ACTIONS AND CLINICAL PHARMACOLOGY
Ranitidine is an antagonist of histamine at gastric H
2
-receptor sites. Thus, ranitidine
inhibits both basal gastric secretion and gastric acid secretion
induced by histamine,
pentagastrin and other secretagogues. On a weight basis ranitidine is
between 4 and 9
times more potent than cimetidine. Inhibition of gastric acid
secretion has been observed
following intravenous, intraduodenal and oral administration of
ranitidine. This response
is dose-related, a maximum response being achieved at an oral dose of
300 mg/day.
Pepsin secretion is also inhibited but secretion of gastric mucus is
not affected. Ranitidine
does not alter the secretion of bicarbonate or enzymes from the
pancreas in response to
secretin and pancreozymin.
Ranitidine is rapidly absorbed after oral administration of 150 mg
ranitidine, peak plasma
concentrations (300 to 550 ng/mL)
occurred after
1 to 3 hours. Two distinct peaks or a
plateau in the absorption phase result from reabsorption of drug
excreted into the
intestine. These plasma concentrations are not significantly
influenced by the presence of
food in the stomach at the time of the oral administration nor by
regular doses of
antacids.
Bioavailability of oral ranitidine is approximately 50% to 60%
