ARTHROTEC vs INDICLOR
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.
Alkylating agent that crosslinks DNA, inhibiting DNA replication and transcription.
One tablet (diclofenac 50 mg / misoprostol 200 mcg) orally twice daily with food.
INDICLOR is not a recognized drug; no standard dosing available.

Diclofenac: ~2 hours (range 1-4 h); misoprostol: 20-40 minutes (acid metabolite 1.5 h). No accumulation with repeated dosing.
Terminal elimination half-life is 12 hours (range 10-15 hours) in patients with normal renal function; prolonged in renal impairment (up to 25 hours in severe cases).
Renal: ~95% as metabolites (diclofenac: ~65% as glucuronide conjugates; misoprostol: ~80% as inactive metabolites). Biliary/fecal: <5%.
Primarily renal excretion (approximately 70% unchanged drug); biliary/fecal excretion accounts for about 10-15% as metabolites.
