Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Naproxen is a nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2) enzymes, reducing prostaglandin synthesis, which mediates inflammation, pain, and fever.
Non-selective inhibitor of cyclooxygenase (COX-1 and COX-2), decreasing prostaglandin synthesis, resulting in anti-inflammatory, analgesic, and antipyretic effects.
250-500 mg orally twice daily; maximum 1.5 g/day; for extended-release: 375-750 mg orally twice daily
200-400 mg orally every 4-6 hours, maximum 1200 mg/day; for OTC use, 200-400 mg every 6-8 hours as needed, maximum 1200 mg/day.

Terminal elimination half-life 12-17 hours; prolonged in elderly (up to 20 hours) and in renal impairment.
2.0-2.5 hours (terminal); no prolongation in mild hepatic impairment; increased in renal failure.
Renal excretion of metabolites (95%) and unchanged drug (<5%); biliary/fecal elimination minor (<5%).
Renal: 90% as metabolites and conjugates, <1% unchanged; biliary/fecal: minor.
