia have prohibited manufacture of injectible
preparations.

sue s_
According to Hoechst, approximately 25 tonnes or
18.5 million doses of Novalgin. are used uorld wide
everyday. With most of the developed nations banning
or restricting its use, it is obvious that it is sold
mainly in third uorld countries.
The countries which have banned Dipyrone have been
managing pain without Dipyrone by using equally
effective and safe analgesics.

The 'Boston Study' generated a lot of controversy.
since Hoochs t used ths results even before publication
for a misleading advertisement campaign showing the
occurrence to ba 1 per million. The hearing of
the German Federal
Health Office finally confirmed
the assumption of 1 per 30,000 to 60,000 to be
nearer the mark, or one tablet per 70,000 consumed
could cause agranulocytosis based on this same study.
The limitations of this study are that—
a.
it excludes all patients
i.
who die of agranulocytosis without
receiving medical aid;
ii.
who die without having a white cell count; and
who
iii.
have undiagnosed agranulocytosis and
recover from it.
iii.
b.
it does not look into other side effects
of dipyrone, like shock, fall in BP, Urticaria
etc.
c.
the data presented in the intermediate and final
reports are inconsistant
d.
whereas 400 cases of agranulocytosis were
registered to a sess risk properly, only 221
cases were analysed in the final report; "
e.
thare is extreme variability in data between
different countries and aven within the same
country; and
f.
some data wore seen to be clearly unreliable.

The findings of the controversial 'Boston Study' is being
utilised by Hoechst the largest manufacturer of.
Analgin for sales promotion in Germany, Eastern Bloc
countries and the Third World.' Unethical propaganda
practices with diff rent types of promotional literature
in different countries is being practiced. Even claims
of anti-spasmodic action which is not scientifically
substantiated is being made. Any source of detailed
scientific literature is virtually non-existant beyond
the literature supplied by the drug companies.

iv.
Since 1985, Dipyrone (Analgin) has not found mention
in any standard medical text books, except for naming
it as a drug which can causo agranulocytosis.
v.
Even in our country, medical student' do not learn
about analgin while doing their Pharmacology.
4 • JLD_JLCLE!A.€L
i.
In 1983, the Government of India banned the manufacture
and sale of amidopyrine- but not dipyrone. The Drugs
Consultative Committee had recommended ban on FDCs
of dipyrone also but this seems to have'slipped from
the banned list.
ii.
The government is the largest manufacturer of dipyrone
in this country.
iii.
Analgin is among the largest selling analgesics in the
country with sales figures accounting for Rs 70 million.
There are approximately 200 formulations containing
Analgin, including injoctibles and drops for newborns
and infants for colic.
iv.
Analgin is available as OTC in spite of its being a
Schedule H druo in our country and the attitude of
the proscribing doctors as per a study (Lancet 86)
was "if I prescribe it 30 times a day and it is
available over the counter, it mi st be safe,". In a
field study (Lancet 86) it was seen that the pyfzolones
made up the majority of both GP prescriptions and OTC
salas of analgesics. One more of these drugs were given
to over 50% of patients requesting an analgesic.
v-
Drug action groups have initiated a campaign on Analgin
especially at ACASH, Bombay, OAF-West Bengal and AIDAN,
Neu Delhi.
vi.
Analgin induced agranulocytosis does occur in India,
especially if one looks for it systematically as a
Bombay haematologist BC Mahta has done. He reports
12-15 cases of agranulocytosis a year, of which 10-12
are caused by Dipyrone or Dipyrone containing drugs.
Evan by the risk estimation of .the Boston Study, in
India, one person develops analgin induced agranulocytosis
per day by other reasonable estimates, it could be
15 times this figure.

5. Mider Issues
Doveloping countries like ours arc ill placed to afford
expensive and useless health care products and definitely
not the frankly dangerous ones.
Me have unsophisticated consumers and poorly developed
regulatory and advisory systems—this is fertile ground
for pharmaceutical companies to indulge in unacceptable
practices .
The vast majority of rural doctors working in professional
isolation have no access to independent information on
drugs they prescribe. Here, the representative of the
,
pharmaceutical company who is ill-informed himself and
paid by commission on drug sales becomes an id -al tool to
promote the interests of the Pharmaceutical company.
Thus, it appears that the consumer is at the mercy of drug
manufacturers. Other than an appeal to the Food and Drugs
Administration
the Central Government and ths MRTP
Commission the consumer is virtually without recourse to
any independent body such as tho judiciary. The 03 Hospital
Commission (Lentin Commission) enquiry reveals the ineffective
ness of those agencies. The Consumer Protection Act of 1986 is
expected to offer some hope.
In effect only a public outcry by the consumer can force
voluntary withdrawal by or reform by drug companies.

on the

Experiments
were
carried
out in vivo and in vitro on white rats and
it
was established that analgin, aminton and analgeton stimulated the
release
of
beta-endorphin,
affecting
various regulatory levels.
Analgeton
in
contrast
to
analgin showed longer analgetic effect in

wasteful abundance while drugs
for leprosy and tuberculosis (two

★ Escalating Prices
Price control policies have been
both inadequate and ineffective
and hence the cos. of drugs has
been constantly escalating. With
liberalization policies of the pre
sent government this is bound to
increase further. The purchasing
power of majority of our patients
is limited. With increasing prices,
patients are forced to buy only
part of a prescription or go in for
sub-standard alternatives pro
moted by the drug shops.

There was a time not so long ago
when the doctors' profession
was a vocation. Aspirants to the
profession saw service to the
sick and ailing as more important
than the financial rewards they
would get, if at all, from their
grateful patients. Today the
situation has changed drastically.
Parents are willing to pay lakhs to
get their children into medical
school. No such investment
would be made if the returns
were not equally rewarding. Aspi

consumers is the absence of
awareness of drug use, mis
use and the effects of over

next to absent in India. Due to
loopholes in the existing laws,
precautionary product infor

medical products. The media,
the medical profession, the
educational system and the
social welfare agencies con
centrate on the misuse of
psychotropic substances and
drug abuse. Misuse, overuse

DRUG POLICIES - GOVERNMENT OF INCIA 1978
The Hath! Committee Report
The Government of India set up on February 8, 1974 a
Committee under the Chairmanship of Shri Jaiskhlal Hathi ano
other members of Parliament along with various officials and
non-officials, to enquire into the various facts of the crug
Industry in India.
The Hathi Committee submitted its report to Government
in April 1975. The Eport was laid on the tables of both houses
of Parliament in May 1975. /vfter several inter ministeral
discussion, and discussions with representatives of drug industry,
the views of the cabinet committee was put in February 1977, but
could not be considered. Final decisions of Government based on thereports were made on 29th March 1978.
Broad objects of the 'New Drug Policy
(i) To develop self-reliance in drug technology;
(ii) To provide a leadership role of the public sector;
(iii) To aim at q ..ick self-sufficiency in the ourput
of drugs with a view to reduce the quantum of
import s;
(iv) To foster and encourage the growth of the Indian
sector;
'
(v) To ensure that the drugs are available in abundance
in the country to meet the health needs of our people;
(vi) To make drugs available at reasonable prices;
(vii) To keep a careful watch on the quality of production
and prevent adulteration and mal-practices;
(viii) To offer special incentives tO' firms which are
engaged irz Research and Development; and
(ix) To provide other parameters to control, regulate
and rejuvenate this industry as a whole, with parti
cular reference to containing and channelizing the
activity of foreign companies in accord with national
objectives and priorities.
The new drug policy aims at promoting the Indian Drug
Industry. At first the Hathi Committee also recommended that the
Multinationals should be taken up by Government, however, since this
was a drastic change, this view was not adopted.
If nationalisation
takes place Government would also take over Indian companies above
a certain size. Certain stringencies were, however, laid down with

PLUG POLICIES - GOVERNMENT OF INDIA 1978
The Hathi Committee- Report
The Government of India set up on February 8, 1974 a
Committee under the Chairmanship of Shri Jaiskhlal Hathi ano
other members of Parliament along with various officials and
non-officials, to enquire into the various facts of the crug
Industry in India.
The Hathi Committee' submitted its report to Government
in April 1975. The Eport was laid on the tables of both houses
of Parliament in May 1975. Zvfter several inter ministeral
discussion, and discussions with representatives of drug industry,
the views of the cabinet committee was put in February 1977, but
could not be considered. Final decisions of Government based on the'
reports were made on 29th March 1978.
Broad objects of the 'New Drug Policy
(i) To develop self-reliance in drug technology;
(ii) To provide a leadership role of the public sector;
(iii) To aim at q..ick self-sufficiency in the ourput
of drugs with a view to reduce the quantum of
imports;
(iv) To foster and encourage the growth of the Indian
sector;
’
(v) To ensure that the drugs are available in abundance
in the country to meet the health needs of our people;
(vi) To make drugs available at reasonable prices;
(viij To keep a careful watch on the quality of production
and prevent adulteration and mal-practices;
(viii) To offer special incentives to' firms which are
engaged it/ Research and Development; and
(ix) To provide other parameters to control, regulate
and rejuvenate this industry as a whole, with parti
cular reference to containing and channelizing the
activity of foreign companies in accord with national
objectives and priorities.
The new drug policy aims at promoting the Indian Drug
Industry. At first the Hathi Committee also recommended that the
Multinationals should be taken up by Government, however, since this
was a drastic change, this view was not adopted. If nationalisation
takes place Government would also take over Indian companies above
a certain size. Certain stringencies were, however, laid down with
regaro to foreign companies like Small Scale Sector will be a
prombitec area, formulation licences for foreign companies will be
given only if they.are linked with the production of ohioh technology

Another important policy adopted was with regard to Brand

The Drug Industry in India—
What our experts say
The Industry
Pattern of Prescribing
The total output of’the industry increased
hundredfold-from Rs. 100 million in 1947
to Rs. 10,500 million in 1978-79. This was
due to expanded production, especially of
an ever-increasing number of sophisticated
drugs, and rising prices...
One of the most distressing aspects of the
present health situation in India is the habit
of doctors to over-prescribe glamorous and
costly drugs with limited medical potential.
It is also unfortunate that the drug producers
always try to push doctors into using their
products by all means—fair or foul. These
basic facts are more responsible for distortions in drug production and consumption
than anything else.
The drug industry has enjoyed a higher
man-average profitability so that investment
therein has increased substantially from
Rs. 240 million in 1952 to Rs. 4,500 million
in 1977.
There are about 125 large and medium
factories and nearly 3, 000 small scale sector
units engaged in this industry which pro
vides
employment to
about 100,000
workers.
Pattern of Drug Production
There is now an overproduction of drugs
(often very costly) meant for the rich and the
well-to-do while the drugs needed by the
poor people (and these must be cheap) are
not adequately available. This skewed pat
tern of drug production is in keeping with
our inequitous social structure which stresses
the production of luxury goods for the rich
at the cost of the basic needs of the poor.
Out of a total production of Rs. 700
crores in 1976, 25 percent is taken away by
vitamins, tonics, health restoratives and enzy
me digestants, mostly consumed by the
relatively well-fed urban population. Twenty
percent is covered by antibiotics, only 1.3
percent by sulphonamides (a very cheap and
useful anti-infective) and 1.4 percent by anti
tuberculosis drugs...
6
Structure of the Industry
The existing drug policy rightly emphasi
ses the attainment of self-sufficiency in the
production of drugs, in increasing the share
of the Indian producers and in giving a more
significant role to public sector.
The foreign companies account for about
40 percent of the total drug production in
the country; their share in the production of
basic drugs was about 28 percent and that in
formulations, 44 percent (1978-79). This is
still high.
Price Control
The drug prices are high and continue to
rise. In some instances, Indian prices are
even higher than the international ones.
Packaging increases the cost of drugs
very greatly because the trend is to make it
attractive and highly elegant and to add
cosmetic embellishments to promote sales...
There may indeed be a glut of applications
for the introduction of 'Me-too Drugs' which
will not attract new legislation for another
five years in regard to price control...
Medical Service
Genuine
'breakthrough'
declined in recent times.
research
has
Existing prices of drugs including those
of essential drugs of everyday use is highly
inflated. For example, the cost of analgin
sold over the counter is 30 times the cost of
production.
Prices are often inflated by the use of
brand names.
Very often, prolonged controversy over
the price of a drug has resulted in stopping
its production.
The bill for import of bulk drugs, inter
mediates, solvents etc., has jumped from
Rs. 53.77 crores in 1976-77 to about Rs. 119
crores in 1979-80.
Quality Control
The standards prescribed are unrealistic...
are mechanically copied from books., and not
uniformly enforced in all parts of the country.
Consumption of Drugs
At present the supplies of drugs to urban
and rural institutions within the health care
system is very uneven. In an urban hospital,
for instance, the drug cost is Rs. 6 per patient
October-November 1984
per year while in a Primary Health Centre, it
is about 40 paise per patient per year.
An Overview
We recognise the value and significance
of drugs in the health care system. We fully
support the policy that all the essential drugs
should be produced in the country, preferably
in the Indian sector, and that they should be
made available to the people at reasonable
prices. To realize these objectives, it is
essential to lay down and vigorously imple
ment a national drug policy which will
ensure that the pattern of drug production in
the country (barring drugs meant for export)
should be geared to its actual needs. While
the supply of drugs should be adequate,
eternal vigilance is required to ensure that
the health care system does not get medicalized, that the doctor-drug-producer axis
does not exploit the people, and that the
'abundance' of drugs does not become a
vested interest in ill-healthSource :

