Placebo & Aspirin
Aspirin inhibits platelet aggregation by irreversibly blocking cyclooxygenase (COX) enzymes, reducing thromboxane A2 production and preventing clot formation.
Aspirin inhibits platelet aggregation by irreversibly blocking cyclooxygenase (COX) enzymes, reducing thromboxane A2 production and preventing clot formation. Used for Cardiovascular event prevention (secondary prevention post-myocardial infarction or stroke), Acute coronary syndrome.

Mechanism of action
Aspirin acetylates serine residues on COX-1 and COX-2 enzymes, permanently inactivating them and preventing the synthesis of thromboxane A2 in platelets. This reduces platelet activation and aggregation, thereby decreasing the risk of thrombotic events. The placebo component serves as a control in clinical trials to assess the true efficacy of aspirin.
