ARTHROTEC vs EYDENZELT
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.
EYDENZELT (bexarotene) is a retinoid that selectively binds to and activates retinoid X receptors (RXRs), which regulate gene expression involved in cell differentiation, proliferation, and apoptosis. It induces apoptosis and inhibits cell growth in malignant T-cells.
One tablet (diclofenac 50 mg / misoprostol 200 mcg) orally twice daily with food.
1 mg subcutaneously once weekly.

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 approximately 12-14 hours, allowing once-daily dosing with steady-state reached within 3-5 days.
Renal: ~95% as metabolites (diclofenac: ~65% as glucuronide conjugates; misoprostol: ~80% as inactive metabolites). Biliary/fecal: <5%.
Primarily renal excretion as unchanged drug (approximately 70-80%) and minor fecal elimination (≤10%). Biliary excretion is negligible.