Big business The production and
marketing of modern medicines is
one of the biggest, most profitable
business in the world. Drug compa
nies are continually inventing new
products to increase their sales and
profits. Some of these medicines
are useful. But
atleast 90% of

them and people buy them, because
the drug companies spend millions
on advertising.
False advertising
Especially in
poor countries, much of the adver
tising, and even the information
published in 'pharmaceutical indexes',
is misleading or false. Information
on dangerous side effects is often
not included. Risky medicines are
frequently recommended for illnesses
less dangerous than the medicines.
(For example chloramphenicol has
often been advertised as a treatment
for minor diarrhoea and respiratory
infections).
Dumping
Drug
companies
in
wealthy countries sometimes produce
medicines that do not sell well in their
homelands. Or the use of certain
medicines is restricted or prohibited
because they have been proved un
safe. It is a common practice for
drug companies to ‘dump' these
medicines on poor countries—often
with a great deal of false advertising.
For example, several years ago the
U.S. government restricted the use
of Lincocin (lincomycin) because
Lack of adequate controls. Poor
countries, especially, have inadequate
laws controlling the production and
sale of medicines. As a result, many
poor countries sell up to 3 times as
many different medicines as rich
countries do. Most of these medi
cines are a waste of money. Many
are completely unreasonable combi
nations of drugs, yet they are widely
prescribed by doctors. For example,
in both Latin America and Asia, a
popular injectable medicine is tetra
cycline combined with chlorampheni
col. This is a senseless combination
because the two drugs are 'incom
patible' and should never be used
together.

cines well, so they follow the patterns
set by doctors. Unfortunately, this
often leads to incorrect use.
For
example, in Latin America atleast
95% of doctors, prescriptions for
Vitamin Bn injections are among the
most widely used self-prescribed
medicines in Latin America—at a cost
of millions to a people too poor to
eat well!
8.
Health Workers not adequately
informed In spite of the tremen
dous amount of self-medication in
most
countries, many programs
still do not teach health workers
much about the use—or misuse—of
commonly self-prescribed medicines.
As a result, many health workers to
meet popular demand, secretly pur
chase and administer a wide range of
medicines they know little about.
People not adequately informed.
Neither doctors nor the people are
adequately
informed
about
the
correct use of medicines. Most
doctors rely on the information given
in misleading 'blurbs' supplied with
sample medicines, while villagers
who self-prescribe often receive no
information at all. In Mexico, for
example, upto 70% of prescription
drugs are sold without prescription.
Yet the packaging of these medicines
generally contains no information
about use, dosage, or risks.
9.
Use of medicine to gain prestige
and
power. Another reason for
medicine overuse is that many pro
fessionals use their ability to medicate
as a sort of magic to make people
grateful and dependent. This way
they gain special privilege and power.
In the same way. health workers
may be tempted to give injections
or expensive drugs when home
remedies or kindly advice would cost
less and do more good.

Medication as a Substitute for Caring

use of medicines, however, is that doctors

doctor or health worker. They like to believe
that "there is a medicine for everything".
They are disappointed if the doctor or health
worker does not give them any, even when
medicines will do no good and the health
worker carefully explains why.
However, many doctors
and health
workers get into tne habit of giving everyone
medicine—for any and every problem they
have. The less curable the problem, the
more medicines they give!
So a 'vicious circle' results in which the
doctor always gives medicine because the
'patient' always expects (or demands) it,
because the doctor always gives it. The
prescribing of a medicine becomes both
the symbol and the substitute for
human caring. This problem especially
common in places where doctors, nurses, and
health workers are overworked. The result
is not only a costly overuse of medicine, but
a failure to meet human needs on human
terms.
At the same time, people have come to

The Crazy World of Tonics
Mukarram Bhagat
'Health' tonics are a craze with the afflu
ent in the cities with their supposedly hectic,
energy-consuming life-styles. Feeling tired?
Pop a pill or gulp down a spoonful and it will
keep you going (nobody knows where!)
The most commonly used tonics are
multi-vitamin preparations with highly exce
ssive quantities of vitamins.
Incremin C, the famous growth tonic with
the Giraffe logo, contains an important amino
acid lysine which the human body cannot
synthesise by itself. However, a teaspoon
of Incremin contains only about 300 millig
rams of lysine when just a handful of peas
contains about 1800 milligrams of lysine.
The advertising slogan that Incremin turns
"extra eating into extra growth" is medically
unsubstantiated and at best a half-truth.
The quantities of vitamin constituents of
Incremen are absurd: 10 times more vitamin
B1, 25 times more vitamin B12, 2 times
more vitamin B6 than required by the body
daily. (1)
The daily requirement of the human body
of vitamin C is about 50 milligrams, of
vitamin B1 one milligram and some others
in minute quantities of a few micrograms.
Against these well established norms, most
tonic preparations contain between 10 to 50
times the minimum requirements (2) which
are simply excreted away by the body—a
colossal waste of valuable nutrients in a poor
country. Further, most vitamins are needed
in small amounts to stimulate the processes
of normal metabolism, they are not energy
giving in themselves.
28
It is almost certain that the high-potency
multivitamin formulations consumed by the
well-fed are almost wholly rejected by the
body. For example, the daily requirements
of vitamin C can be obtained from a single
fruit or a salad helping. Vitamin A, supplied
by green, leafy vegetables, is stored in large
amounts by the body for proper vision.
Vitamin D is naturally synthesised by the
skin from daily sunlight. Despite all these
simple facts, the craze for 'health' tonics
continue unabated. (2).
Why ? Manohar S Kamath in his article
in THE DAILY MAGAZINE provide the ans
wers :
"The real culprits behind the 'tonic craze'
are the manufacturers of such formula
tions. The principal reason for their hard
selling of such products that the tonics
and vitamins fell in 'category four' of the
Drugs Price Control Act, which means
that there is no limit on profits made on
these preparations. With easy pickings and
a readymade market, no wonder then that
every new company entering the pharma
ceutical world wants to market its own
brand of tonic rather than any life-saving
drug;" (2)
Explaining how the 'tonic craze' is the
result of systematic campaigns of the large
companies, . ie says :
"The first part of the plan was the mount
ing of an intensive sales campaign to
influence doctors on the need for tonics
in their day to day practice. This was
followed by free sampling" (2)
Medical Service
"The other part of the marketing gimmic
kry in selling tonics was by directly adver
tising in the mass media, to catcl the
public eye. Slogans like "Do you feel tired
at the end of the day? You need..." or "A
woman needs iron every day" gradually
made a deep impact on the people until
many were psyched into believing that
they could not do without a tonic."(2)
Waterbury's Yellow Label Tonic, a
brand leader in the Indian tonics markets,
contains only 3 milligrams of iron per teas
poon just 1/10 of which may be absorbed
by the body. The Indian Council of ledical
Research (ICMR) recommends at least 10
milligrams for women. The producer claims
that this tonic stimulates appetites and builds
bodies. But chemical analysis has revealed
that it has 10% alcohol content which is the
real appetite-stimulant : (1),
We have noted that these tonics are not
consumed by the poor but mainly by the
relatively rich whose ordinary diet adequately
meets their vitamin and other requirements.
In recent years,'evidence has grown that the
excessive vitamins may not simply be dis
charged by the body but may even cause
severe disorders. Prolonged consumption of
excessive vitamin C may form kidney stones,
excessive vitamin A may cause diseases of
the hair, skin and liver and vitamin D in
excess may cause disorders of the kindneys
and bones. (2)
Take this further example from South East
Asia. In the U K„ Sanatogen is marketed
as a 'nerve tonic' for old women who
believe in its doubtful ability to tranquilise. But Sanatogen Powder is marketed to
stuaents in Malaysia who believe in its
ability to stimulate their minds. "Worried
about exams?" says the advertisement. San
atogen will give you "Greater energy and
concentration". Can a drug both stimulate
and sedate? (3)
A person who eats well does not need extra vitamins.
THE BEST WAY TO GET VITAMINS:
Thus, the sheer irrationality and deliber
ate exploitation of consumers through this
sinister "tonic racket" is obvious. The fact
that many such, rackets' continue unabated
is a measure of the enormous influence and
power of the large pharmaceutical corporat
ions not only in India but in many other
countries, particularly the developing ones.
More than 20 years ago, the following
words were spoken before the Kefauver
Committee hearings on drugs in the U.S.A.:
"The incidence of disease cannot be
manipulated and so increased sales volume
must depend atleast in part on the use of
drugs unrelated to their utility or need, or in
other words, improperly prescribed. Human
frailty can be manipulated and exploited and
this is fertile ground for any one who wishes

to increase profits. The enormous sales of socalled tranquillisers are only a small part of
the crop reaped from this ground. The phar
maceutical industry is unique in that it can
make exploitation appear a noble purpose "

To frustrate the move (i.e„
introduction of schedule X)
owners of the retail drug shops
under the leadership of their pow
erful Association had protested
by closing their shops for three
days and subsequently many of
them stopped storing drugs under
Schedule X (even such essential
drug like phenobarbitone to the
great inconvenience of millions of
epileptic patients!). The only plea of
the shop owners being that the
introduction of this schedule
would increase their clerical
burden as they have to maintain
proper inventory. Their plea
seems to lack substance in as
much as legally drugshop owners
are supposed to keep inventories
of all items of prescription drugs
coming under different other
schedules. Could it be that their
real difficulty lies elsewhere? It is
wellknown that majority of the
drugshops in our country are run
without a qualified staff (i.e., a
pharmacist) Only a pharmacist is
eligible to record his signatures on
the prescriptions while dispensing
a drug under Schedule X as
required by the Rule.

Reporting in 1956 on the excessive amount of space taken up by advertisements in

"The largest field of

by law is of drugs and proprietary medicines
The volume of advertising of such
commodities ranks next only to the volume of advertising of cosmetics.

