INFANT'S ADVIL vs NAPROXEN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Naproxen is a nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase-1 (COX-1) and cyclooxygenase-2 (COX-2), thereby reducing the synthesis of prostaglandins involved in inflammation, pain, and fever.
200-400 mg orally every 4-6 hours as needed; maximum daily dose 1200 mg.
250-500 mg orally twice daily; maximum 1.5 g/day. For extended-release: 750-1000 mg orally once daily.

Terminal elimination half-life is approximately 1.5 to 2 hours in infants and children, which is shorter than in adults (2-4 hours). This shorter half-life reflects higher clearance in pediatric populations and has clinical implications for dosing frequency (typically every 6-8 hours).
Clinical Note
moderateNaproxen + Gatifloxacin
"Naproxen may increase the neuroexcitatory activities of Gatifloxacin."
Clinical Note
moderateNaproxen + Rosoxacin
"Naproxen may increase the neuroexcitatory activities of Rosoxacin."
Clinical Note
moderateNaproxen + Levofloxacin
"Naproxen may increase the neuroexcitatory activities of Levofloxacin."
Clinical Note
moderateNaproxen + Trovafloxacin
"Naproxen may increase the neuroexcitatory activities of Trovafloxacin."
Terminal elimination half-life 12-17 hours (mean 14 hours); permits twice-daily dosing. Half-life prolonged in elderly and hepatic impairment.
Renal excretion of metabolites (primarily glucuronide and sulfate conjugates of ibuprofen) accounts for approximately 90% of elimination, with less than 10% excreted unchanged in urine. Biliary/fecal excretion is minimal (<5%).
Primarily renal (95% as unchanged naproxen and 6-O-desmethylnaproxen); <5% fecal via biliary excretion.
