ARTHROTEC vs CHILDREN'S MOTRIN
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 decreasing pain, fever, and inflammation.
One tablet (diclofenac 50 mg / misoprostol 200 mcg) orally twice daily with food.
200-400 mg orally every 6-8 hours as needed; maximum 1200 mg/day without prescription, extended release forms: 600-800 mg orally twice daily.

Diclofenac: ~2 hours (range 1-4 h); misoprostol: 20-40 minutes (acid metabolite 1.5 h). No accumulation with repeated dosing.
2-4 hours in children; prolonged in neonates and hepatic impairment.
Renal: ~95% as metabolites (diclofenac: ~65% as glucuronide conjugates; misoprostol: ~80% as inactive metabolites). Biliary/fecal: <5%.
Renal (90%) as inactive metabolites and conjugates; fecal (<5%).