Consumer Alert - Consumer Action
Ravi Narayan
The Problem
The Indian Council of Medical Research
(ICMR) and the Indian Council of Social
Science Research (ICSSR) have, in a joint
study group report entitled "Health for All —
an Alternative Strategy" warned that 'eternal
vigilance is required to ensure that the
health care system does not get medicalised,
that the doctor-drug producer axis does not
exploit the people and that the abundance
of drugs does not become a vested interest
in ill-health'. This warning is a serious
indictment of the drug industry and the
medical profession in the country. It con
firms the growing evidence that drugs are
being pushed on an unsuspecting public by
devious methods which masquerade as
'sales promotion' of drug companies and
'professional prescribing practice' by doctors.
A spate of reports have been appearing
in our newspapers and periodicals of late,
on drug related issues and a review of these
highlight that many of the following practices
are not at all uncommon in India.
(i) Sale of drugs banned in other
countries eg: Lomotil and Clioquinol
preparations.
(v)
Promotion of drugs for indications
that are not clinically proved and are
often
potentially
dangerous
eg:
Promotion of EP forte combinations
for pregnancy testing and induction
of abortion. There is well documented
scientific evidence that risk of foetal
deformity is increased by the use of
these hormonal preparations.
(vi)
Sale of spurious, adulterated or poor
quality drugs eg: Turmeric powder in
tetracycline capsules and poor quality
and reaction producing intravenous
fluid preparations have been reported.
(vii)
Sale of old, expired and unused
drugs. There is the double danger
of effects of denatured drugs as also
of inadequate dosage.
(viii)
Over-prescription and
misuse of
tonics, high protein foods, hormonal
preparations and baby foods that
are both superfluous and a drain on
the family economy.
(ix)
Production of drugs for profits rather
than health needs of people eg: The
ICMR/ICSSR report highlights that
drugs for diseases like leprosy and
tuberculosis which affect millions
are produced at one third and one
fourth of the actual requirements
while tonics, vitamins and high
protein substitutes are being prod
uced in wasteful abundance.
(x)
Sale of drugs over the counter with
out doctors' prescriptions or the
necessary statutory checks.
(i) Sale of irrational combinations and
formulations eg: Hathi Committee has
suggested weeding out of atleast 23
such preparations.
(iii)
Sale of drugs without adequate pre
cautionary product information.
(iv)
Sale of drugs at highly inflated costs
eg: it is reported that Analgin is
being sold at 20 to 30 times the cost
of production.
October -November

It is evident then that what is needed in
the country today is a consumer awakening
and awareness building process that will
sensitise people to the realities of the drug
industry, mobilise public opinion, sensitise
policy makers, confront the medical esta
blishment and challenge the drug industry.
This process’ will have to the initiation,
promotion
and sustenance of consumer
action to ensure that the drug policy in India
is more 'people' and 'health' oriented. Is
there any evidence of such an awareness ?
Consumer alert and action
Beginning in the late seventies, there is
an increasing number of organisations,
associations, projects and action
groups
who have begun to create an awareness of
drug-related policy issues.
These groups
are predominantly if not exclusively urban
based, consisting of young professionals and
intellectuals
from
different
ideological
backgrounds.
Since the Medical Profession is the
'instrumental consumer' ie., they prescribe
the drugs, many of these groups have
directed their efforts particularly towards
them. Many others are health or develop
ment
associations,
science popularising
movements and consumer associations who
are increasingly taking up drug-issues as one
of their many activities.
The main types of action they have been
involved in are :—
1.

DAN meets twice a year to plan and
coordinate its activities.
Towards a People's Movement
All the above efforts are small steps to
wards a much more wide based consumer
movement against drug u^e and abuse and
profit oriented drug policies. However, it must
be remembered that in a country like ours
when a very large percentage of people are
below the poverty line and when more than
75 percent of the people have little access to
basic health science a consumer action pro
gramme only on drug matters will continue
to be cut off from the needs and aspirations
of the majority.
Dr Norman Bethune, Famous for his work
in China, wrote ‘The best form of providing
health care and health protection would be to
change the economic system whica produces
ill health-to liquidate ignorance, poverty and
unemployment'.
One hopes that eventually drug related
issues will become part of a much wider
people's campaign for health, development
and socio-political change because at the
root of the entire problem of drug production
and availability lies what Ivan lllich has aptly
described as ‘Social-iatrogenesis-ie., health
policies reinforcing an industrial organisation
which generates ill-health'.

Medical Service
Drug Utilisation Survey Report
This survey was conducted by the National Institute of Nutrition
(NiN) in cooperation with the Dir ctorate of Drug Control Administration
and AP Chemists and Druggists Association, Hyderabad in the
twin cities of Hyderabad and Secunderabad covering 10% of the 3 30
retail pharmaceutical shops.
Some of the findings of the survey are as follows:
—
self medication rate was an alarming 46%.
-
27% of the doctors* prescriptions were for 3 to 4 drugs
Only 4.3% of prescriptions were for more than 4 drugs.
—
the maximum number of pres riptions were for Nutritional
Products (tonics, enzymatic preparations and vitamins), then
antiinfectives (antibiotics and sulfas) and then analgesics.
—
58% of the self medicated drugs were schedule 'L* and 'li*
drugs which can ot be sold without prescription, nor should be
consumed without medical supervision, because of the associated
major side effects and toxicity.
-
amongst self administered drugs analgesics, nutritional
products and antibiotics topped the list.
Analgesics, antipyretics and anti-inflammatory drugs:
-
30.2% of the self prescribed analgesics, antipyretics- anc
anti-inflammatory agents
were
scheduled drugs. These were
mainly analgin, phenylbutazone (with or without corticosteroid: )
and ibuprofen.
—
an earlier survey by the CERF (Consumer Education and Research
Centre, Ahmedabad) h.id shown that of 13 over-the-counter brands
of these drugs, 11 did not provide any information. The 44 doctors
interviewed reporte d s eing or: an average 8 to 10 cases of drug
,,,,,, 2
2
drug poisoning per month.
Vitamins and Tonics:
only 31% persons surveyed had a correct concept regarding
nutritional supplements. The majority held the erroneous view
that daily consumption of tonics was essential for health!
The credit for this false belief goes to advertising pr .ssure
as well as doctors’ prescription practices.
-
16% of the doctors had pr scribed simultaneously more than
one vitamin preparation having the same ingredientsin various
dosage forms.
—
iron deficiency anemia, B2 deficiency, were the commonest
deficiencies in the population but sales of B Complex
(Bl, B2, B6 B12) combinations and other vitamins topped
the list of sales figures.
Antibiotics:
-
over 30% of the doctors’ prescriptions contained antibiotics.
-
approximately 12.8% of self—prescribed drugs were antibiotics.
-
most antibiotic prescriptions were for sulfa and trimethoprim
combinations, tetracyclines and penicillin, in that order.
-
tetracycline, sulfa-trimethoprim and penicillin were the
most popular self-prescribed
-
drugs.
30% of the antibiotics purchased for self medication were for
less than a day. Only 18% were purchased for a full course of
five days. Only 40% of prescriptions for antibiotics were bought
for five days.

The findings of the NIN and CERC surveys indicate the urgent need for
public education where disease and drugs are concerned.

1.
To build awareness amongst general public with regard
to the usefulness/uselessness/benefit-risk ratio of
various systems of medicine in practice.
2.

2.
The structure/members of the Forum
A decentralised structure with an apex body located in
Bangalore was thought appropriate.
To initiate the district
based network of the forum it was suggested that voluntary
organisations based in different parts of Karnataka and
preferably with doctors involved in these programmes have to
be identified and these individual centres work independently
and in union with the apex body.
In order to promote this
idea end co-opt members into the apex body, it was proposed
that discussions have to be held individually and collectively
with the following members and to invite their suggestions
and reactions on the above aspects.
1. Dr C M Francis
2. Mr Premanand Shetty - Ex-Drug Controller, Karnataka
3. Mr Shanbaug - Ex-Drug Controller, Karnataka

Dissemination of information
Dissemination of information to the public was given
enough thought during the meeting. Having an independent
bulletin either in English or in Kannada or in both though
may be necessary in the long run, it was considered more
economical to use other bulletins or journals that are
already existing to disseminate information.
The use of
the T.V. through the Bangalore Doordarshan was contemplated
and it would be explored by Dr batish Kumar and Mr Hanaiah.
4.
Mobilisation of funds
To begin with, the forum will not depend on any assured
source of funds for the conducting of the LAF-K activities.
It was suggested by the members that the Forum approach
various agencies in India including Karnataka Rajya Vignana
Parishad as also appeal to individuals for donations, for
specific projects.

K Gopinathan (KG)
Ajith Lalwani (a medical
student from UK)
KG welcomed the members and briefed the new members the
idea of getting together of various individuals involved
in health and development work, in such a platform, where
the views and experiences of each of them could be shared
for the benefit of one another. He then requested the
members especially those who have started new experiments
to share their experiences.
GD
He had started his community health programme in a
place called KULAVALLI (cluster of 7 villages) in
Kittur, 30 kms away from Dharward. This is an area, where
the Government has entered into an agreement with Messrs
Karnataka Pulpwood Limited for eucalyptus plantation. In
his experience it was found that eucalyptus cultivation
was not at all an issue for the villagers. Their need was
for land, school, power supply and so.on. The villages
are not accessible by motor transport. People use cycle,
bullock cart etc. The village belonged to one Inamdar
(area being 1700 acres). The land was a gift to Inamdar
by British, for helping them catch one Sangoli Rayanna.
This land is occupied by poor people without obtaining
the legal rights. There is a nationalised bank, the services
of which are not utilized by the villagers; they consider
the bank employees "Englishmen". The villagers, however,
frequent a bank called "Boot Bank", who charges 250%
interest. The bank got this peculiar name because the
defaulters are dealt with their 'boots'.
The total population of these villages is 2777. Forest
dwelling is the main occupation. Two community health
guides attached to Kittur PHC visit these villages.
General Practitioners visit these villages, spending an
hour a day in each village. Muslims and Nayakas are the
communities.
2
2
GD's modus operand! is to stay overnight in these
villages and meei the people discussing with them to
find out their felt needs. One of their felt needs was
education and they wanted a school and they agreed to
contribute whatever they have (like bricks, wood, leaves
etc.) to build a shed. But the question was what sort of
education they should give. Anyway the school started
functioning on a non-formal basis, in the evenings.
It was decided that no health programme would be initiated
till the villagers asks for it.
JP; He explained about his involvement with a research
study on "Community Participation in Mental Health
Care" being undertaken by his department at NIMHANS. The
area covered is under Jugani with a 75000 population,
where' the people contribute to a Health Fund. Although
the study is titled as "Participation", there exists
only "quasi participation", due to ICMR wanting their
"conventional project protocol". JP started interviewing
the people to know what they are wanting in the health
field and to identify their priorities. The method of
getting these information was by recording the discussion
using a tape recorder (without the knowledge of the
interviewee.)
KVS/US; During the past few months they were visiting
various projects in Andhra Pradesh, Tamilnadu and Orissa
in connection with training/evaluation. They were recently
at the Association for Sarva Seva Farms, an off shoot
of Vinobhaji's Bhoodan at Madurai. KVS spent sometime
at Deena Sewa Sangha, looking through the files and
brought out a book called "Continuing Story of the Social
Workers Brotherhood". Uma had been involved in conducting
’Workshops on "Communication and Education" for various
projects including Anganwadi Workers under the ICDS
programme. Changes needed in the educational materials
and evolving new methods in communication are" looked into.
He now wishes to get back to health/medical field
after years of involving in non-medical work. Presently
he is in search of an institution where he could get an
attachment to work in this area. A Consumer Service Society
has been started at Hunsur where issues related to drug use/
abuse are also dealt with. On the request of some of. the
members, he shared his African experience to the group.
GP;
3
■3
HS;
He is involved in documenting tribal knowledge on
different species of trees in the surrounding areas
of BR Hills including their knowledge on astronomy. A
vocational training centre with a view to imparting
employment oriented trade/skills on social forestry,
sericulture etc., is planned.
She is involved with the School' Health programme
of Deena Sewa Sangh, Bangalore. Behavioural Sciences/
holistic health, children needing attention are .covered
in this programme with the help of Dr Malavyka Kapoor
of- NIMHANS. Has attended Workshops, meetings on various
issues in the recent past. She is now in the process of
collecting materials on development of human beings.
MZ;
SDM? She briefed the group about her .training programmes
in Health and Development. Two 10 weeks training
programmes per year are conducted—6 weeks class room
teaching and 4 weeks at the field. After the training
follow, up visits and Workshops/participatory evaluation
are conducted in the field. Topics includes health and
community development; drug action; indigenous medicine;
nutrition; legal aid; cooperation; leprosy; teaching
methodologies; cost analysis; accounts. Every 18 months
a Core Group Workshop is conducted. The participants in
this Workshop being the best trainees in the proceeding
training programmes. The course fee is subsidised.
VB;
He is involved with a Leprosy Project at Karigiri.
While interacting with the members, he gave an account
of how the government, can topple the initiatives of
volags as also how they can influence the same volags.
He told the group, an incident whib took place in Tamilnadu
involving an activist group (he did not want to divulge
the name of the group). The activists were working with
a group of women, building awareness. One one occasion
this group of women marched to'the Primary Health Centre
and gheravoed the staff for their inaction; they also went
to the DHO asking him to look into the issue in question.
The situation improved. Having gained confidence, when
there was draught in the area, they approached the
Sub Collector demanding arrangements for water supply.
4
4
The Sub Collector ordered for immediate remedial action.
The Government ac Madras were surprised to learn of the
effectiveness of the Women’s group and asked the
authorities to conduct an enquiry into the happenings
to find out -who was behind the group. Under "law and
order" problem, the activists records were confiscated
and the staff except, the Director (who was not in statici)
were taken to police custody. After the incident, the
staff arrested by the polic left the organization and the
Director continues his work in accordance with the wishes
of the government officials, with government assistance.
VB also mentioned about a funding agency who refused
to continue supporting a project on the ground that
"the work of the project was in line with the government
policies".
There was some discussion .on the following broader
issues arising out of points mentioned by those of the
participants who shared about their work;
1.
Government initiatives often overlook the interests
and needs of the people.
2.
The general masses have recognised the importance
of education/literacy.
3.
The conventional approach to various studies being
followed by the government establishments does not .
allow the researchers the necessary freedom to
evolve their own methodology. Actual participation
of the community in the governmental programmes and
or its research activities, therefore, remains only
in paper.
4.
■ New methods are to be evolved in communicating
health messages to the people. Changes are to be
made in the educational materials, presently
available, for their effectiveness.
5.
The voluntary organizations may sometime have to
succumb to political pressures in order to avoid
the authorities branding them as anti-government.
6.
Some funding agencies do not support NGOs collaborating/
supplementing government programmes.

