Plavix
What is Plavix?
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). 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. Adverse effects include bleeding, severe neutropenia, and thrombotic thrombocytopenic purpura.
Before the expiry of its patent, clopidogrel was the second best-selling drug in the world. In 2010, it grossed over US$9 billion in global sales.
