Nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2), reducing prostaglandin synthesis, which mediates pain, inflammation, and fever.

Terminal elimination half-life: 10-20 hours; context: allows twice-daily or once-daily dosing for chronic pain or inflammation.
Terminal half-life approximately 5-6 hours; clinical context: dosing every 6-8 hours required due to relatively short half-life; steady-state achieved within 24-30 hours.
Renal: 50-60% as metabolites and conjugates; biliary/fecal: ~5%; remainder uncharacterized.
Renal (90-95% as unchanged drug and metabolites, primarily glucuronide conjugates); biliary/fecal (minor, <5%).
