DICLOFENAC vs MECLOFENAMATE SODIUM
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Diclofenac inhibits cyclooxygenase (COX) enzymes, primarily COX-2, reducing prostaglandin synthesis, thereby exerting analgesic, anti-inflammatory, and antipyretic effects.
Meclofenamate sodium 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.
Oral: 50 mg twice daily or 75 mg twice daily; maximum 150 mg/day. Topical: apply 4 times daily. IM: 75 mg once daily.
50 mg or 100 mg orally three times daily; maximum 400 mg/day.

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.
