ARTHROTEC vs CHILDREN'S IBUPROFEN
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, reducing prostaglandin synthesis, which mediates inflammation, pain, and fever.
One tablet (diclofenac 50 mg / misoprostol 200 mcg) orally twice daily with food.
Oral: 200-400 mg every 6-8 hours as needed; maximum daily dose: 1200 mg (OTC) or 3200 mg (prescription).

Diclofenac: ~2 hours (range 1-4 h); misoprostol: 20-40 minutes (acid metabolite 1.5 h). No accumulation with repeated dosing.
2-4 hours (terminal elimination half-life in children; may be prolonged in neonates or hepatic impairment)
Renal: ~95% as metabolites (diclofenac: ~65% as glucuronide conjugates; misoprostol: ~80% as inactive metabolites). Biliary/fecal: <5%.
Renal: 90% (primarily as conjugated metabolites, <10% unchanged); biliary/fecal: minor
