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) enzymes, primarily COX-2, reducing prostaglandin synthesis, thereby exerting analgesic, anti-inflammatory, and antipyretic effects.
200–400 mg orally every 4–6 hours as needed; maximum 1200 mg/day.
Oral: 50 mg twice daily or 75 mg twice daily; maximum 150 mg/day. Topical: apply 4 times daily. IM: 75 mg once daily.

1.8 to 2.5 hours. The short half-life supports dosing every 4 to 6 hours for acute pain and fever.
Clinical Note
moderateDiclofenac + Gatifloxacin
"Diclofenac may increase the neuroexcitatory activities of Gatifloxacin."
Clinical Note
moderateDiclofenac + Rosoxacin
"Diclofenac may increase the neuroexcitatory activities of Rosoxacin."
Clinical Note
moderateDiclofenac + Levofloxacin
"Diclofenac may increase the neuroexcitatory activities of Levofloxacin."
Clinical Note
moderateDiclofenac + Trovafloxacin
"Diclofenac may increase the neuroexcitatory activities of Trovafloxacin."
Terminal elimination half-life ~2 h (diclofenac immediate-release); enterohepatic recirculation may produce secondary peaks. Clinical context: Short half-life requires multiple daily dosing for sustained effect.
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%.
Renal (65% as metabolites, <1% unchanged); biliary/fecal (35% as metabolites).
