<unk>  is a thienopyridine which, when metabolized by the body, irreversibly blocks the P2Y12 component of the ADP receptor on the surface of platelets. Without ADP, fibrinogen does not bind to the platelet surface, preventing platelets from sticking to each other. By interfering with platelet function,<unk>  prevents clots from forming on the inside of blood vessels. Anti-platelet effects start within 2 days and reach their maximum by 6 days of therapy.<unk> ’s effects persist for 3 days after discontinuing<unk>  although it may take 1–2 weeks for platelet function to return to normal, as the medication affects platelets irreversibly. Therefore, new platelets must be formed before platelet function normalizes.
