Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2) enzymes, reducing prostaglandin synthesis, thereby exerting analgesic, anti-inflammatory, and antipyretic effects.
Naproxen is a nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase-1 (COX-1) and cyclooxygenase-2 (COX-2), thereby reducing the synthesis of prostaglandins involved in inflammation, pain, and fever.
Oral: 300-600 mg every 6-8 hours as needed; maximum 3200 mg/day.
250-500 mg orally twice daily; maximum 1.5 g/day. For extended-release: 750-1000 mg orally once daily.

Terminal elimination half-life 12-17 hours (mean 14 hours); permits twice-daily dosing. Half-life prolonged in elderly and hepatic impairment.
Primarily renal; approximately 90% of a dose is excreted in urine as glucuronide conjugates and unchanged drug; <2% excreted in feces.
Primarily renal (95% as unchanged naproxen and 6-O-desmethylnaproxen); <5% fecal via biliary excretion.
