INDOCIN vs OXAPROZIN
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.
Oxaprozin is a nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2) enzymes, thereby reducing prostaglandin synthesis, which results in 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.
600-1200 mg orally once daily; maximum 1800 mg/day.

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 50–60 hours in healthy adults; clinical context: once-daily dosing achieves steady-state in 7–10 days.
Renal (60% as unchanged drug and glucuronide conjugates), biliary/fecal (33% via enterohepatic circulation).
Primarily hepatic metabolism (glucuronidation and hydroxylation) with renal excretion of metabolites; less than 1% excreted unchanged in urine; fecal elimination accounts for ~20%.
