Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Misoprostol is a synthetic prostaglandin E1 analog that binds to prostanoid receptors, leading to inhibition of gastric acid secretion (both basal and stimulated) and increased mucus and bicarbonate secretion, providing mucosal protection. Additionally, it stimulates uterine contractions and cervical ripening.
Travoprost is a synthetic prostaglandin F2α analog that acts as a selective FP receptor agonist. By binding to FP prostanoid receptors, it increases uveoscleral outflow of aqueous humor, reducing intraocular pressure.
200 mcg orally four times daily with food for prevention of NSAID-induced gastric ulcers. For termination of pregnancy: 800 mcg vaginally every 12-24 hours or 600 mcg orally as a single dose.
One drop of 0.004% ophthalmic solution in the affected eye(s) once daily in the evening.

Terminal elimination half-life of misoprostol acid is approximately 20-40 minutes. Due to rapid de-esterification, the half-life of the prodrug is very short (<5 minutes). No accumulation occurs with repeated dosing. In patients with renal impairment, half-life may be prolonged (up to 80 minutes) and dose adjustment may be necessary.
Terminal elimination half-life is approximately 45 minutes (range 17–86 minutes) for travoprost free acid in plasma; clinical effect (IOP reduction) persists longer due to prolonged receptor binding.
Following oral administration, misoprostol is rapidly de-esterified to misoprostol acid, the active metabolite. Renal excretion of misoprostol acid is approximately 64-73% of the dose (with 11-17% as unchanged acid) over 24 hours. Fecal excretion accounts for about 15% of the dose, primarily as metabolites. Biliary excretion is minimal. The remainder is eliminated as unidentified metabolites.
Renal (approximately 20% as unchanged drug and free acid metabolites); biliary/fecal (about 60% as metabolites)
