Side effects:
Clopidogrel has been evaluated for safety in more than 42,000 patients who have participated in
clinical studies, including over 9,000 patients treated for 1 year or more. The clinically relevant
adverse reactions observed in the CAPRIE, CURE, CLARITY and COMMIT studies are
discussed below. Overall, clopidogrel 75 mg/day was comparable to ASA 325 mg/day in
CAPRIE regardless of age, gender and race. In addition to clinical studies experience, adverse
reactions have been spontaneously reported.
Bleeding is the most common reaction reported both in clinical studies as well as in
postmarketing experience where it was mostly reported during the first month of treatment.
In CAPRIE, in patients treated with either clopidogrel or ASA, the overall incidence of any
bleeding was 9.3%. The incidence of severe cases was 1.4% for clopidogrel and 1.6% for ASA.
In CURE, the major bleeding event rate for clopidogrel+ASA was dose-dependent on ASA
(<100mg: 2.6%; 100-200mg: 3.5%; >200mg: 4.9%) as was the major bleeding event rate for
placebo+ASA (<100mg: 2.0%; 100-200mg: 2.3%; >200mg: 4.0%). The risk of bleeding
(life threatening, major, minor, other) decreased during the course of the trial: 0-1 months
(clopidogrel: 9.6%; placebo: 6.6%), 1-3 months (clopidogrel: 4.5%; placebo: 2.3%), 3-6 months
(clopidogrel: 3.8%; placebo: 1.6%), 6-9 months (clopidogrel: 3.2%; placebo: 1.5%), 9-12 months
(clopidogrel: 1.9%; placebo: 1.0%). There was no excess in major bleeds with clopidogrel +
ASA within 7 days after coronary bypass graft surgery in patients who stopped therapy more
than five days prior to surgery (4.4% clopidogrel+ASA vs. 5.3% placebo+ASA).
In patients who remained on therapy within five days of bypass graft surgery, the event rate was
9.6% for clopidogrel+ASA, and 6.3% for placebo+ASA.
In Clarity, there was an overall increase in bleeding in the clopidogrel + ASA group (17.4%) vs.
the placebo + ASA group (12.9%).The incidence of major bleeding was similar between groups
(1.3% versus 1.1% for the clopidogrel + ASA and the placebo + ASA groups, respectively). This
was consistent across subgroups of patients defined by baseline characteristics, and type of
fibrinolytic or heparin therapy.
In Commit, the overall rate of noncerebral major bleeding or cerebral bleeding was low and
similar in both groups (0.6% versus 0.5% in the clopidogrel + ASA and the placebo + ASA
groups, respectively).

Indication
Clopidogrel is indicated in adults for the prevention of atherothrombotic events in:
Patients suffering from myocardial infarction (from a few days until less than 35 days),
ischaemic stroke (from 7 days until less than 6 months) or established peripheral arterial
disease.
Patients suffering from acute coronary syndrome:
Non-ST segment elevation acute coronary syndrome (unstable angina or non-Q-wave
myocardial infarction), including patients undergoing a stent placement following
percutaneous coronary intervention, in combination with acetylsalicylic acid (ASA).
ST segment elevation acute myocardial infarction, in combination with ASA in medically
treated patients eligible for thrombolytic therapy.
Administration & Dosage
Adults and Elderly:
Clopidogrel should be given as a single daily dose of 75 mg with or without food.
The 300 mg tablet of clopidogrel is intended for use as a loading dose in patients suffering from
acute coronary syndrome:
− Non-ST segment elevation acute coronary syndrome (unstable angina or non-Q-wave
myocardial infarction): clopidogrel treatment should be initiated with a single 300-mg loading
dose and then continued at 75 mg once a day (with acetylsalicylic acid (ASA) 75 mg-325 mg
daily). Since higher doses of ASA were associated with higher bleeding risk it is recommended
that the dose of ASA should not be higher than 100 mg. The optimal duration of treatment has
not been formally established. Clinical trial data support use up to 12 months, and the maximum
benefit was seen at 3 months.
