CHILDREN'S ADVIL vs INDOCIN
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 prostaglandin synthesis. This leads to decreased pain, inflammation, and fever through peripheral and central mechanisms.
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 200-400 mg orally every 4-6 hours as needed; maximum 1200 mg/day without prescription.
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 1.9–2.3 hours in children. In neonates, half-life is prolonged (up to 6 hours). Clinical context: Requires dosing every 6–8 hours for sustained antipyresis.
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 conjugated metabolites (glucuronide and sulfate) accounts for ~90% of the administered dose. Less than 5% is excreted unchanged in urine. Biliary/fecal elimination is minor (<5%).
Renal (60% as unchanged drug and glucuronide conjugates), biliary/fecal (33% via enterohepatic circulation).
