NCIt definition : A thienopyridine, with antiplatelet activity. Clopidogrel targets, irreversibly binds
to and alters the platelet receptor for adenosine diphosphate (ADP), thereby blocking
the binding of ADP to its receptor, inhibiting ADP-mediated activation of the glycoprotein
complex GPIIb/IIIa, and inhibiting fibrinogen binding to platelets and platelet adhesion
and aggregation. This results in increased bleeding time.;
