Prasugrel HCl
Prasugrel is an anti-platelet agent. The chemical name is 5-[(1RS)-2-cyclopropyl-1-(2-fluorophenyl)-2-oxoethyl]- 4,5,6,7-tetrahydrothieno[3,2-c]pyridin-2-yl acetate hydrochloride corresponding to the molecular formula C20H20FNO3S•HCl. Prasugrel is a prodrug, oxidation by intestinal and hepatic cytochrome P-450 enzymes convert prasugrel into its active metabolite. Its active form binds irreversibly to the adenosine diphosphate (ADP) P2Y12 receptor on platelets for their lifespan, thereby inhibiting their activation and decreasing subsequent platelet aggregation.
