Description

Misoprostol is a PGE1 analog with agonist activity mediated by EP2, EP3, and EP4 receptors.1,2,3,4 It has been shown to inhibit the formation of gastric lesions in rats (ED50 = 0.31 µg/kg),2 inhibit superoxide generation in human neutrophils (EC50 = 0.35 µM),3 and relax fetal rabbit ductus arteriosus (EC50 = 0.36 nM)4 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 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.1