Aspirin May Cause More Harm Than Good 7/2/00
file:///D|/rNFO FROM INTERNET/aspirin cffects-jul2.htm

Aspirm
Caojs® M@re tnWm TTIhain) ®@©^
Taking low dose aspirin as a preventive measure against
coronary heart disease, which is a very common practice,
may actually cause more harm than good, according to'a
just published study.
Bow.-,Sugar./VfacU.ae
Caiciam Channel
Blockers, Ca,us,e.G?
British researchers identified over 5,000 UK men, aged
between 45 and 69 years, who were at increased risk of
coronary heart disease but had not previously had heart
trouble. The men were randomly divided into four different
treatment groups to accurately establish the effect of
aspirin.
The authors found a greater beneficial effect of aspirin in
men with low rather than high blood pressures, not only for
coronary heart disease but also for stroke, although the
modest benefit does not necessarily outweigh the risk of
bleeding. Men with higher pressures may derive no
protective benefit from aspirin but will risk possible serious
bleeding.
Given the widespread use of aspirin for the prevention of
coronary heart disease, the study's authors suggest that
these findings have important implications, although they
admit that further trials are needed to confirm the results.
Because of the strong correlation between blood pressure
found in this study, the authors also stress the importance
of adequately controlling blood pressure for those in whom
the preventive use of aspirin is being considered. In
addition, men who have previously had heart trouble and
strokes and are taking aspirin should continue to do so,
unless instructed otherwise, since they are more likely to
obtain a greater benefit than the general population.

The following model list of essential drugs
is taken from the WHO Technical Report series
770 (WHO, Geneva, 1988 "The use of Essential
Drugs").
MODEL LIST OF ESSENTIAL DRUGS
EXPLANATORY NOTES"'
Since the first report on the selection of essential drugs was
published in 1977, the concept of essential drugs has become widely
applied. It has provided a rational basis not only for drug procu
rement at national level but also for establishing drug require
ments at various levels within the health care system.
The international nonproprietary (generic) names for drugs or phar
maceutical substances should be used whenever available,and presc
ribers should be provided with a cross-index of nonproprietary and
proprietary names.
The concept of essential drugs has been endorsed unanimously by
the World Health Assembly. It is intended to be flexible and
adaptable to many different situations; exactly what is regarded
as essential remains a national responsibility.
The wide applicability of the concept is now evident from exper
ience gained in many countries. Most national lists of essential
drugs are stratified to reflect requirements at different levels
within the health care infrastructure. Typically, a very short
list has been compiled for community health workers while the most
comprehensive lists have been reserved for large urban and regional
hospitals.
One hundred and nine countries have now developed lists of essen
tial drugs and more than 40 countries are making great efforts to
implement programmes based on the essential-drugs concept. The
priorities and approaches differ.from country to country in accor
dance with each country's socioeconomic situation, but the concep
tual basis is the same. The WHO Action Programme on Essential
Drugs provides a platform for a harmonized and collective search .
for suitable and feasible- solutions to the problem of the unavaila
bility of the most essential drugs to the majority of the world's
population.
Many drugs included in the list are preceded by a square symbol(_#)J
to indicate that they represent an example of a therapeutic group
and that various drugs could serve as alternatives. It is imper
ative that this be understood when drugs are selected at national
level, since choice is then influenced by the comparative cost and
availability of equivalent products. Examples of acceptable substi
tutions include :
(#) Codeine : Other drugs for the symptomatic treatment of diarrhoea
such as diphenoxylate or loperamide or, when indicated for cough
relief, noscapinc- or dextromethorphan.
(#) Hydrochlorothiazide : Any other thiazide-type diuretic currently
in broad clinical useT
(#) Hydralazine : Any other peripheral vasodilator having an anti
hypertensive effect.
(#) Senna : Any mild stimulant laxative (Either synthetic or of
plant origin)
(#) Sulfadimidine : Any other short-acting, systematically active
sulfonamide unlikely to cause crystalluria.
Hazardous, Bannable and Dumped Drugs
The issue of dumped drugs has been in the news for the past
few years. The drug companies involved in the manufacture
and sales of such drugs have received their due share of condem
nation. Foreign governments
policies, which provided scope
for exports of such hazardous products have been also condemned,
g.,
e.
the Clayton Amendment Act and the U.S. Regulation.
It is well known that sales of medical technologies and drugs
is a commerical enterprise, the motivation being profit rather
than "service1’ or "welfare work".
Realising all this, the question arises as to how much can we,
as citizens of India, expect our drug control authorities to
safeguard our interests. The pressure from the drug industry
is immense. In spite of knowing this, our expectations from
the drug control authorities is high. After all our pharmaceutical
industry is the most developed in the Third World. According
to UNIDO, it belongs to Category V — developed enough to
be self-sufficient.
We have demanded that our imports, production and sales should
give priority to essential, life-saving drugs over irrational and
hazardous drugs, as per WHO's guidelines for Essential Drugs.
The drug industry and its supporters allege that the concept
of essential drugs is only for struggling, less developed countries
of the Third World and not for a country like India, with its
well-developed industry and its high and advanced level of
medical expertise. However, this same lobby puts India in the
category of less developed countries when it comes to the
issue of banning drugs and drug control. The lobby claims that
consideration of hazards over efficacy is a luxury which we
cannot afford.
However, consumers anywhere in the world have the right to
expect that irrational and hazardous drugs are not issued licences
and that licences of banned drugs should be withdrawn .as soon
as possible, the ban implemented, and that all drugs in the
market are quality - controlled. We have 20 per cent substandard
drugs . One out of every five drugs will not be effective.
With the incereasing number of spurious
drugs floating in
the market, the problem is beginning to take on dangerous
proportions.
: 2 :
Since 1980 we've been concerned about
and hazardous drugs.
SOME
BANNABLE
DRUGS
—
WHAT
this
IS THE
issue of dumped
POSITION
NOW
Under Section 23 P of the Drugs and Cosmetic Act
of 1940, the Central government has the power to
issue such directions to the State Governments as
required to execute the Drug Act. under Section
18 of the Act the State Government has the power
to prohibit manufacture,
distribution and sale of
drugs by a gazette notification.
The sub-committee of the Drugs Consultative Committee,
in its 1980 report, recommended the banning of 23 combinations
of drugs, giving their reasons for such banning, 16 categories
of these drugs were recommended for immediate
weeding
and seven of the categories were to be weeded out over a
specified time. Over 500 brand drugs would be thus affected.
This report was presented to the Durg Consultative Committee
at a special meeting on 10.10.81, and later to the Drug Technical
Advisory Board (DTAB) and the Ministry of Health and Family
Welfare accepted it in 1981.
The DTAB, a Statuatory Body under Section 5 of the Drugs
and Cosmetics Act of 1940 recommended banning of 18 fixed
dose combinations. These drugs were randomly selected from
the Pharmaceutical Guide. Out of the 350 brand names affected,
44 were marketed by the foreiqn sector, 8 by public sector,
and 298 by private sector. Most of these drugs were being
produced by national companies According to the authorities,
"the purpose was to give time limit to firms who may already
have purchased the bulk drugs form manufacturing the formula
ties''. What compassion and consideration for the drug companies!
SOME BATTLES
Halogenated Hydroxyquinoline
Ban of fixed dose combinations of halogenated hydroxyquinoline
: 3 :
was to be effective from 1.11.82. The date of the ban was
extended to 31.3.83 through DO No. X19013/8/81-D dated 13.8.82.
High Doses of EP Drugs
Through another DO. No. 12-48/79 DC dated 26.6.82, the Drug
Controller of India directed the State Drug Controllers to ban
the manufacture of high- dose Estrogen-Progesterone combinations
from 31.3.83 and their sales from 30.6.83.
M/s. Unichem Labs, Bombay (OP 2927/82 of writ petion 2928/82), M/s. Nicholas Labs, Bombay and M/s. Organon (now known
as Infac (India) Ltd., Calcutta filed writ petitions in Bombay
and Calcutta high courts challenging the ban. Their contention
was that the Central Government has no powers to ban the
drugs. The High Court of Bombay and the High Court of Calcutta
have granted stay orders against the ban. Now these products
are available in the market.
Section 10A and 26A of the amended Drugs and Cosmetics
Act (April 1982) empower the Central Government to prohibit
import, manufacture and sale of any drugs considered harmful/
toxic or irrational, etc. Since the matter was in court during
the gazette notification of 23.7.83, this combination of drugs
has not been included in it.
What is absolutely objectionable is the fact that — inspite
of the act of the Drug Controller of India's ban of the production
and sale of EP drugs, M/s. Organon have managed to obtain
extension of licences to manufacture these products for another
two years.
Paediatric Tetracycline
Although this drug is banned in its oral liquid from to discontinue
its being prescribed for children because of its often serious
side-effects, it is being manufactured today as a tablet of
30mg. for children — an example of how a 'company can follow
the letter of law and yet disobey it without any legal
consequences.
: 4 ;
Aspirin and Vitamin C
In October 1982, M/s. Nicholas Labs, Bombay filed a writ petition
in the Bombay High Court against the decision to ban the fixed
dose combinations of Aspirin with Vitamin C. The Court ruled
that the State Drug Controller has no power under Section
18 of the Drugs and Cosmetics Act to stop the manufacture
and sales of this product. However, it would be open to the
respondents as and when the law has been enacted, to pass
any fesh ordef as it is considered necessary in accordance with
the law after following procedures prescribed by the Government.
Subsequent to the Drug Amendment Act of 1.2.83, the manufac
turers have again gone to court challenging the
Central
government and Sections 26 A and 10A on the grounds of "lack
of objective criterion for such ban".
This has resulted in the FDA — Maharashtra (which is supposed
to be having the best drug control mechanism in India) informing
the Drug Controller of India that, in the light of the rul ing given
by the Bombay High Court, "it would not be possible for him
to take any action to stop the manufacture and sale of any
of the fixed dose combinations in question". (Letter dated 9.6.1984
ov the Drug Controller of India to the Voluntary Health Associa
tion of India).
Gazette Ambiguities
It is not clear trom the DO letter banning 22 drugs, whether
some drugs like strychnine and yohimbine, and caffesine are
banned only in some combinations, or in all combinations :
any drug containing yohimbine, or strychinine would be
banned (as neither of the two were considered to have
any therapeutic value and infact could lead to serious
side effects).
or the ban was applicable to drugs containing both yohimbine
and strychnine.
or to yomhimbine
vitamins
and
strychnine
with
testesterone
or
: 5 :
or ONLY to drugs which contained all four : yohimbine,
strychine, testesterone and vitamins.
Bangladesh banned 1742 drugs in June 1982. The time period
given to the drug companies to withdraw these products from
the market, to destroy these products was three to nine months,
depending on the product. They were strictly prohibited from
exporting these products to other countries. But we failed to
ban even a few hundreds, let alone 1742 drugs. The time period
given to drug companies was to complete the manufacture
of their formulation and sell off their stocks.
WHO IS MORE IMPORANT
THE CONSUMER ??
—
THE
DRUG
COMPANY
OR
The drug policy is now on the anvil. It is now that we can
assume the responsibility for putting people's health before
the health of the industry. If Indian people have to become
healthy, Indian Drug Policy needs to be rational. The choice
is ours — and we must make a decision now.

