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, resulting in antipyretic, analgesic, and anti-inflammatory effects.
Diclofenac inhibits cyclooxygenase (COX-1 and COX-2) enzymes, reducing prostaglandin synthesis, thereby providing anti-inflammatory, analgesic, and antipyretic effects.
200-400 mg orally every 4-6 hours as needed; maximum 1200 mg/day without prescription, up to 3200 mg/day under medical supervision.
Oral: 50-100 mg every 8-12 hours; maximum 150 mg/day. IM: 75 mg once daily for up to 2 days. Topical gel: apply 2-4 g to affected area 4 times daily.

2-4 hours in children; prolonged in neonates (up to 30 hours) and hepatic impairment.
Terminal elimination half-life is approximately 2 hours (range 1.2–2.5 hours) for diclofenac; this short half-life supports multiple daily dosing. The half-life is not significantly altered in renal impairment but may be prolonged in hepatic disease.
Renal excretion of conjugated metabolites (75-80% as glucuronide and sulfate conjugates, <10% as unchanged drug); biliary/fecal elimination accounts for <5%.
Approximately 65% of a dose is excreted renally as unchanged drug and glucuronide conjugates, with about 35% eliminated via biliary/fecal routes as metabolites.
