NAPROXEN SODIUM vs PEDIATRIC ADVIL
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Non-selective cyclooxygenase (COX-1 and COX-2) inhibitor, reducing prostaglandin synthesis.
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.
220-550 mg orally twice daily; maximum 1375 mg/day.
Ibuprofen 200-400 mg orally every 4-6 hours as needed; maximum 1200 mg/day without prescription.

12–17 hours (terminal); allows twice-daily dosing; prolonged in elderly and 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: 95% (as unchanged drug, conjugated naproxen, and 6-O-desmethyl naproxen); Fecal: <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%).