OBSTETRIC DRUG INFORMATION CELL AT RVHA TO ALERT AGAINST
HARMFUL DRUGS IN PREGNANCY •
A recent survey by the RVHA of the maternity centers in the
city of Jaipur revealed a very high incidence of still births,
congenital anomalies and of abnormal pregnancies needing assisted
deliveries by caesarean section.One of the possible contributory
factor for the incidence of stil births, congenital defects etc
is the indiscriminate and indiscreet use of the drugs in pregnan
cy.
Prescription and intake of drugs in pregnancy needs much
higher level of awareness and readily available information about
the possible harmful affects of the drugs in pregnancy. In India,
where therapeutic preparations marketed run in thousands, it is
still more difficult to be aware of the possible harmful content
of a specific preparation. Good intentions of physicians to do no,
harm to conceptus, while prescribing to a pregnant woman for her
disease and complaints, are thwarted by the lack of readily
available information about the effect on pregnancy of the other
wise commonly prescribed safe drugs to patients. A pregnant lady
has no way to check if the prescribed medicines for her ailment
are likely to harm her precious child in the womb.
To counter the above mentioned adversities, countries with
better developed and more responsive health care systems, run
obstetric drug information centers that disseminate the required
information to enable rational and non-harmful prescription of
drugs in pregnancy. Rajasthan Voluntary Health Association is
perhaps the first in the country to attempt to establish such an
obstetric drug information cell.
rh t h u
The Obstetric Drug Information Cell at the RVHA has alreadyprepared a computer based data-base of the drugs by their generic
and brand names, in term of their reported and recognised (by
drug control authorities of India) effects on pregnancy. Lists of
the drugs that are either not at all to be given in pregnancy
(contraindicated drugs) and those that have to be prescribed with
special caution ( special precaution) are available both by thei
generic and brand names. Lists are also available for the use o
practitioners of various specialities according to the class o
drugs pertaining to their specialities.
The Obstetric Drug Information Cell will provide information
to any pregnant lady seeking information about the possibility of
any harmful effect, on the child in the womb or the pregnancy, of
a drug prescribed to her. The patient may contact, with the
prescription, personally or by sending a photocopy of the pre
scription by post, the Obstetric Drug Information Cell, Rajasthan
Voluntary Health Association, C-41, Dev Nagar, Tonk Road, Jaipur302018, ( between 11 AM to 1 PM for personal visit). During this
time information will also be available on telephone No.512021.
The Obstetric Drug Information Cell will also mail lists of
the contraindicated and the special precaution lists of drugs in
pregnancy to various doctors and hospitals, and to any one seek
ing such lists, subject to the availability of the funds. ,
OBSTETRIC DRUG INFORMATION CELL
Rajasthan Voluntary Health Association, Jaipur
A large number of drugs, approved as safe in non-pregnant and in
non-lactating women, are known to be unsafe in pregnancy and
lactation. These drugs are either contraindicated or are to be
avoided as far as possible (to be given with caution) because of
their known, or potential harmful effect to a pregnant or a
lactating mother, or to the child in the womb, or to a child on
breast feed.
The drugs that may harm the child or the mother or- adversely
effect the pregnancy outcome, besides being1. drugs taken for pregnancy related conditions
might have been taken for
2. treatment of infertility
or
3. for an acute or chronic condition from which a pregnant
or a lactating woman might suffer.
Potential of harm to foetus is maximum in the first three month^
of pregnancy. The development of the organs in a foetus takd®
place in the first three months of pregnancy. The foetus, during
this period, particularly from 18th or 60th day of conception, is
most vulnerable to the harmful effect of the drugs, which may
cause congenital defects leading either to death of the child in
the womb and abortion, or birth of a child with defects.
Substantial risk in second trimester. During the next three
months, drugs may still cause disorders of growth and function,
especially of the brain and the spinal cord, that are mostly
non-fatal.
In the last
three months of pregnancy, drugs may cause problems in the child
birth, or immediately following it, frequently drug related fatal
respiratory failure in the new born, more so if the child is born
premature.Some drugs may cause excessive bleeding in the mother.
Risk to the child and the mother in late pregnancy.
A variety of adverse pregnancy out-comes, such as, abortion^
still birth, neonatal death, congenital defects, or defects in
functioning of the brain etc, are caused by drugs taken in preg
nancy. Rates of such cut-comes are
much higher in Rajasthan as
compared to other parts of our country, and in the country as a
whole than in the developed nations. Excessive and indiscriminate
prescription and consumption of drugs in pregnancy is one cause
of it..
A child on breast feed is vulnerable to the adverse effect of all
the drugs taken by the mother that are secreted in the breast
milk. ’

To prevent this large scale medical violence against pregnant
women and their innocent children in the womb, an Obstetric Drug
Information Cell has been created at the Rajasthan Voluntary

2.
The Cell will circulate amongst doctors a list of drugs
that
are either contraindicated or are to be pre

of similar status of
drugs in lactation . This is to
enhance 'the awareness of doctors about the safety
standards of these drugs in pregnancy and lactation and

THE AUSTRALIAN RISK
CATEGORIZATION SYSTEM FOR
DRUGS USED IN PREGNANCY
The Australian categorization consists of five separate categories:
.CATEGORY A
Drugs which have been taken by a large number of pregnant.
women and women of childbearing age without any proven increase
in the frequency of malformations or other direct or
indirect harmful effects on the fetus having been observed.
CATEGORY B
Drugs which have been taken by only a limited number of
pregnant women and women of childbearing age, without an
increase in the frequency of malformation or other direct or
indirect harmful effects on the human fetus having been observed.
As experience of effects of drugs in this category in humans is
limited, results of toxicological studies to date (including repro
duction studies in animals) arc indicated by allocation to one of
three subgroups:
x
GROUP Bl •
Studies in animals * have not shown evidence of an increased
occurrence of fetal damage.
GROUP B2 -.-
Studies in animals‘arc inadequate or may be lacking, but available
data show no evidence of an increased occurrence of fetal damage.
^GroupbT’^:'
Studies in animals ‘ have shown evidence of an increased
occurrence of fetal damage, the significance of which is
considered uncertain in humans.
--^CATEGORY C
Drugs which, owing to their pharmacological effects, have
caused or may be suspected of causing, harmful effects on the
human fetus or neonate without causing malformations.These
effects may be reversible. Accompanying texts should be
consulted for further details.
' /.'- CATEGORY D
Drugs which have caused, arc suspected to have caused, or may be
expected to cause, an increased incidence of human fetal
malformations or irreversible damage. These drugs may also have
adverse pharmacological effects. Accompanying texts should
be consulted for further details.
CATEGORY X; Drugs that have such a high risk of causing permanent damage to
the fetus that they should not be used in pregnancy or when there
is a possibility of pregnane}'.
■ '
" Animal studies submitted in support of new drug applications
must conform to New Drug Form Guidelines.

Pregnancy” categorization booklet. These notes are based on that booklet with additional comments

■
NOTES ON SAFETY OF VARIOUS
t DRUGS AND DRUG GROUPS
’
1
Angiotensin - Converting enzyme (ACE) inhibitors:
Captopril and enalapril are rated as D due to reports of fetal deaths in-utero.
Whilst there is no evidence to suggest that these drugs are teratogenic in humans, it
has been suggested that late in pregnancy, these drugs have effects on the fetal '
renin-angiotensin system, which may be potentially harmful. Therefore, they air best
avoided during prcgnancy.'l4A',1For similar reasons the newer drugs Fosinopril and
Lisinopril are also rated D in pregnancy.
2
Acyclovir
During pregnancy there is no evidence that acyclovir prevents transmission of genital
herpes simplex from mother to fetus and administration during pregnancy is usually
contraindicated on theoretical grounds. p> However, its use should be considered in a
primary attack because viraemia occurs and potential damage could result in the
infant’6’
'
3
Aminoglycosides
Gentamicin, kanamycin, neomycin, tobramycin, amikacin, netilmicin.
Gentamicin and other aminoglycosides are known to cross the placenta. There is
evidence of selective uptake of gentamicin by the fetal kidney resulting in cellular
■ damage (probably reversible) to immature nephrons. Eighth cranial nerve damage has
also been reported following in-utero exposure to some of the aminoglycosides.
Because of their chemical similarity, all aminoglycosides must be considered
» potentially nephrotoxic and ototoxic to the fetus. It should also be noted that
' therapeutic blood levels in the mother do not equate with safety for the fetus.
4
Amiodarone
Because of the long half-life of amiodarone and its major metabolite, and the potential
to cause abnormal thyroid function and bradycardia in the fetus, its use is probab.y
best avoided in the. three months before and throughout the duration of pregnancy.
Where exposure of the fetus is unavoidable, thyroid function (including TSH) should
be assessed promptly in the newborn infant.
.
5
Anticonvulsants •
The riskof a mother with epilepsy giving birth to a baby with an abnormality is about
three times that of die normal population. Some of this risk is due to the
anticonvulsant drugs taken. Mothers, taking more than bne anticonvulsant drug,
might have a higher risk of having a baby with a .malformation than mothers taking ,
one drug. Phenytoin sodium, taken during pregnancy, has been associated with
distinctive craniofacial abnormalities, mental and growth deficiency and less
frequently, oral clefts and cardiac anomalies. This clinical pattern is sometimes called'
die ‘fetal hydantoin syndrome’.
Sodium valproate (valproic acid), it taken in the first trimester of pregnancy, is
suspected of causing an increased risk of neural tube defects (especially spina bifida) in
the exposed fetus; Women taking sodium valproate (valproic acid,, who become
pregnant, should bo encouraged to consider routine ultrasound and amniocentesis for
prenatal diagnosis of such abnormalities.(7) Alternatively, pre-pregnancy genetic
counselling is advised.
In practice, if a padent is stabilized on anticonvulsants prior to pregnancy, and the
padent is counselled as to the potential increase in overall risk, and wishes to continue
with the pregnancy, this therapy is usually continued for that patient throughout the
pregnancy, with close serum monitoring where this is possible. I: has also been
suggested that folate supplementation may reduce, the potential fur teratogenic
outcome. This is in line with the general consensus of advice for these patients
during pregnancy, f7-s’. We would strongly disagree with the D rating for clonazepam,
and would place it at a B3 rating since there is no epidemiological evidence of
teratogenicity with die use of benzodiazepines other than studies cf small numbers
with'inconsistent results. For other fetal effects of benzodiazepines, please refer to
benzodiazepine notes (N...iz;.
6
Antihistamines and Anti-emetics.
The Australian categorisation differentiates between some antihistamines and others;
on their chemical basis, namely that some are phenothiazine derivatives, and that
phenodiiazines used late in pregnane)', have caused prolonged extra-pyramidal
disturbances in the child.
•
-
Phenothiazincs are given a C categorisation, whilst meclozine, dcxc.hlorpheniramine.
and the antiemetic mctoclopmnmle are given an A categorisation. The antihistamine:.
azaadine, methdilazinc and terfcnzJine are given a B2 rating.
3
•3
Doxylaminc is no longer available as a single ingredient, but is contained in a
combination product with paracetamol and codeine. This combination productMersyndol (Merrell Dow) may be regarded as safe for short-term use during
pregnancy. Astemizole is given a C rating because of its long (4-month) elimination
half-life. Because of the potential to accumulate, it should probably be avoided during
pregnancy. In practice, we would not differentiate between the older antihistamines
and anti-emetic preparations, but agree that there may be the theoretical possibility of
extra pyramidal effects from phenothiazines, when used late in pregnancy. There are
insufficient data on loratadine and terfenadine use in pregnancy. Therefore they are
not recommended for use at this stage.

