ANAPROX vs CHILDREN'S ADVIL
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 decreased pain, inflammation, and fever through peripheral and central mechanisms.
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 1.9–2.3 hours in children. In neonates, half-life is prolonged (up to 6 hours). Clinical context: Requires dosing every 6–8 hours for sustained antipyresis.
Renal excretion of metabolites (95%) and unchanged drug (<5%); biliary/fecal elimination minor (<5%).
Renal excretion of conjugated metabolites (glucuronide and sulfate) accounts for ~90% of the administered dose. Less than 5% is excreted unchanged in urine. Biliary/fecal elimination is minor (<5%).
