MECLOFENAMATE SODIUM vs VOLTAREN-XR
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2), reducing prostaglandin synthesis. This leads to anti-inflammatory, analgesic, and antipyretic effects.
50 mg or 100 mg orally three times daily; maximum 400 mg/day.
100 mg orally once daily, extended-release formulation. Maximum 150 mg/day (divided as 75 mg twice daily or 100 mg once daily).

2-4 hours (terminal half-life; may be prolonged in hepatic impairment or elderly)
The terminal elimination half-life is approximately 2 hours. The extended-release formulation (XR) does not alter the half-life; it maintains prolonged therapeutic plasma concentrations with twice-daily dosing.
Renal (60-70% as metabolites and conjugates), biliary/fecal (20-30%)
Approximately 65% of a dose is excreted renally as unchanged drug and metabolites (primarily as glucuronide conjugates); about 35% is eliminated via bile in feces.
