A new PGE1 analogue (CL115,574) III. Effects on gastric acid and mucus secretion in man.
CL115,574, an analogue of PGE1, is a potent inhibitor of gastric acid secretion in animals. The effects of this compound on gastric acid and mucus secretion were studied in 8 male volunteers. The compound was well tolerated, and its maximally effective antisecretory dose (750 micrograms) inhibited pentagastrin stimulated acid secretion by approximately 40% over a 2-hour period, with stimulation beginning one hour after the drug was orally administered. CL115,574 proved to have a significant and sustained effect upon the stimulation of mucus secretion into gastric juice. Considering the possible role that mucus may play in mucosal cytoprotection, CL115,574 because of its antisecretory and mucogenic actions may prove to be an important clinical anti-ulcer compound.
