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.
Indomethacin is a nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2) enzymes, thereby reducing prostaglandin synthesis, which mediates inflammation, pain, and fever. It also decreases renal blood flow and may cause ductus arteriosus closure.
400 mg (two 200 mg Liqui-Gels) orally every 6 to 8 hours as needed; maximum 1200 mg per day.
25 mg orally 2-3 times daily; maximum 200 mg/day. Intravenous: 0.5-1 mg/kg as single dose for ductus arteriosus closure.

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 4.5 hours (range 2.6–11.2 hours); prolonged in elderly and patients with hepatic impairment.
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 (60% as unchanged drug and glucuronide conjugates), biliary/fecal (33% via enterohepatic circulation).
