Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2), reducing prostaglandin synthesis, thereby decreasing pain, fever, and inflammation.
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.
200-400 mg orally every 6-8 hours as needed; maximum 1200 mg/day without prescription, extended release forms: 600-800 mg orally twice daily.
200-400 mg orally every 4-6 hours as needed; maximum daily dose 1200 mg.

2-4 hours in children; prolonged in neonates and hepatic impairment.
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).
Renal (90%) as inactive metabolites and conjugates; fecal (<5%).
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%).
