Other information

Indication
For the treatment of peptic or duodenal ulcers

Pharmacology
Ranitidine, a histamine H2-receptor antagonist similar to cimetidine and famotidine, is used to treat gastrointestinal disorders such as Helicobacter pylori-related peptic ulcer disease.

Mechanism Of Action
Ranitidine competes with histamine for binding at H2 receptors on gastric parietal cells. Competitive inhibition results in reduced basal and nocturnal gastric acid secretion. Ranitidine also decreases the amount of gastric acid released in response to stimuli such as food, caffeine, insulin, betazole, or pentagastrin. Other actions of ranitidine include an increase in gastric bacterial flora such as nitrate-reducing organisms.

Interactions
Interactions for Ranitidine:

Coadministration of TRITEC with clarithromycin resulted in increased plasma ranitidine concentrations (57%), increased plasma bismuth trough concentrations (48%), and increased 14- hydroxy- clarithromycin plasma concentrations (31%). Coadministration with aspirin results in a slight decrease in the rate of salicylate absorption that is clinically unimportant. Coadministration with a high dose of antacid (170 mEq) results in a 28% decrease in plasma concentrations of ranitidine and may decrease plasma concentrations of bismuth from TRITEC. These effects are clinically insignificant.
