title: Gastric antisecretory activity of 15(R)-15-methylprostaglandin E2, arbaprostil, in dogs.
abstract: The gastric antisecretory activity of 15(R)-15-methylprostaglandin E2 (arbaprostil) was compared with that of natural prostaglandin (PG) E2 in Pavlov pouch dogs. Arbaprostil significantly inhibited pentagastrin- and food-stimulated gastric secretion when it was administered directly into the pouch at a dose of 10-30 micrograms/pouch and 30-300 micrograms/pouch, respectively. Natural PGE2, however, was inactive up to 1000 micrograms/pouch. The data indicate that arbaprostil is a potent, long-acting orally active antisecretory drug that may be useful for the treatment of peptic ulcer disease.