– ST segment elevation acute myocardial infarction: clopidogrel should be given as a single daily
dose of 75 mg initiated with a 300-mg loading dose in combination with ASA and with or
without thrombolytics. For patients over 75 years of age clopidogrel should be initiated without a
loading dose. Combined therapy should be started as early as possible after symptoms start and
continued for at least four weeks. The benefit of the combination of clopidogrel with ASA
beyond four weeks has not been studied in this setting.

Drug Interactions
Interaction with other medicinal products and other forms of interaction
Oral anticoagulants: The concomitant administration of clopidogrel with oral anticoagulants is
not recommended since it may increase the intensity of bleedings.
Glycoprotein IIb/IIIa inhibitors: Clopidogrel should be used with caution in patients who
receive concomitant glycoprotein IIb/IIIa inhibitors.
Acetylsalicylic acid (ASA): ASA did not modify the Clopidogrel-mediated inhibition of ADP
induced platelet aggregation, but Clopidogrel potentiated the effect of ASA on collagen-induced
platelet aggregation. However, concomitant administration of 500 mg of ASA twice a day for
one day did not significantly increase the prolongation of bleeding time induced by Clopidogrel
intake. A pharmacodynamic interaction between Clopidogrel and acetylsalicylic acid is possible,
leading to increased risk of bleeding. Therefore, concomitant use should be undertaken with
caution. However, Clopidogrel and ASA have been administered together for up to one year.
Heparin: In a clinical study conducted in healthy subjects, Clopidogrel did not necessitate
modification of the heparin dose or alter the effect of heparin on coagulation. Co-administration
of heparin had no effect on the inhibition of platelet aggregation induced by clopidogrel. A
pharmacodynamic interaction between Clopidogrel and heparin is possible, leading to increased
risk of bleeding. Therefore, concomitant use should be undertaken with caution.
Thrombolytics: The safety of the concomitant administration of clopidogrel, fibrin or non-fibrin
specific thrombolytic agents and heparins was assessed in patients with acute myocardial
infarction. The incidence of clinically significant bleeding was similar to that observed when
thrombolytic agents and heparin are co-administered with ASA
NSAIDs:
In a clinical study conducted in healthy volunteers, the concomitant administration of
clopidogrel and naproxen increased occult gastrointestinal blood loss. However, due to the lack
of interaction studies with other NSAIDs it is presently unclear whether there is an increased risk
of gastrointestinal bleeding with all NSAIDs. Consequently, NSAIDs including Cox-2 inhibitors
and clopidogrel should be co-administered with caution.
Other concomitant therapy: Since clopidogrel is metabolised to its active metabolite partly by
CYP2C19, use of medicinal products that inhibit the activity of this enzyme would be expected
to result in reduced drug levels of the active metabolite of clopidogrel. The clinical relevance of
this interaction is uncertain. As a precaution concomitant use of medicinal products that inhibit
CYP2C19 should be discouraged.
Medicinal products that inhibit CYP2C19 include omeprazole and esomeprazole, fluvoxamine,
fluoxetine, moclobemide, voriconazole, fluconazole, ticlopidine, ciprofloxacin, cimetidine,
carbamazepine, oxcarbazepine and chloramphenicol.
Proton Pump Inhibitors (PPI):
In a crossover clinical study, clopidogrel (300-mg loading dose
followed by 75 mg/day) alone and with omeprazole (80 mg at the same time as clopidogrel) were
administered for 5 days. The exposure to the active metabolite of clopidogrel was decreased by
45% (Day 1) and 40% (Day 5) when clopidogrel and omeprazole were administered together.
Mean inhibition of platelet aggregation (IPA) with 5 μM ADP was diminished by 39% (24
hours) and 21% (Day 5) when clopidogrel and omeprazole were administered together. In
another study it was shown that administering clopidogrel and omeprazole 12 hours apart did not
prevent their interaction that is likely to be driven by the inhibitory effect of omeprazole on
CYP2C19. Esomeprazole is expected to give a similar interaction with clopidogrel.
