INDOCIN vs INFANT'S ADVIL
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2) enzymes, reducing prostaglandin synthesis. This leads to anti-inflammatory, analgesic, and antipyretic effects.
25 mg orally 2-3 times daily; maximum 200 mg/day. Intravenous: 0.5-1 mg/kg as single dose for ductus arteriosus closure.
200-400 mg orally every 4-6 hours as needed; maximum daily dose 1200 mg.

Terminal elimination half-life approximately 4.5 hours (range 2.6–11.2 hours); prolonged in elderly and patients with hepatic impairment.
Terminal elimination half-life is approximately 1.5 to 2 hours in infants and children, which is shorter than in adults (2-4 hours). This shorter half-life reflects higher clearance in pediatric populations and has clinical implications for dosing frequency (typically every 6-8 hours).
Renal (60% as unchanged drug and glucuronide conjugates), biliary/fecal (33% via enterohepatic circulation).
Renal excretion of metabolites (primarily glucuronide and sulfate conjugates of ibuprofen) accounts for approximately 90% of elimination, with less than 10% excreted unchanged in urine. Biliary/fecal excretion is minimal (<5%).
