CLINICAL PHARMACOLOGY IN ADULTS
GI EFFECTS
Famotidine is a competitive inhibitor of histamine H receptors. The
primary clinically important
pharmacologic activity of famotidine is inhibition of gastric
secretion. Both the acid concentration and
volume of gastric secretion are suppressed by famotidine, while
changes in pepsin secretion are
proportional to volume output.
In normal volunteers and hypersecretors, famotidine inhibited basal
and nocturnal gastric secretion, as
well as secretion stimulated by food and pentagastrin. After oral
administration, the onset of the
antisecretory effect occurred within one hour; the maximum effect was
dose-dependent, occurring
within one to three hours. Duration of inhibition of secretion by
doses of 20 and 40 mg was 10 to 12
hours.
Single evening oral doses of 20 and 40 mg inhibited basal and
nocturnal acid secretion in all subjects;
mean nocturnal gastric acid secretion was inhibite
