WebbThe first mechanism may occur due to a decrease in bioavailability caused by poor compliance, inappropriate dosing, a decrease in absorption, drug interaction, and the high metabolism of clopidogrel. Aside from bioavailability, gene polymorphism related to the P2Y12 receptor gene and CYP3A4, CYP1A2, CYP2C19 may also cause clopidogrel … WebbMechanism of action Prasugrel is a member of the thienopyridine class of ADP receptor inhibitors, like ticlopidine (trade name Ticlid) and clopidogrel (trade name Plavix). These agents reduce the aggregation ("clumping") of platelets by …

WebbClopidogrel, a potent novel platelet ADP-receptor antagonist, induces a significant inhibition of ADP-induced platelet aggregation. Maximum inhibition of 40 to 50% is observed 2 to 5 hours after a single 400 mg dose. The same level of inhibition is achieved with 75 mg once daily at steady state, i.e., after 3 to 7 days of repeated dosing. WebbMECHANISM OF ACTION; ...
