Aspirin

Primary Antithrombotic Effect of Aspirin
  • Inhibits COX-1 (cyclooxygenase) completely
  • COX-1 is then unable to catalyze the oxygenation of arachidonic acid to prostaglandin G2
  • Lack of prostaglandin G2 blocks Thromboxane A2, which is responsible for platelet aggregation and vasoconstriction [1]
