CALDOLOR 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 synthesis of prostaglandins involved in inflammation, pain, 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.
800 mg IV every 8 hours as a 30-minute infusion; alternatively, 400 mg IV every 6 hours. Maximum daily dose: 2400 mg.
25 mg orally 2-3 times daily; maximum 200 mg/day. Intravenous: 0.5-1 mg/kg as single dose for ductus arteriosus closure.

2-4 hours (terminal half-life). Clinical context: Requires dosing every 6-8 hours for sustained effect; no accumulation with normal hepatic function.
Terminal elimination half-life approximately 4.5 hours (range 2.6–11.2 hours); prolonged in elderly and patients with hepatic impairment.
Renal (primarily as glucuronide conjugates and inactive metabolites; <10% unchanged). Biliary/fecal elimination is negligible.
Renal (60% as unchanged drug and glucuronide conjugates), biliary/fecal (33% via enterohepatic circulation).
