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, thereby reducing pain, fever, and inflammation.
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.
200-400 mg orally every 4-6 hours as needed; maximum 1200 mg/day (OTC). For prescription: 400-800 mg orally 3-4 times daily; maximum 3200 mg/day.
One tablet (diclofenac 50 mg / misoprostol 200 mcg) orally twice daily with food.

2-4 hours (terminal elimination half-life in adults; prolonged in overdose or renal impairment: up to 8-12 hours)
Diclofenac: ~2 hours (range 1-4 h); misoprostol: 20-40 minutes (acid metabolite 1.5 h). No accumulation with repeated dosing.
Renal: ~95% (hepatic metabolites and conjugates, <1% unchanged); biliary/fecal: ~5%
Renal: ~95% as metabolites (diclofenac: ~65% as glucuronide conjugates; misoprostol: ~80% as inactive metabolites). Biliary/fecal: <5%.
