We examined the ability of two specific inhibitors of histidine decarboxylase, (s)-α-fluoromethylhistidine (FMHd) and (s)-α-fluoromethylhistamine (FMHm), to inhibit basal gastric acid secretion. The two highest doses of FMHd administered, 50 and 100 mg/kg, decreased basal gastric acid secretion and total secretion volume but did not affect intraluminal pH. FMHm decreased gastric acid secretion, raised intraluminal pH, and to a lesserdegree decreased total secretion volume. Neither compound changed the severity of gastric ulcers produced by cold restraint stress.
