Arbaprostil is a synthetic prostaglandin E analog that protects gastric mucosa, prevents ulceration, and promotes healing of peptic ulcers. The protective effect is independent of acid inhibition. It is also a potent inhibitor of pancreatic function and can inhibit the growth of experimental tumors. Arbaprostil is a prodrug for the potent PGE2.
