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 synthesis of prostaglandins involved in inflammation, pain, and fever.
Reversible inhibition of cyclooxygenase (COX-1 and COX-2) leading to decreased prostaglandin synthesis; exhibits both central and peripheral analgesic effects.
800 mg IV every 8 hours as a 30-minute infusion; alternatively, 400 mg IV every 6 hours. Maximum daily dose: 2400 mg.
500 mg orally as an initial dose, followed by 250 mg every 6 hours as needed, not to exceed 1 week.

Terminal half-life is 2-4 hours; prolonged in hepatic impairment and overdose.
Renal (primarily as glucuronide conjugates and inactive metabolites; <10% unchanged). Biliary/fecal elimination is negligible.
Primarily renal (52% as glucuronide metabolites, <6% unchanged) and fecal (20-30% via biliary elimination).
