- Works by inhibiting the COX (cyclooxyrgenase) enzymes, which convert arachidonic acid to prostaglandin H2 (PGH2).
- PGH2, is converted to several other prostaglandins (which are mediators of pain, inflammation, and fever)
- Also converted to thromboxane A2 which stimulates platelet aggregation, leading to the formation of blood clots.
- Non-selective COX inhibition of 1 & 2.

- Antipyretic effects may be due to action on the hypothalamus = increased peripheral blood flow, vasodilation, and heat dissipation
