Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Diclofenac epolamine inhibits cyclooxygenase (COX-1 and COX-2) enzymes, reducing prostaglandin synthesis and consequent inflammation, pain, and fever.
Celecoxib is a nonsteroidal anti-inflammatory drug (NSAID) that selectively inhibits cyclooxygenase-2 (COX-2), reducing prostaglandin synthesis involved in inflammation, pain, and fever. It has no significant inhibition of COX-1 at therapeutic doses.

Terminal elimination half-life is approximately 2-4 hours in adults with normal renal function; may be prolonged in renal impairment (up to 8-12 hours).
2-4 hours (terminal); clinical context: short half-life necessitates frequent dosing for sustained relief; prolonged in hepatic impairment
Primarily renal (approximately 70% as unchanged drug and metabolites); biliary/fecal excretion accounts for about 30%.
Renal: ~60% unchanged; biliary/fecal: ~30% as metabolites; remainder as glucuronide conjugates
