Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Non-selective inhibition of cyclooxygenase (COX-1 and COX-2), reducing prostaglandin synthesis, thereby decreasing pain, inflammation, and fever.
Indomethacin is a nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2) enzymes, reducing synthesis of prostaglandins, which mediate inflammation, pain, and fever. It also has a direct effect on renal blood flow and platelet aggregation.
200-400 mg orally every 4-6 hours as needed; maximum 1200 mg/day without prescription.
75 mg orally once daily, extended-release capsules.

2-4 hours (terminal elimination half-life); in overdose or hepatic impairment, may be prolonged to >4 hours. Clinically, the short half-life supports dosing every 6-8 hours for acute pain.
Terminal half-life is 4.5 hours (range 2.6-11.2 hours) in young adults; prolonged in elderly (up to 16 hours) and in patients with renal or hepatic impairment.
Renal excretion of conjugated metabolites (approximately 90% of an administered dose) with less than 1% excreted unchanged. Biliary/fecal elimination accounts for less than 5%.
Approximately 50% renal (as unchanged drug and metabolites, primarily glucuronide conjugates), 33% biliary/fecal. Indomethacin undergoes enterohepatic recirculation.
