title: Clopidogrel bisulfate: in ST-segment elevation myocardial infarction.
abstract: Clopidogrel bisulfate (hereafter, clopidogrel), a selective inhibitor of ADP-induced platelet aggregation, is approved for the reduction of atherothrombotic events in patients with ST-segment elevation myocardial infarction (STEMI). In COMMIT/CCS-2, a well designed trial in 45,852 adult patients with STEMI, relative to aspirin alone, clopidogrel 75 mg/day plus aspirin treatment significantly reduced the risk of both coprimary endpoints: the composite endpoint of reinfarction, stroke, or death from any cause and the risk of death from any cause. Based on the findings of this trial, treating 1000 patients for approximately 2 weeks with clopidogrel is associated with nine fewer patient deaths, reinfarctions, or strokes during treatment. In CLARITY-TIMI 28, a well designed supportive study in 3491 adult patients with STEMI, clopidogrel plus aspirin reduced the odds that a composite primary endpoint event of an occluded infarct-related artery, recurrent myocardial infarction, or death from any cause would occur versus aspirin plus placebo. Clopidogrel treatment was generally well tolerated in these clinical trials, with no significant between-group difference in the rate of major bleeding in either trial. Experience in other patient populations (e.g. those with recent myocardial infarction, recent ischemic stroke, or established peripheral arterial disease) has shown that longer-term (< or =3 years) clopidogrel monotherapy is generally well tolerated.
