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.

Ibuprofen 200-400 mg orally every 4-6 hours as needed; maximum 1200 mg/day without prescription.

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