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, thereby reducing the synthesis of prostaglandins involved in pain, inflammation, and fever.

400 mg (two 200 mg Liqui-Gels) orally every 6 to 8 hours as needed; maximum 1200 mg per day.
800 mg IV every 8 hours as a 30-minute infusion; alternatively, 400 mg IV every 6 hours. Maximum daily dose: 2400 mg.

Terminal elimination half-life is approximately 2 hours (range 1.8–3.5 hours). In clinical context, this short half-life supports dosing every 4–6 hours for acute migraine treatment, but drug effects may persist beyond this due to slow dissociation from COX enzymes.
2-4 hours (terminal half-life). Clinical context: Requires dosing every 6-8 hours for sustained effect; no accumulation with normal hepatic function.
Renal excretion of unchanged drug and metabolites accounts for approximately 90% of an administered dose, with about 10% excreted in feces via bile. Less than 1% is excreted unchanged in urine; the remainder as conjugates and oxidative metabolites.
Renal (primarily as glucuronide conjugates and inactive metabolites; <10% unchanged). Biliary/fecal elimination is negligible.
