Description: Prasugrel is a prodrug that inhibits platelet activation and aggregation. The active metabolite irreversibly blocks the P2Y12 component of adenosine diphosphate (ADP) receptors on the platelet, which prevents activation of the GPIIb/IIIa receptor complex, thereby reducing platelet activation and aggregation.
Onset: Inhibition of platelet aggregation: <30 min (dose-dependent).
Absorption: Rapidly absorbed from the GI tract. Time to peak plasma concentration: Approx 30 min.
Distribution: Plasma protein binding: Approx 98%.
Metabolism: Undergoes hydrolysis in the intestines before being metabolised by CYP450 isoenzymes to the active metabolite (R-138727) which is further metabolised to 2 inactive compounds.
Excretion: Via urine (approx 68%) and faeces (approx 27%). Elimination half-life: Approx 7.4 hr.
Store at 25°C.
