Combining Aspirin and Prasugrel is a major interaction and should generally be avoided without close medical supervision.
Combining aspirin with prasugrel significantly increases your risk of bleeding, including serious and life-threatening bleeding episodes, because both medications thin your blood.
Mechanism: Aspirin irreversibly inhibits cyclooxygenase-1 (COX-1), preventing thromboxane A2 production and platelet aggregation. Prasugrel is a prodrug that, once metabolized, irreversibly binds to the P2Y12 receptor on platelets, inhibiting ADP-induced platelet activation and aggregation. The concurrent use of two antiplatelet agents leads to a synergistic inhibition of platelet function.
