Aspirin's anti-thrombotic effect is mediated by inhibition of blood platelets by blocking a platelet enzyme cyclooxygenase. Inhibition of this enzyme blocks the production of an important prothrombotic agent known as Thromboxane A2. Thromboxane causes activation and aggregation of platelets which is an early stage for thrombosis.
