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 involved in pain, inflammation, and fever.
Nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2), reducing prostaglandin synthesis. This leads to anti-inflammatory, analgesic, and antipyretic effects.
Oral: 200-400 mg every 4-6 hours as needed; maximum single dose 400 mg, maximum daily dose 1200 mg for OTC use.
100 mg orally once daily, extended-release formulation. Maximum 150 mg/day (divided as 75 mg twice daily or 100 mg once daily).

Terminal elimination half-life is 2-4 hours in children; prolonged in neonates or hepatic impairment.
The terminal elimination half-life is approximately 2 hours. The extended-release formulation (XR) does not alter the half-life; it maintains prolonged therapeutic plasma concentrations with twice-daily dosing.
Renal excretion of conjugated metabolites (approximately 70-90%) and unchanged drug (<10%). Biliary/fecal excretion accounts for <10%.
Approximately 65% of a dose is excreted renally as unchanged drug and metabolites (primarily as glucuronide conjugates); about 35% is eliminated via bile in feces.
