Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Nonsteroidal anti-inflammatory drug (NSAID) that acts as a non-selective inhibitor of cyclooxygenase (COX-1 and COX-2), reducing prostaglandin synthesis. Its active metabolite, 6-methoxy-2-naphthylacetic acid (6MNA), is responsible for its therapeutic effects.
Nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2) enzymes, thereby reducing prostaglandin synthesis. This results in decreased inflammation, pain, and fever.
1000 mg orally once daily with food; may increase to 1500-2000 mg/day in divided doses if needed.
250-500 mg orally twice daily; maximum 1500 mg/day. For extended-release: 750-1000 mg orally once daily.

Terminal elimination half-life is approximately 22-30 hours in healthy adults, allowing once-daily dosing. Steady state is achieved after 3-5 days.
Terminal elimination half-life is 12-17 hours. This long half-life allows twice-daily dosing, but may lead to drug accumulation in elderly or renally impaired patients.
Approximately 80% of a dose is excreted in urine as metabolites (primarily 6-methoxy-2-naphthylacetic acid and its glucuronide conjugates), with about 10% excreted in feces. Biliary excretion is minimal.
Renal excretion of conjugated metabolites accounts for approximately 95% of a dose, with 1-2% as unchanged naproxen. Fecal excretion is minimal (<5%).
