Misoprostol Acid

Description

Misoprostol is a prostaglandin E₁ analog with agonist activity mediated by EP₂, EP₃, and EP₄ receptors. It has been shown to inhibit the formation of gastric lesions in rats (ED₅₀ = 0.31 μg/kg), inhibit superoxide generation in human neutrophils (EC₅₀ = 0.35 μM), and relax fetal rabbit ductus arteriosus (EC₅₀ = 0.36 nM) in a concentration dependent manner. Misoprostol is commonly used in clinical medicine for the prevention of peptic ulcer disease. It has also been used in conjunction with mifepristone (RU-486; ) for the oral induction of first trimester abortion. Misoprostol contains a C-1 methyl ester and is readily absorbed and rapidly hydrolyzed in humans to the active free acid.

Biochem/physiol Actions

Misoprostol is a synthetic prostaglandin E1 (PGE1) analogue use to prevent non steroidal anti inflammatory drug-induced (NSAID) gastric ulcers; as a labor inducing and postpartum hemorrhage treatment agent.
