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.
Diclofenac inhibits cyclooxygenase (COX-1 and COX-2) enzymes, reducing prostaglandin synthesis, thereby providing anti-inflammatory, analgesic, and antipyretic effects.
50 mg intravenously every 8 hours
Oral: 50-100 mg every 8-12 hours; maximum 150 mg/day. IM: 75 mg once daily for up to 2 days. Topical gel: apply 2-4 g to affected area 4 times daily.

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).
Terminal elimination half-life is approximately 2 hours (range 1.2–2.5 hours) for diclofenac; this short half-life supports multiple daily dosing. The half-life is not significantly altered in renal impairment but may be prolonged in hepatic disease.
Primarily renal (approximately 70% as unchanged drug and metabolites); biliary/fecal excretion accounts for about 30%.
Approximately 65% of a dose is excreted renally as unchanged drug and glucuronide conjugates, with about 35% eliminated via biliary/fecal routes as metabolites.
