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.

Terminal elimination half-life is approximately 12–17 hours (mean ~14 hours), allowing twice-daily dosing. Steady-state is achieved after 4–5 doses.
Terminal elimination half-life is approximately 5 hours (range 4-6 hours) in healthy adults; prolonged in renal impairment.
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: approximately 90% as metabolites and conjugates; biliary/fecal: minor (less than 10%)
