Action: How Effient works
Effient belongs to the group of medicines called antiplatelet agents.
It works by reducing the ability of blood cells to clot. By preventing blood cells from clumping, it reduces the chances of blood clots forming (a process called thrombosis), thereby decreasing or even stopping the blood supply to the heart muscle.
Prasugrel is an inhibitor of platelet activation and aggregation through the irreversible binding of its active metabolite to the P2Y12 class of ADP receptors on platelets.
Effient contains either 5 mg or 10 mg of prasugrel (as hydrochloride) as the active ingredient.
It also contains mannitol, hypromellose, croscarmellose sodium, cellulose – microcrystalline, magnesium stearate, lactose, titanium dioxide, glycerol acetate, iron oxide yellow CI77492, and iron oxide red CI77491.
