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.
Nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2), reducing prostaglandin synthesis, thereby exerting anti-inflammatory, analgesic, and antipyretic effects. Sulindac is a prodrug converted to the active sulfide metabolite.
550 mg orally every 8 to 12 hours; maximum 1375 mg/day.
150-200 mg orally twice daily, with maximum daily dose of 400 mg.

Terminal elimination half-life is approximately 12–17 hours (mean ~14 hours), allowing twice-daily dosing. Steady-state is achieved after 4–5 doses.
7.8 hours (terminal); clinical context: prolonged in elderly and renal impairment, requiring dose adjustment.
Renal elimination of naproxen and its metabolites accounts for approximately 95% of the dose, with about 60% as unchanged drug and 40% as conjugated or hydroxylated metabolites. Biliary/fecal excretion is negligible (<5%).
Renal: 50% as unchanged drug, 25% as glucuronide conjugate; Biliary/Fecal: 25% as metabolites.
