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.
Non-selective COX-1 and COX-2 inhibitor, reducing prostaglandin synthesis via inhibition of cyclooxygenase, leading to anti-inflammatory, analgesic, and antipyretic effects.
400 mg (two 200 mg Liqui-Gels) orally every 6 to 8 hours as needed; maximum 1200 mg per day.
Oral: 50 mg two to three times daily; maximum 150 mg/day. Topical: 1% gel applied four times daily. Rectal: 100 mg suppository once daily.

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.
Terminal elimination half-life approximately 2 hours (range 1.3–3.1 h). Short half-life requires frequent dosing; no accumulation with normal dosing intervals.
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.
Approximately 65% renal as glucuronide conjugates and inactive metabolites, ~20% biliary/fecal. Less than 1% unchanged in urine.
