Clopidogrel is a drug in the recently developed class of thienopyridine derivatives used to block adenosine diphosphate receptors on platelets, a blockade that results in the inhibition of platelet aggregation.1 The current use of clopidogrel is mainly to prevent stent restenosis in coronary artery disease and in the early and long-term prevention of atherothrombotic events.
