Enprostil

Enprostil is a synthetic prostaglandin designed to resemble dinoprostone. Enprostil was found to be a highly potent inhibitor of gastric HCl secretion.[1] It is an analog of prostaglandin E2 but unlike this prostaglandin, which binds to and activates all four cellular receptors viz., EP1, EP2, EP3, and EP4 receptors, enprostil is a more selective receptor agonist in that it binds to and activates primarily the EP3 receptor.[2] Consequently, enprostil is expected to have a narrower range of actions that may avoid some of the unwanted side-effects and toxicities of prostaglandin E2. A prospective multicenter randomized controlled trial conducted in Japan found combining enprostil with cimetidine was more effective than cimetidine alone in treating gastric ulcer.[3]
