Abstract
The effects of a novel CCK-B/gastrin receptorantagonist, S-0509, on gastric acid secretion and thehealing of acetic acid ulcers in rats were examined.S-0509, orally administered 1, 6, and 12 hr prior to a 3-hr pylorus ligation, significantlyinhibited basal gastric acid secretion in both normalrats and rats with gastric ulcers. The inhibition wasnearly dose-related, persisted for more than 15 hr, and proved to be more potent in rats withulcers than in normal rats. In addition, S-0509 markedlyinhibited pentagastrin- and carbachol-stimulated acidsecretion in both normal rats and rats with ulcers, but failed to inhibit histamine-stimulatedsecretions. In chronic gastric fistula rats, S-0509 alsosignificantly inhibited pentagastrin- andcarbacholstimulated gastric acid secretion in adose-related manner, but had no effect onhistaminestimulated secretion. These effects werelargely similar to those observed with famotidine,although famotidine also inhibited histamine-stimulatedsecretion. A two-week treatment with S-0509 markedly enhanced thespontaneous healing of acetic acid ulcers and preventedthe delay in ulcer healing caused by indomethacin.Gastric secretion was significantly inhibited and the plasma gastrin level was increased in theanimals studied. It is concluded that S-0509 is apromising new antisecretory drug for the treatment ofpeptic ulcers.
