Aspirin is a prototypical cyclooxygenase (COX) inhibitor that irreversibly inhibits both COX-1 and COX-2, distinguishing it from reversible NSAIDs, thereby reducing thromboxane and prostaglandin synthesis. Its pharmacologic effects are dose-dependent, ranging from antiplatelet activity at low doses to antipyretic/analgesic effects at intermediate doses and anti-inflammatory effects at high doses, reflecting differential sensitivity of target tissues to prostaglandin suppression. This belongs to pharmacology, specifically the study of nonsteroidal anti-inflammatory drug mechanisms, dose-response relationships, and adverse drug effects mediated through prostaglandin pathways.
