Ranitidin - Pharmacology:

The H2 antagonists are competitive inhibitors of histamine at the parietal cell H2 receptor. They suppress the normal secretion of acid by parietal cells and the meal-stimulated secretion of acid. They accomplish this by two mechanisms: histamine released by ECL cells in the stomach is blocked from binding on parietal cell H2 receptors which stimulate acid secretion, and other substances that promote acid secretion (such as gastrin and acetylcholine) have a reduced effect on parietal cells when the H2 receptors are blocked.

Ranitidin for patients

Phenylketonurics: ZANTAC 25 EFFERdose Tablets contain phenylalanine 2.81 mg per 25 mg of ranitidine. ZANTAC 150 EFFERdose Tablets contain phenylalanine 16.84 mg per 150 mg of ranitidine. ZANTAC EFFERdose Tablets should not be chewed, swallowed whole, or dissolved on the tongue.

Ranitidin Interactions

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.

For information on drug interactions associated with ranitidine, refer to the ZANTAC ® package insert.

Ranitidin Contraindications

TRITEC is contraindicated in patients known to have hypersensitivity to ranitidine bismuth citrate or any of its ingredients.

For information on clarithromycin contraindications, see clarithromycin package insert.
