Combining Aspirin and Rivaroxaban is a major interaction and should generally be avoided without close medical supervision.
Combining aspirin with rivaroxaban significantly increases your risk of serious bleeding, including bleeding in the stomach or brain. This combination should generally be avoided unless specifically directed and closely monitored by your doctor.
Mechanism: Aspirin is an antiplatelet agent that irreversibly inhibits cyclooxygenase (COX-1), reducing thromboxane A2 production and impairing platelet aggregation. Rivaroxaban is a direct oral anticoagulant (DOAC) that directly inhibits Factor Xa, preventing thrombin generation and clot formation. The concurrent use of these agents leads to a synergistic inhibition of both primary hemostasis (platelet function) and secondary hemostasis (coagulation cascade), resulting in a substantially elevated risk of hemorrhage.

Rivaroxaban
Rivaroxaban is a selective inhibitor of FXa. It does not require a cofactor (such as Anti-thrombin III) for activity. Rivaroxaban inhibits free FXa and prothrombinase activity. Rivaroxaban has no direct effect on platelet aggregation, but indirectly inhibits platelet aggregation induced by thrombin. By inhibiting FXa, rivaroxaban decreases thrombin generation.