Inconsistent data on the clinical implications of this pharmacokinetic (PK)/pharmacodynamic
(PD) interaction in terms of major cardiovascular events have been reported from both
observational and clinical studies. As a precaution, concomitant use of omeprazole or
esomeprozole should be discouraged. No conclusive data on the pharmacodynamic interaction of
clopidogrel and other PPIs are available.
There is no evidence that other medicinal products that reduce stomach acid such as H2 blockers
(except cimetidine which is a CYP2C19 inhibitor) or antacids interfere with antiplatelet activity
of clopidogrel.
Other medicinal products:
A number of other clinical studies have been conducted with
clopidogrel and other concomitant medicinal products to investigate the potential for
pharmacodynamic and pharmacokinetic interactions. No clinically significant pharmacodynamic
interactions were observed when clopidogrel was co-administered with atenolol, nifedipine, or
both atenolol and nifedipine. Furthermore, the pharmacodynamic activity of clopidogrel was not
significantly influenced by the co-administration of phenobarbital or oestrogen.
The pharmacokinetics of digoxin or theophylline were not modified by the co administration of
clopidogrel. Antacids did not modify the extent of clopidogrel absorption.
Data from studies with human liver microsomes indicated that the carboxylic acid metabolite of
clopidogrel could inhibit the activity of Cytochrome P450 2C9. This could potentially lead to
increased plasma levels of medicinal products such as phenytoin and tolbutamide and the
NSAIDs, which are metabolised by Cytochrome P450 2C9. Data from the CAPRIE study
indicate that phenytoin and tolbutamide can be safely co-administered with Clopidogrel.
Apart from the specific medicinal product interaction information described above, interaction
studies with clopidogrel and some medicinal products commonly administered in patients with
atherothrombotic disease have not been performed. However, patients entered into clinical trials
with clopidogrel received a variety of concomitant medicinal products including diuretics, beta
blockers, ACEI, calcium antagonists, cholesterol lowering agents, coronary vasodilators,
antidiabetic agents (including insulin), antiepileptic agents, and GPIIb/IIIa antagonists without
evidence of clinically significant adverse interactions.
Precautions in usage
Bleeding and haematological disorders:
Due to the risk of bleeding and haematological adverse reactions, blood cell count determination
and/or other appropriate testing should be promptly considered whenever clinical symptoms
suggestive of bleeding arise during the course of treatment (see section 4.8). As with other
antiplatelet agents, clopidogrel should be used with caution in patients who may be at risk of
increased bleeding from trauma, surgery or other pathological conditions and in patients
receiving treatment with ASA, heparin, glycoprotein IIb/IIIa inhibitors or non-steroidal antiinflammatory
drugs (NSAIDs) including Cox-2 inhibitors. Patients should be followed carefully
for any signs of bleeding including occult bleeding, especially during the first weeks of treatment
and/or after invasive cardiac procedures or surgery. The concomitant administration of
clopidogrel with oral anticoagulants is not recommended since it may increase the intensity of
bleedings.
If a patient is to undergo elective surgery and antiplatelet effect is temporarily not desirable,
clopidogrel should be discontinued 7 days prior to surgery. Patients should inform physicians
and dentists that they are taking clopidogrel before any surgery is scheduled and before any new
medicinal product is taken. Clopidogrel prolongs bleeding time and should be used with caution
in patients who have lesions with a propensity to bleed (particularly gastrointestinal and
intraocular).
Patients should be told that it might take longer than usual to stop bleeding when they take
clopidogrel (alone or in combination with ASA), and that they should report any unusual
bleeding (site or duration) to their physician.
Thrombotic Thrombocytopenic Purpura (TTP):
Thrombotic Thrombocytopenic Purpura (TTP) has been reported very rarely following the use of
clopidogrel, sometimes after a short exposure. It is characterised by thrombocytopenia and
microangiopathic haemolytic anaemia associated with neurological findings, renal dysfunction or
fever. TTP is a potentially fatal condition requiring prompt treatment including plasmapheresis.
