ARTHROTEC vs CLINORIL
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.
Nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2), reducing prostaglandin synthesis, thereby exerting anti-inflammatory, analgesic, and antipyretic effects. Sulindac is a prodrug converted to the active sulfide metabolite.
One tablet (diclofenac 50 mg / misoprostol 200 mcg) orally twice daily with food.
150-200 mg orally twice daily, with maximum daily dose of 400 mg.

Diclofenac: ~2 hours (range 1-4 h); misoprostol: 20-40 minutes (acid metabolite 1.5 h). No accumulation with repeated dosing.
7.8 hours (terminal); clinical context: prolonged in elderly and renal impairment, requiring dose adjustment.
Renal: ~95% as metabolites (diclofenac: ~65% as glucuronide conjugates; misoprostol: ~80% as inactive metabolites). Biliary/fecal: <5%.
Renal: 50% as unchanged drug, 25% as glucuronide conjugate; Biliary/Fecal: 25% as metabolites.
