WebDec 10, 2011 · The thienopyridines clopidogrel and prasugrel inhibit ADP-induced platelet aggregation. Prasugrel provides a more rapid and consistent response, resulting in higher levels of active metabolites compared with clopidogrel, but carries an increased risk of bleeding. 7 Both inhibit the platelet irreversibly, but unlike the case with aspirin, the … greatest common factor of 18 and 16