Antimalarial Preparations
>3
O
The antimalarial preparation pyrimethamine is given a B3 categorisation.
Chloroquine and related substances arc given a D categorisation. The antimalarial
combination of pyrimethamine and dapsone is given a B3 rating whilst ,
pyrimethamine and sulfadoxine is given a C rating.
0
O
£
The ADEC categorisation booklet notes that the use of chloroquine and related drug?
in the prophylaxis of malaria is accepted because the small risk to the fetus with the
low doses is outweighed by the benefits to the mother and the fetus.
The difference between pyrimethamine-dapsone and pyrimethamine-sulfadoxine is
that sulfadoxine, and other long acting sulphonamides, may cause kemicterus in
babies during the first month of life, by displacing bilirubin from plasma albumin.
; 3
O
O
Q
3
The difference in the ratings reflects, fairly well, the advice that we give, with regard
to these preparations, namely that chloroquine is regarded as being safe if it is used for
prevention of malaria, and that the pyrimethamine-dapsone combination is not
established as being as safe as chloroquine but may need to be given if exposure to
chloroquine-resistant strains of malaria cannot be avoided. Where this is the case,
folate supplementation maybe used, to reduce the theoretical potential for teratogenic
outcome l’’. Mefloquine has been used later in pregnancy. Not recommended for use
in the first trimester, as limited teratogenicity data are available.
Pyrimethamine-sulfadoxine is generally pct recommended during pregnancy.
8
0
~3
0
Antithyroid Drugs
Antithyroid agents may.cause congenital goitre by inhibiting thyroxine synthesis in
the fetus. During pregnancy these products should therefore only be used after
carefully weighing the mother’s needs against the risk to the fetus. Propylthiouracil is
usually preferred to carbimazole because o: suggestions of potential congenital skin
lesions, arising from the use of carbimazole and related drugs during pregnancy'"'
Appetite Suppressants
9
Fenfluramine is rated B2 and others in the group are rated B3. There are no good
epidemiological data on safety of these preparations during pregnancy. They are not
usually recommended for use during pregnancy.
10
Analgesics (including Narcotics)
The opioid analgesics are given a C categorisation on the basis that narcotic analgesics
may cause respiratory depression in the newborn infant. It is stated that during the
last two to three hours before expected delivery, these preparations should only be
used after weighing die ijeeds of the mother against the risk to the fetus. This reflects
die reality of the risk-benefit ratio of these preparations, since morphine, pethidine
and other narcotics have been used in obstetric practice for many years, with the full
realisation that there may be the potential for respiratory depression. Codeine is given
a category A rating. The narcotic antagonist naloxone is rated A Paracetamol is
regarded as safe to use during pregnancy and is rated A
11
Barbiturates
Amylobarbitone, pentobarbitone, methylphenobarbitone
Barbiturates cross die placenta and appear in the fetus. After prolonged continuous
usage during a large part of pregnancy, they give rise to hypotension, reduced
respiratory function and hypothermia in the newborn child. Continuous treatment
during pregnancy and administration during labour should therefore be avoided.
12
Benzodiazepines
These drugs cross the placenta and appear in the fetus and may, after continuous
administration during a large part of pregnancy, give rise to hypotension, reduced
respiratory function and hypothermia in the newborn infant. Withdrawal symptoms
have been reported with this class of drugs. Continuous treatment during pregnancy
and administration of high doses in connection with delivery should therefore be
avoided. Short-term use, such as single night-time hypnotic dosage, is not considered
to be a problem.
13
Beta-adrenergic Blocking Agents
Beta-adrenergjt blocking agents arc rated as C, because of their potential to cause
bradycardia in the fetus and the newborn. Labetalol, metoprolol, and oxprenolol '■
■ have been successfully used, and have not demonstrated adverse effects in this
regard tiM'.u'M<> However, there have been some studies which have shown lower
birthweight in the infants ofatenolol-treated women compared with.altemative
treatments including labetalol. On that basis, the combined alpha and beta blocker,
labctalol may be a preferred option, to using beta blocking agents.
14'
Calcium-channel Blockers
Verapamil and nifedipine are rated C, due to their potential for fetal hypoxia. The
Swedish category for.verapamilis A. There is sufficient evidence to suggest that vera
pamil may be safely used in pregnancy and it would be more worthy of a Bl rating(,S).
15
Corticosteroids
In animal experiments, corticosteroids have been found to cause malformations of
various kinds (cleft palate, skeletal malformations). These findings do not seem to be
relevant to humans. Reduced placental and birth weight have been recorded in ’
animals and humans after long-term treatment.
Systemic corticosteroids, with the exception of replacement doses, arc listed as C
category, since there is obviously the possibility of adrenal cortex suppressions in the
newborn after'long-tcrm treatment.
Corticosteroids by inhalation have been widely used for many years without adverse
effects in pregnancy, up to 1600mcg daily
The short-term use of antepartum corticosteroids for the prevention of respiratory'
distress syndrome, when warranted, does not seem to pose a risk.
It is also documented that internal pulmonary oedema has been reported with
tocolysis and fluid overload.
Topical steroids, including fluorinated steroids, are listed as Category A. They are safe
for short-term use on unbroken skin for the treatment of appropriate dermatological
conditions.
16
Cyproterone
Cyproterone carries the potential for feminization of the male fetus, and therefore
should be avoided during pregnancy.
17
Thiazides and other diuretics
Thiazides, related diuretics and loop diuretics enter the fetal circulation and may cause
electrolyte disturbances. Neonatal thrombocytopenia has been reported with
thiazides and related diuretics. Loop diuretics, like trusemide and bumetamde are
probably also associated with this risk. During the latter part of pregnancy, products
of this type should therefore only be given on sound indications, and then in the
lowest effective dose.
18
. Haloperidol
Although there have been isolated case reports of birth defects following fetal
exposure to haloperidol in combination with other drugs, no definite cause and effect
relationship can be confirmed.
19
Anticoagulants
Coumarin derivatives, including warfarin, are rated D. We agree with this rating, due
to their teratogenic potential as well as the potential for haemorrhage.
Heparin is also given a C rating due to “increased incidence, of human loss and
prematurity associated with haemorrhage”. The Swedish category for heparin is B2.
We disagree with the C rating, as we believe that heparin, effectively monitored, has
been safely used for prophylaxis and treatment during pregnancy over several years
world-wade. We would place its rating at Bl. This is in line vrith clinical experience
and reviews on the subject(IM7). Obviously, with high-dose use of heparin during
pregnancy; considerations such as bone demineralization and other well known
potential adverse effects on the mother, need to be considered.
20
Lithium
X
Lithium enters the fetal circulation and cases of disturbances of thyroid function of
the newborn infant have been reported. Available data also indicatc'that lithium
dining pregnancy may cause malformations of the cardiovascular system.
21
Non-steroidal Anti-inflammatory Drugs
All drugs in this category arc given a C rating, on the basis of their inhibitory effect on
prostaglandin synthesis and, when given during the latter part of pregnancy, may cause
closure of the fetal ductus arteriosus. When given at term, they may prolong labour
and delay parturition
Continuous treatment with non-steroidal anti-inflammatory drugs during the last
month of pregnancy should only be given on sound indications.
Generally sptxiking, indomethacin, ibuprofen, diclofenac and similar preparations are
not withheld during pregnancy. Aside from the precautions noted above,- they do not
present other risks to the infant .
Aspirin is given a C rating, due to its potential for inhibition of prostaglandin
synthesis, which may cause premature closure ot the fetal ductus arteriosus, its
potential of prolonging labour, and its tendency to increase bleeding capacity in the
newborn
Aspirin-containing products should, therefore, be avoided in late
pregnancy.
Low-dose aspirin has been advocated for prevention of pre-eclampsia. However, if
used, it should be discontinued 1-2 weeks prior to expected date of delivery, because
of uncertainty as to the safety of low-dose aspirin and epidural anaesthesia.
The ADEC Classification booklet also notes that animal studies have shown~aspirin to
cause birth defects in animals, but there is ho conclusive evidence that aspirin causes
malformations in humans. This is in accordance with our own recommendations. It
is to be noted that paracetamol is listed as a category A preparation, as it has not
demonstrated any direct toxicity or teratogenicity when used during pregnancy.
22
Nitrofurantoin
Nitrofurantoin was originally given a C rating, in the.1989 classification, on the basis
of the caution required when given at term or to infants under one month, because of
the theoretical possibility of producing haemolytic anaemia due to immature enzyme
systems in the early neonatal period. In fact, this has not been reported to have
occurred in practice l’6’. It is placed in the A category in the 1992 classification.
Nitrofurantoin has been quite, widely and safely used throughout pregnancy for over
thirty years. In both the United States of America and Sweden it is placed in the
category equivalent to category A. An assessment of the literature confirms the view
that the rate of haematological reactions is very law (around 0.0004% of doses given).
We would, therefore, agree with the “A" categorization p72xl.
23
Sex Hormones, including Oral Contraceptives
Animal studies have shown that high doses of progestogens can cause masculinization
of the female fetus. Because of this virilising effect on the fetus, they are rated D.
The results from these experiments in animals co not seem to be relevant to humans.
in the low doses used in contraceptives.
Obviously, the rating with respect to.these hormones is of most relevance
retrospectively, in the case of inadvertent use of a particular drug in early pregnancy, as
these preparations would not normally be prescribed during pregnancy, if it were
known that the patient was pregnant. In this context, low dose progestogens should
probably be a Bl or B2 rating. (See also comments following, with regard to oral
contraceptives.)
We would also advocate individual counselling where appropriate, to the effect that
the inadvertent use ofdMylestranol, dydrogesterane or medroxyprogesterone in early
pregnancy, should not be regarded as a reason fcr interruption of pregnancy, as the
evidence suggests that the actual risk of virilization is minimal. Anabolic steroids are
rated D due to their potential for virilising effects on the fetus. Danazol has also
demonstrated an androgenic effect on the fetus tn several reported cases.
Stilboestrol is rated X.
Oral contraceptives (again, obviously inadvertently used in early pregnancy) are rated
B3. This is a reasonable rating, since there is no evidence that intake of oral
contraceptives during pregnancy represents an increased risk to the fetus. It should be
noted that the studies, indicating links between oral contraceptives and limb reduction
deformities, were all carried out during the years .when oral contraceptives contained
high-strength oestrogens and progestogens, prior to the introduction of the more
modem low-strength preparations, and progestogen-only preparations in the early
1980’s;
Indeed, early formulations, contained in some cases, 10 to 20 times the
equivalent steroid content compared to modem formulations.

Oral Hypoglycaemic Agents
In animal studies birth defects have been demonstrated. They should therefore net be
used during pregnancy but should be replaced by insulin.

Phenothiazines
Fluphenazine, perphenazine, chlorpromazine, pericyazine, thioridazine,
trifluoperazine, promazine, prochlorperazine.

prolonged extrapyramidal disturbances in the child.

