Clopidogrel is a P2Y 12 platelet inhibitor indicated for: Acute coronary syndrome For patients with non–ST-segment elevation ACS (unstable angina [UA]/non-ST-elevation myocardial infarction [NSTEMI]), clopidogrel has been shown to reduce the rate of myocardial infarction (MI) and stroke. ( 1.1 ) For patients with ST-elevation myocardial infarction (STEMI), clopidogrel has been shown to reduce the rate of MI and stroke. ( 1.1 ) Recent MI, recent stroke, or established peripheral arterial disease. Clopidogrel has been shown to reduce the rate of MI and stroke. ( 1.2 ) 1.1 Acute Coronary Syndrome (ACS) • Clopidogrel is indicated to reduce the rate of myocardial infarction (MI) and stroke in patients with non–ST-segment elevation ACS (unstable angina [UA]/ non–ST -elevation myocardial infarction [NSTEMI]), including patients who are to be managed medically and those who are to be managed with coronary revascularization. Clopidogrel should be administered in conjunction with aspirin. • Clopidogrel is indicated to reduce the rate of myocardial infarction and stroke in patients with acute ST-elevation myocardial infarction (STEMI) who are to be managed medically. Clopidogrel should be administered in conjunction with aspirin. 1.2 Recent MI, Recent Stroke, or Established Peripheral Arterial Disease In patients with established peripheral arterial disease or with a history of recent myocardial infarction (MI) or recent stroke clopidogrel is indicated to reduce the rate of MI and …

Active pathological bleeding, such as peptic ulcer or intracranial hemorrhage ( 4.1 ) Hypersensitivity to clopidogrel or any component of the product ( 4.2 ) 4.1 Active Bleeding Clopidogrel is contraindicated in patients with active pathological bleeding such as peptic ulcer or intracranial hemorrhage. 4.2 Hypersensitivity Clopidogrel is contraindicated in patients with hypersensitivity (e.g., anaphylaxis) to clopidogrel or any component of the product [see Adverse Reactions (6.2) ] .

­ CYP2C19 inhibitors: Avoid concomitant use of omeprazole or esomeprazole. (5.1) Bleeding: Clopidogrel increases risk of bleeding. (5.2) Discontinuation: Premature discontinuation increases risk of cardiovascular events. Discontinue 5 days prior to elective surgery that has a major risk of bleeding. (5.3) Thrombotic thrombocytopenic purpura (TTP) has been reported. (5.4) Cross-reactivity among thienopyridines has been reported. (5.5) 5.1 Diminished Antiplatelet Activity in Patients with Impaired CYP2C19 Function Clopidogrel is a prodrug. Inhibition of platelet aggregation by clopidogrel is achieved through an active metabolite. The metabolism of clopidogrel to its active metabolite can be impaired by genetic variations in CYP2C19 [see Boxed Warning ] . The metabolism of clopidogrel can also be impaired by drugs that inhibit CYP2C19, such as omeprazole or esomeprazole. Avoid concomitant use of clopidogrel with omeprazole or esomeprazole because both significantly reduce the antiplatelet activity of clopidogrel [see Drug Interactions (7.1) ]. 5.2 General Risk of Bleeding P2Y12 inhibitors (thienopyridines), including clopidogrel, increase the risk of bleeding. P2Y12 inhibitors (thienopyridines), inhibit platelet aggregation for the lifetime of the platelet (7-10 days). Because the half-life of clopidogrel’s active metabolite is short, it may be possible to restore hemostasis by administering exogenous platelets; however, platelet transfusions within 4 hours of the loading dose …

8.1 Pregnancy Risk Summary Available data from cases reported in published literature and postmarketing surveillance with clopidogrel use in pregnant women have not identified any drug-associated risks for major birth defects or miscarriage [see Data]. There are risks to the pregnant woman and fetus associated with myocardial infarction and stroke [see Clinical Considerations]. No evidence of fetotoxicity was observed when clopidogrel was administered to pregnant rats and rabbits during organogenesis at doses corresponding to 65 and 78 times the recommended daily human dose [see Data]. The estimated background risk of major birth defects and miscarriage for the indicated populations is …
