ARTHROTEC vs FLURBIPROFEN SODIUM
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Arthrotec is a combination of diclofenac, a nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2) enzymes, reducing prostaglandin synthesis, and misoprostol, a synthetic prostaglandin E1 analog that protects the gastric mucosa by increasing mucus and bicarbonate secretion, enhancing mucosal blood flow, and promoting epithelial repair.
Non-selective cyclooxygenase (COX-1 and COX-2) inhibitor, thereby decreasing prostaglandin synthesis, which mediates inflammation, pain, and fever.
One tablet (diclofenac 50 mg / misoprostol 200 mcg) orally twice daily with food.
50 mg orally every 4 to 6 hours as needed; maximum 300 mg per day.

Diclofenac: ~2 hours (range 1-4 h); misoprostol: 20-40 minutes (acid metabolite 1.5 h). No accumulation with repeated dosing.
3-4 hours; in elderly or hepatic impairment may extend to 5-6 hours.
Renal: ~95% as metabolites (diclofenac: ~65% as glucuronide conjugates; misoprostol: ~80% as inactive metabolites). Biliary/fecal: <5%.
Renal: 70% as conjugates (glucuronide) and unchanged drug (<1%); biliary/fecal: minimal.