Rifampicin
Bleeding, attributable to hypoprothrombinaemia, has been reported in newborn
infants and in mothers after the use of rifampicin during late pregnancy. In animal
experiments, rifampicin, given during organ development, has caused skeletal
malformations. If rifampicin is used during the last few weeks of pregnancy, vitamin
K should be given to the mother and the newborn infant.
28
3
Vitamin A
Sulphonamides
Sulphonamides may cause kernicterus in babies during the first month of life by
displacing bilirubin from plasma albumin. Sulphonamides should therefore be
avoided as far as possible during the last month of pregnancy.
The rapidly-excreted sulphonamide, sulphamethizole, may be regarded as being sue
for use in pregnancy, bearing in mind the concern about the use of sulphonamide; as
group late in pregnancy.
29
Tetracyclines
During the period of mineralisation of a child’s teeth (the second and third trimester
of pregnancy, the neonatal period and the first 8 years of life) tetracyclines may induce
hypoplasia of the enamel and discolouration of the teeth. Tetracyclines also
accumulate in the growing skeleton. These products should be avoided during the
second and third trimesters of pregnancy.
30
Tricyclic antidepressants
Amitriptyline, desipraminc, imipramine, trimipramine, nortriptyline, opipramol,
protriptyline, clomipramine.
Tricyclic antidepressants have not been shown to be associated with an increased
incidence of birth defects. However, there is evidence of interference with central
monoamine neurotransmission in rats. Care should be taken that there are sound
indications for the use of these antidepressants in pregnancy.
31
Vaccines
The ADEC categorisation booklet states:
“Women of child-bearing age should be tested prior to pregnancy. All seronegative
women of child-bearing age, provided they are not pregnant, should be offered
rubella vaccine. As the virus in rubella vaccine can cause fetal infection, it is desirable
that the vaccine should not be administered to any women who may be pregnant
Those administering the vaccine should be careful to instruct women to whom it is
given that they should not become pregnant for at least two full menstrual cycles.
However, to date, there have not been any rubella-like birth defects in the live bom
infants (about 400) of seronegative mothers vaccinated during or just before
pregnancy. Based on this experience, rubella vaccination during pregnancy need not
be the reason to recommend interruption of pregnancy. The final decision must be
made by the patient and her physician.”
We agree with these comments, and they are supported by the recommendations of
the United States Practices Advisory Committee of the Center for Disease Control,
U.S_A.(25). This group further states that “both yellow fever vaccine and oral polio
vaccine can be given to pregnant women at substantial risk of exposure to infection.
When vaccine is to be given during pregnancy, waiting until the second or third
trimester to minimiseAny concern over teratogenicity is a reasonable precaution” 651
Although adverse effects on the fetus have not been repotted, oral poliomyelitis
vaccine should not normally be given to women during the first four months of
pregnancy unless there are compelling reasons.
There is no convincing evidence of risk to the: fetus from immunisation of pregnant
women using inactivated virus vaccines, bacterial vaccines or toxoids t27).
32
Penicillamine
Penicillamine can cause cutis laxa in the human fetus
33
Bismuth Subnitrate
Bismuth is a heavy metal which crosses the placenta. Although there have beenno
reports of adverse effects in the human fetus, use of this preparation is not
recommended during pregnancy.
34
Sodium Nitroprusside
Sodium nitroprusside is used in high risk situations and there may be additional
hazards associated with the drug. It crosses the placenta. Short term use for control
of hypertensive crises may be safe provided die maternal pH and cyanide levels are
monitored.
35
Hydralazine
Hydralazine is used for treating hypertensive crises, where rapid blood pressure contol
is required. However, it is rated C, on the basis that fqtal distress and arrhythmia have
been reported following intravenous use late in pregnancy.
36
Metronidazole
Reviewingall the available animal and human data on the safety of metronidazole in
pregnancy, we may conclude that epidemiological and clinical data accumulated, over
a period of 30 years, has failed to show evidence of teratogenicity. With regard to
mutagenicity, experimentally, chemicals of a class to which metronidazole belongs,
may be shown to be mutagenic. I lowever, there is no evidence that metronidazole has
this effect in human usage.
r
~
Metronidazole is classified as B2 by the AD EC “Medicines In Pregnancy"
classification system.
I Therefore, if metronidazole is the drug of choice, for a particular infection during
i pregnancy, review of available evidence regarding its safety during pregnancy suggests
^that it may be safely used.

IMPACT OF POLICY CHANGES ON DRUG POLICY AND DRUG USE|
26, 27 August 1996
IRRATIONAL PARACETAMOL FDCs
Dr.W.V.Rane
Arogya Dakshata Mandal
The earliest paracetamol combination was with anti-histaminic and
ephedrine as systemic nasal decongestants. Lately the Drug
Controller of India has banned ephedrine anti-histaminic
combinations and drug manufacturers are changing over to
pseudoephedrine. British National Formulary (BNF, No.29, March
95, page 143) says "These preparations are of doubtful value but
unlike the preparations for local application they do not give
rise to rebound nasal congestion. They contain sympatheminetics,
and should therefore be avoided in patients with hypertension,
coronary heart disease, or diabetes, and in patients taking
monoamine-oxidase inhibitors
Many of the preparations also
contain antihistamines which may cause drowsiness and affect
ability to drive or operate machinery". I have mentioned here
under the FDCs and each FDC could have many brands. For sake of
convenience I have mentioned only one brand.
Paracetamol 500 mg + tripolidine 2.5 mg
+ Pseudophehedrine 60 mg.. Actified-Wellcome
Paracetamol 400 mg + Phenylephrine 5 mg
+ diphenpyraline 2.5 mg Cinaryl-Themis

+ Caffeine 50 mg Alex-Lyka
Paracetamol 500 mg + Promethazine 10 mg
Crophen-10 Shalaks
Paracetamol 500 mg + Codeine 10 mg + Caffeine 30 mg
+ Chlorpheniramine mal 2 mg Neofebrin-NeoPhar

BNF, Physicians' Desk Reference (PDR) and Martindale Extra
Pharmacopoea do not mention the combination of paracetamol and
Ibuprofen. But in India it is one of the most widely promoted
antipyretic and analgesic FDC. Some of the analgesic paracetamol
FDCs contain opioid drugs and BNF (NO.29 March 95 page 182) says
"Compound analgesic preparation containing paracetamol or aspirin
with a low dose of an opioid analgesic are commonly used, but the
advantages have not been substantiated. The low dose of the
opioid may be enough to cause opioid side-effects (in particular,
constipation) and can complicate the treatment of overdose, yet
may not provide significant additional relief of pain.... In
general, when assessing pain, it is necessary to weigh up
carefully whether there is a need for non-opioid and an opioid
analgesic to be taken simultaneously.... Caffeine is a weak
stimulant that is often included, in small doses, in analgesic
preparations. It does not contribute to’ the analgesic or anti
inflammatory effect of the preparation and may possibly aggravate
the gastric irritation caused by aspirin. Moreover, in excessive
dosage or on withdrawal caffeine may itself induce headache".
These are some of the Paracetamol FDCs of analgesics.

The E P Case
Mira Shiva
High dose combination of Oestrogen and
Progesterone has finally been banned. It is tragic
that the public had to fight for 6 long years for
getting a hazardous drug combination banned, that
too against all odds.
It was the socially conscious health activists
and consumers bodies that had initially raised the
issue in the first place, when the EP campaign was
launched way back in 1982 on Women’s Day on 8th
.March. Due credit goes to the press for keeping
"the issue alive all these years and supporting the
stand of the people.
It was the drug health and consumer groups
who protested when on 2! st July 1982, the ban order
for manufacture was given as December 1982 and
ban for sales as June 1983.
How could a drug
recognized as hazardous be allowed to be manufact
ured and then sold for almost another one year ?
It was not surprising when this was misused by the
manufacturers to challenge the hazardous nature
of the drug, saying that if the drug was hazardous
wouldn’t it have been banned immediately by the
DC authorities and since it wasn't - it was obvi
ously non hazardous 1
|The Legal Battle
The drug companies were quick enough to
| find the legal loopholes and the stay order against
the ban order was obtained from the Calcutta and
Bombay High Courts on
legal technicalities.
The fact that it involved a hazardous drug which
could maim and cripple the unborn foetus when
. consumed by ignorant pregnant women, -did not
appear
to be a matter worth considering.
Even making an attempt to find out the number of
women put at risk, with annual sales of Rs 7 crore
woitb of drugs (majority of them are consu
med for pregnancy tests and for induction of
abortion though on paper the indications permitted
had been only for secondary amenoorrhea) was
not done.
Questions were raised in the Parliament,
repeated requests were made to the Health Ministry
and Chemical Ministry to make attempts at getting
the stay vacated.
In the words of Supreme Court Justice
probably the government never wished to vacate the
stay; this became obvious because the subsequent
events are pointers to scheming.
Again it was due to a writ petition that
Supreme Court took up the issue again. Justice
Ranganath Mishra's comments on banning of
drugs is a telling commentry .
“This court as early as 11.4.1983
directed issue of notice to the Medical Council
of India, The Indian Medical Association,
The Drugs Medical Council of India, The In
dian Medical Association & The Drugs Control
Authorities of the States except that of Kerala,
as it was already made a respondent to the
writ petition. Obviously such notice was given
as in the opinion of the Court, the matter was
one of great importance and the Court looked
for participation of these authorities in the
debate with a view to assisting the Court in
the disposal of the matter. We are surprised
that the notice from the Court has not evoked
response excepting the State of Karnataka
Statutory bodies when called upon by a Court,
in particular the apex Court of the Country, are
duty-bound to respond and join the proceedings
before the Court. These bodies are not litig
ants and do not have the choice of keeping
away from the Court like private parties in
ordinary litigations opting to go ex-parte. The
present matter is certainly one which is suffici
ently important and the stake of the entire
nation is high; when the Court SUO moto
extended the ‘opportunity of being heard and
invited the named statutory or other authori
ties to come forward and place their view
7
points cn relevant aspects, an attitude of
callous indifference cannot be appreciated.
We hope and trust that there would be no
repetition of such a situation'.
The Public Hearings
It was unfortunate for public that the
public litigation case was referred back to the Drug
Controller of India. In its Court Order of Novem
ber 1986 Supreme Court gave direction to hold
public hearings to seek the views of consumers and
health groups and decision be taken by end of July
1987. The drug companies were shrewed enough to
use the professional bodies like FOGSI (Federation
of Obstetrics Gynaecology Society of India) to be
their spokesman FOGSI till the very end continued
to support the stand of the Drug manufacturers
stating that the drug was essential and absolutely
safe. Luminaries such as Dr. C. L. Jhaveri, Dr. C.
S. Dawn, Dr. B. N. Purandare did their utmost to
tilt the balance in favour of the manufacturers. The
role of the WHO expert and the Deputy Drug
Controller who chaired the Calcutta hearing was
not very creditable.
The silence of professional and academic
bodies such as IMA, IMC. at such a time was
unforgivable. It was only the Indian Academy of
Paediatrics that had expressed its deep concern
against the continued sales of high dose E. P. drugs.
The public hearing in Bombay ably proved that
when called upon, the women's organisations can
give a bitter fight for a cause. Even the public
notices for the public hearings were inserted inconspiciously In the papers, the hearings were stated
to be for “formulations of oestrogens and progest
erone”, in the first public notice and “combination
of oestrogen and progesterone” for the second one.
The failure to clearly state that the public hearings
were being held to decide whether or not to ban
combination of high dose Estrogen-Progesteronc, was
too significant to be overlooked as an unintended
errors. The way the 4 public hearings in Madras,
Delhi, Calcutta and Bombay were held on 5th Feb.
10th April, 10th July and 14th July 1987 respectively
is a story in itself. Even when the Drug Technical
Advisory Board met in May 1988, the minutes of
the 4 public hearings were not made available, nor
the summary of the arguments for and against the
drug ban was -sent to Boards members for prior in
formation. The fact that it took 6 long years to issue
a Gazette Notification to ban a drug — shows the
forces working on it. A drug, which is known to be
hazardous - which has been mainly used in pre
gnancy - a drug which was banned by the Drug
Controller of India himself in 1982 - a drug which
ICMR strongly recommended to be banned in 1982
as well as in 1987 - a drug which was not allowed
to be registered or sold in the parent country
Netberlands by Organon Infar. was strongly con
tested by drug manufacturers and they had the aud
acity to challenge the DCl's ban order in India.
Enforce the ban immeditely
The EP case involved a drug which the con
temporary Gynaecological medical literature does not
even mention, as it has no role-and as it is not us
ed by any gynaecologist or a doctor, as safer alter
natives exist. Not merely had several drug regulatory
authorities banned the drug, but several companies
had withdrawn the product themselves. It was du|
to sheer gist and perseverance of the drug activists,
health and consumer groups that the ban order has
come now. Should this be counted as success ?
We have learnt from past experience that
unenforced drug bans are as bad as no bans. The
Gazette Notification was issued on 15th July 1988.
Government media of AIR and Doordarshan should
have been used to inform the chemists, medical pro
fessionals and the ignorant consumers about the drug
clearly stating the brands and their manufacturers 1
The Drug Control Authorities owe this to the nation.
The stocks from the. manufacturers and the market
should be withdrawn and destroyed.
The Health Ministry has had 6 long years to
make available to the medical professionals the reco
mmended alternatives. Safe, low cost simple pregna-|
ncy tests, which basic health workers can use, should
be easily available as part of Mother and Child He
alth Programme. Permitting al this stage the manu
facturer and sales of high dose EP drugs as single
ingredients in the same dose would be ridiculing and
sabotaging the ban. The ban 1ms come 6 years too
late; now the implementation of the ban must be
immediate. The Drug Control Authorities and the
manufacturers must be held responsible if these
drugs continue to be sold. If this could happen for
a drug like high dose EP which the consumers and
health groups considered a watertight case-what wo
uld be the fate of other many hazardous drugs?
Let the government and Drug Controller of India
announce how they are going to make the ban effec
tive.

