Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Non-selective cyclooxygenase (COX-1 and COX-2) inhibitor, reducing prostaglandin synthesis and thereby decreasing inflammation, pain, and fever.
Diclofenac inhibits cyclooxygenase (COX-1 and COX-2) enzymes, reducing prostaglandin synthesis, thereby providing anti-inflammatory, analgesic, and antipyretic effects.
200–400 mg orally every 4–6 hours as needed; maximum 1200 mg/day.
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.

1.8 to 2.5 hours. The short half-life supports dosing every 4 to 6 hours for acute pain and fever.
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.
Renal excretion of metabolites and conjugates accounts for approximately 90% of an administered dose. Less than 1% is excreted unchanged. Biliary/fecal elimination accounts for about 10%.
Approximately 65% of a dose is excreted renally as unchanged drug and glucuronide conjugates, with about 35% eliminated via biliary/fecal routes as metabolites.
