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.
Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2) enzymes, reducing prostaglandin synthesis. This leads to 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
Ibuprofen 200-400 mg orally every 4-6 hours as needed; maximum 1200 mg/day without prescription.

Terminal elimination half-life 12-17 hours; prolonged in elderly (up to 20 hours) and in renal impairment.
Terminal elimination half-life is approximately 2-4 hours in children. Clinical context: rapid clearance; requires frequent dosing every 6-8 hours for sustained antipyretic/analgesic effect.
Renal excretion of metabolites (95%) and unchanged drug (<5%); biliary/fecal elimination minor (<5%).
Renal excretion of conjugated metabolites (glucuronides and sulfates) accounts for >90% of an administered dose, with <1% excreted unchanged. Biliary/fecal elimination is minimal (<5%).
