title: Inhibition of pentagastrin-stimulated and overnight gastric secretion by LM24056, a new phenothiazine-derived antisecretory drug.
abstract: LM24056, a tricyclic drug, weakly inhibited pentagastrin-stimulated gastric secretion but was a powerful inhibitor of nocturnal gastric secretion in 5 healthy volunteers. In 23 patients with duodenal ulcer, LM24056 at doses of 100,200, and 300 mg inhibited overnight acid output by 31%, 70%, and 81%, and overnight pepsin secretion by 15%, 50%, and 69%, respectively. In view of its gastric inhibitory effects, LM24056 warrants clinical evaluation in the treatment of peptic ulcer disease.
