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 decreased pain, inflammation, and fever through peripheral and central mechanisms.
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.
Ibuprofen 200-400 mg orally every 4-6 hours as needed; maximum 1200 mg/day without prescription.
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 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.
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 (glucuronide and sulfate) accounts for ~90% of the administered dose. Less than 5% is excreted unchanged in urine. Biliary/fecal elimination is minor (<5%).
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.
