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, reducing synthesis of prostaglandins, which mediate inflammation, pain, and fever. It also has a direct effect on renal blood flow and platelet aggregation.
Nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2), thereby reducing prostaglandin synthesis, leading to decreased inflammation, pain, and fever.

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.
5-9 hours (terminal elimination half-life); in elderly or renal impairment, may extend up to 20 hours; clinical context: dosing adjustments recommended in renal impairment.
Approximately 50% renal (as unchanged drug and metabolites, primarily glucuronide conjugates), 33% biliary/fecal. Indomethacin undergoes enterohepatic recirculation.
Primarily renal excretion of metabolites (60-80%) with less than 1% unchanged drug; biliary/fecal excretion accounts for 20-40%.
