INDOCIN SR vs ORUDIS KT
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.
Ketoprofen is a nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2), thereby reducing prostaglandin synthesis, which mediates 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.
Terminal elimination half-life: 2-4 hours (increased in elderly and renal impairment, up to 12 hours).
Approximately 50% renal (as unchanged drug and metabolites, primarily glucuronide conjugates), 33% biliary/fecal. Indomethacin undergoes enterohepatic recirculation.
Renal (approximately 60-80% as metabolites, <10% unchanged); biliary/fecal (approximately 20-35%).
