Misoprostol is a synthetic prostaglandin E1 analogue that has gastric antisecretory, mucosal protective and uterine contractibility properties. The antisecretory activity and uterine contractibility of Misoprostol is mediated through a class of high affinity E- type prostaglandin receptors on the surface of gastric parietal cells and uterus respectively. Misoprostol achieves cytoprotection by stimulation of gastric mucus secretion, duodenal bicarbonate secretion and gastric mucosal blood flow.