STUDY OF PAIN KILLERS (ANALGESICS & ANTIPYRETICS AND NSAIDS)
LISTED IN A COMMERCIAL PUBLICATION FOR DOCTOR'S USE.
Pain killers are a group of drugs that are most commonly used. This study is an
attempt to bring to the notice of the consumers regarding the type of pain killers
that are available for ; doctor to prescribe to the patient. Are the drugs promoted to
doctors’ from the list of Essential Drugs by WHO? Are the drugs scientific? And if
L the pricing °_f dr,lg? 's justified._____________________________________________
WHY THIS STUDY?
Pain is perhaps the most common symptom for which patients seek guidance ind
help from doctors Pain killers are a group of drugs that are extensively used both by
general practitioners and consultants.
Drug Action Forum - Karnataka (an independent, non-profit and non governmental organization campaigning for Rational drugs and policies) took up this
study, with an attempt to bring to the notice of the consumer, regarding the type of the
pain killers that are commonly promoted to doctors. A commercial publication used
exclusively by doctors was referred to get the common pain killers that are promoted by
various drug manufacturers.
The study is mainly aimed for consumer groups that are actively involved in
building awareness among consumers by involving in campaigning and lobbying for
rational drugs. It is hoped that the consumer groups would be better equipped to lobby for
rational drugs, when dealing with drug policy makers, w'ith studies of such nature
The study is relevant because in India, doctors after passing out from the medical
colleges have no access to unbiased and scientific information to them regarding drugs.
They are often compelled to depend upon the information that is given to them by drug
companies or at times by information that is supplied to them through company
sponsored seminars. Often drug companies promote irrational drugs to doctors. Using the
case study of pain killers, this study confirms the above statements.
Industry promotion - in the form of direct-mail brochures, journal, displays, professional
courtesies or detail person or pharmaceutical representatives - is intended to be
persuasive rather than educational.
The pharmaceutical industry cannot, should not, and indeed does not purport to be
responsible for the education of physicians in the use of drugs.
j Goodman & Gilman's, The Pliannaccutical basis of therapeutics. IO1*1 edition. Page number 64
The study is mainly under two heads:
i.
ii.
Rationality: - Does the drug listed in the commercial publication (MLMS), match
with the Essential Drug list by WHO? And is the drug rational?
The drug prices: - Comparing the Essential Drug prices set by different companies.
(1) Is the drug Essential and Rational?
For the sake of this study three publications have been used. One is a commercial
publication used by doctors extensively all over India and the other two are scientific
publications. Among the scientific publications one is the well known “WHO mode) list
of Essential Drugs”, first published in 1977 and has been regularly updated every two
years. The other scientific publication is “The Pharmacological Basis of Therapeutics”,
10dl edition by Goodman & Gilman, a standard text book which is used for reference and
study by academic medical professionals all over the globe
a) Monthly Index of Medical Specialities (MIMS)
The commercial publication is “Monthly Index of Medical Specialities” known
popularly by its acronym MIMS (www mims-india com). The June 2004, volume 24,
number 6 issue of MIMS'lists in its index, 90 groups of drugs under different categories.
But for the present study only two categories were selected Firstly Analgesics &
antipyretics and secondly NSAIDs (Analgesics is a term used for all categories of pain
killers. Antipyretics are drugs that reduce fever NSAIDs is an acronym for Non Steroidal
Anti-Inflammatory Drugs, a term used for all categories of drugs that reduce
inflammation and do not belong to the steroid group of drugs) All these analgesics &
antipyretics and NSAIDs are available in various forms (like tablets and syrups etc) and
also different dosage forms. Totally 235 formulations (manufactured by 49 drug
companies and sold under 120 brands) were systematically scrutinised with reference to
World Health Organization (WHO) Model List and a standard text book of
Pharmacology.
b) WHO Model List of Essential Drugs :-
The WHO Model list of Essential Drugs 2003 referred to in this study contains
about 375 drugs in 500 formulations (or dosage forms). These could provide safe,
effective treatment for the vast majority of communicable and non-communicable
diseases. Essential Drugs should be the drugs of first choice, more so in a situation where
financial resources are a crunch. The list was first published in 1977 by WHO and has
proven that most diseases can be managed with few medicines All the 235 drugs in our
study were checked to see whether they are included as Essential Drug or not.
OF THE TOTAL 235 FORMULATIONS LISTED FOR THIS STUDY ONLY 23
(9%) MATCHED WITH ESSENTLAL DRUGS.
Rationality
To assess whether the drug is rational or not, a standard text book of
Pharmacology, titled Goodman & Gilman's “The Pharmacological basis of Therapeutics”
was referred. This is a standard text book, used extensively by teachers and medical
students during medical teaching and training.
The term “ratic nal” is used for drugs that are scientific in nature by being referred
and recommended or mentioned in standard text books. Irrational drugs on the other hand
do not find mention or are not recommended in such text books. So with the help of the
text book the following two criteria were evolved:-
1. Firstly if the formulation is not mentioned in the book (for example combination
like Paracetamol with Ibuprofen) then it is considered as irrational
2. Secondly if the formulation is described but the text book does not advocate it, the
formulation is considered as irrational (for example Analgin or Nimesulide).
If a certain formulation does not fall under both the above mentioned criteria, it is
labeled as Rational drug
What is Rational drug?
If their efficacy is clinically proven and the therapeutic benefits outweigh the risks, they are called as
rational drugs
What is irrational drug?
If there is no good clinical pharmacological evidence on their therapeutic benefit and safety then, such
drugs are considered as irrational drugs.
The presence of irrational drugs is not only an economic burden but also can be harmful. This is truer
for developing country like India.
OF THE TOTAL 235 FORMULATIONS THAT WERE STUDIED A TOTAL OF
95 (40%). THUS THE NUMBER OF RATIONAL DRUGS ARE 140 (60%).
SUMMARY OF THE STUDY (part 1)
Of the total 235 formulations that were screened only 22 (9%) confirmed to the
Essential Drug list of WHO, 140 were (60%) rational drugs and remaining 95 (40%)
were irrational
Only one out of every ten drugs that are promoted to doctors confirm to WHO’s
Essential Drugs. And out of every ten drugs, six drugs are rational. From this it is obvious
that if a doctor prescribes a drug, there is only one in ten chances of prescribing the drug
of first choice. This is not an acceptable situation where financial resources are always a
major crunch.
Some interesting observations:- Following were some of the interesting observations
after the study.
1. A reputed (?) multinational company (Aventis) manufactures and sells the drug
Analgin. This drug is absolute as several safer alternatives exist.
2. Another hazardous (harmful) drug is Nimesulide. It is manufactured by 5 '
companies, and amongst them 4 companies manufacture the drug for use in
children too. This drug has never been allowed in USA and banned in several
European countries.
3. Diclofenac - a pain killer often usee by both specialists and general practitioners
is also manufactured in the form of injectable. The injectable form of this drug is
not mentioned in the standard text book (The Pharmacological Basis of
Therapeutics, 10th edition by Goodman & Gilman), that has been referred for this
study.
4. Aspirin - a popular and most commonly needed pain killer is not manufactured
by any drug company. Aspirin is listed in WHO’s list of Essential Drugs Only
one drug company i.e. Nicholas Piramol manufactures an irrational combination
of Aspirin (Acetyl Salicylic acid) 350 mg with Caffeine 20 mg under the trade
name Micropyrin. So this study observes that some drugs which are on the
WHO’s Essential Drugs list are not promoted to the doctors by any drug company.
In fact Aspirin should have been made available for the doctors’ to prescribe.
5. A combination of the drug Ibuprofen with Paracetamol is perhaps the most widely
used irrational combination. In this study 6 drug companies manufacture this drug
and most of them even have the preparation for use in children (in the form of
syrup). A question often raised by the consumer is that, why do doctors prescribe
such an irrational combinations. As mentioned above one factor is that such drugs
are heavily promoted by the drug companies to the doctors. During medical
education students are taught by the teachers that such combinations are irrational
and that they can be harmful to the patients, but as they start prescribing drugs to
patient, the flood of misinformation by companies overshadows the scientific
information.
(II) Cost analysis of Essential Drugs
The second part of the study analyses the cost of the Essential Drugs listed in
MIMS. This part of the study is important as it gives a picture to the consumer regarding
the cost of the drugs that should have been of top priority for a doctor to prescribe.
WHO’s Essential Drugs list has only three NSALDs viz. Paracetamol, Ibuprofen
and Aspirin. As Aspirin is not manufactured by any drug company we studied the pricing
of only two drugs i.e. Paracetamol and Ibuprofen.
Following are the highlights:a. Paracetamol 500 mg is manufactured by 6 drug companies. Amongst them 2 drug
companies (SKF and Nicholas Piramol, the former being a multinational)
manufacture and sell the same drug Paracetamol under two different brand names
with different pricing. There can be no scientific justification for this.
(For details refer to the chart on next page).

The lowest priced Paracetamol is for Rs 4.21 and the costliest is at Rs 13.50. A
whooping price difference of 69%. How does one explain such a huge price
difference? Drug companies spend lot of money in promoting a drug to the doctor
and this cost is recovered by hiking the price of the drug. Doctors are neither
taught during their student days nor do the drug companies mention its price (cost)
when they promote the drug to doctors. So doctors tend to prescribe the costliest.
Unfortunately the consumer also believes that a costly drug is better acting. The
consumer is not aware that one could buy the same drug of another company at a
much lower rate. Medicines are the only commodities in the market where the
buyer is not the chooser.
Drug pricing of Ibuprofen 400 mg did not show much variation.

SUMMARY OF THE STUDY (PART II)
Drug prices need to be regulated by governments. But this study shows that
Essential Drug prices show such wide variation. This is an area that needs further studies.
But suffice it to say that drug pricing is not properly regulated by the government. There
is an urgent need for consumer groups to be actively involved in bringing awareness on
this issue.
