MedKoo CAT#: 317556

CAS#: 120202-66-6 (sulfate)

Description: Clopidogrel (INN) is an oral, thienopyridine-class antiplatelet agent used to inhibit blood clots in coronary artery disease, peripheral vascular disease, cerebrovascular disease, and to prevent myocardial infarction (heart attack) and stroke. It is marketed by Bristol-Myers Squibb and Sanofi under the trade name Plavix. The drug works by irreversibly inhibiting a receptor called P2Y12, an adenosine diphosphate (ADP) chemoreceptor on platelet cell membranes. Clopidogrel acts by inhibiting the ADP receptor on platelet cell membranes. It is a prodrug, which requires CYP2C19 for its activation.