Recent ischaemic stroke:
In view of the lack of data, clopidogrel cannot be recommended during the first 7 days after
acute ischaemic stroke.
Cytochrome P450 2C19 (CYP2C19):
Contradictions
Hypersensitivity to the active substance, soya oil, peanut oil or to any of the excipients
• Severe liver impairment.
• Active pathological bleeding such as peptic ulcer or intracranial haemorrhage.
Overdosage
Overdose following clopidogrel administration may lead to prolonged bleeding time and
subsequent bleeding complications. Appropriate therapy should be considered if bleedings are
observed.
No antidote to the pharmacological activity of clopidogrel has been found. If prompt correction
of prolonged bleeding time is required, platelet transfusion may reverse the effects of
Clopidogrel.
Pharmaceutical Form: Film-coated tablet
Pharmacotherapeutic group: platelet aggregation inhibitors, ATC Code: B01AC 04.
Pharmacological properties:
Pharmacodynamics
Clopidogrel is a prodrug, one of whose metabolites is an inhibitor of platelet aggregation.
Clopidogrel must be metabolised by CYP450 enzymes to produce the active metabolite that
inhibits platelet aggregation. The active metabolite of clopidogrel selectively inhibits the binding
of adenosine diphosphate (ADP) to its platelet P2Y12 receptor and the subsequent ADP
mediated activation of the glycoprotein GPIIb/IIIa complex, thereby inhibiting platelet
aggregation.
Because the active metabolite is formed by CYP450 enzymes, some of which are polymorphic or
subject to inhibition by other drugs, not all patients will have adequate platelet inhibition.
Repeated doses of 75 mg per day produced substantial inhibition of ADP-induced platelet
aggregation from the first day; this increased progressively and reached steady state between
Day 3 and Day 7. At steady state, the average inhibition level observed with a dose of 75 mg per
day was between 40% and 60%. Platelet aggregation and bleeding time gradually returned to
baseline values, generally within 5 days after treatment was discontinued.
Pharmacokinetics
Absorption:
After single and repeated oral doses of 75 mg per day, clopidogrel is rapidly
absorbed. Mean peak plasma levels of unchanged clopidogrel (approximately 2.2-2.5 ng/ml after
a single 75 mg oral dose) occurred approximately 45 minutes after dosing. Absorption is at least
50%, based on urinary excretion of clopidogrel metabolites.
Distribution: Clopidogrel and the main circulating (inactive) metabolite bind reversibly in vitro
to human plasma proteins (98% and 954% respectively). The binding is non-saturable in vitro
over a wide concentration range.
Metabolism: Clopidogrel is extensively metabolised by the liver. In vitro and in vivo,
clopidogrel is metabolised according to two main metabolic pathways: one mediated by esterases
and leading to hydrolysis into its inactive carboxylic acid derivative (85% of circulating
metabolites), and one mediated by multiple cytochromes P450. Clopidogrel is first metabolised
to a 2-oxo-clopidogrel intermediate metabolite. Subsequent metabolism of the 2-oxo-clopidogrel
intermediate metabolite results in formation of the active metabolite, a thiol derivative of
clopidogrel. In vitro, this metabolic pathway is mediated by CYP3A4, CYP2C19, CYP1A2 and
CYP2B6. The active thiol metabolite which has been isolated in vitro, binds rapidly and
irreversibly to platelet receptors, thus inhibiting platelet aggregation.
Elimination:
Following an oral dose of 14C-labelled clopidogrel in man, approximately 50%
was excreted in the urine and approximately 46% in the faeces in the 120-hour interval after
dosing. After a single oral dose of 75mg, clopidogrel has a half-life of approximately 6 hours.
The elimination half-life of the main circulating metabolite was 8 hours after single and repeated
administration.
