Prasugrel-d5 is intended for use as an internal standard for the quantification of prasugrel by GC- or LC-MS. Prasugrel is a prodrug form of the platelet purinergic P2Y12 receptor antagonist R-99224. Prasugrel (0.3 and 3 mg/kg) inhibits ex vivo washed platelet aggregation in rat platelet rich-plasma. In vivo, prasugrel prevents thrombus formation (ED50 = 0.68 mg/kg) and increases tail bleeding time in rats. Formulations containing prasugrel have been used in the prevention of blood clots.
