In rat platelets, Prasugrel hydrochloride active metabolite inhibits in vitro platelet aggregation induced by adenosine ADP (10μM) with an IC50 value of 1.8 μM. Prasugrel hydrochloride acts faster and is significantly more potent than Clopidogrel in vivo. Prasugrel hydrochloride is an inactive prodrug that requires metabolic processing in vivo to generate the active antiplatelet metabolite. Prasugrel hydrochloride is rapidly absorbed from the gut. After oral administration of standard-loading doses of 60 mg, maximum plasma levels of the active metabolite are achieved within 1 h, effective, maximum inhibition of platelet aggregation at 1-2 h. |
