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) enzymes, reducing prostaglandin synthesis.
Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (Cox-1 and Cox-2) activity, reducing prostaglandin synthesis. This results in anti-inflammatory, analgesic, and antipyretic effects.
250-500 mg orally twice daily. Maximum 1500 mg/day.
200-400 mg orally every 4-6 hours as needed; maximum 1200 mg/day (OTC) or 3200 mg/day (prescription).

Terminal elimination half-life: 8-12 hours (dose-dependent; prolonged up to 15 hours with higher doses). Clinical context: allows twice-daily dosing; extended half-life in renal impairment.
Approximately 2 hours (range 1.5-3 hours) for the terminal elimination half-life in adults. Longer half-life in elderly and patients with renal impairment.
Renal: ~90% as glucuronide conjugates (diflunisal acyl glucuronide, diflunisal phenolic glucuronide); <5% unchanged. Biliary/fecal: minimal, <10%.
Renal elimination of conjugates and metabolites (90%) and biliary/fecal (10%). Unchanged drug excretion is negligible (<1%).
