Azuranit

Azuranit - General Information

A non-imidazole blocker of those histamine receptors that mediate gastric secretion (H2 receptors). It is used to treat gastrointestinal ulcers.

Pharmacology of Azuranit

Azuranit is a histamine H2-receptor antagonist similar to cimetidine and famotidine. An H2-receptor antagonist, often shortened to H2 antagonist, is a drug used to block the action of histamine on parietal cells in the stomach, decreasing acid production by these cells. These drugs are used in the treatment of dyspepsia, however their use has waned since the advent of the more effective proton pump inhibitors. Like the H1-antihistamines, the H2 antagonists are inverse agonists rather than true receptor antagonists.

Azuranit 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.

Azuranit 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.

Azuranit 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.

Additional information about Azuranit

Azuranit Indication: Used in the treatment of peptic ulcer disease (PUD), dyspepsia, stress ulcer prophylaxis, and gastroesophageal reflux disease (GERD).
Mechanism Of Action: 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.
Drug Interactions: Anisindione The anti-H2 increases the anticoagulant effect
Dicumarol The anti-H2 increases the anticoagulant effect
Acenocoumarol The anti-H2 increases the anticoagulant effect
Warfarin The anti-H2 increases the anticoagulant effect
Itraconazole The anti-H2 decreases the absorption of the imidazole
Ketoconazole The anti-H2 decreases the absorption of the imidazole
Procainamide The histamine H2-receptor antagonist increases the effect of procainamide
Dasatinib Possible decreased levels of dasatinib
Atazanavir This gastric pH modifier decreases the levels/effects of atazanaivr
Tolazoline Anticipated loss of efficacy of tolazoline
Food Interactions: Avoid alcohol.
Avoid milk, calcium containing dairy products, iron, antacids, or aluminum salts 2 hours before or 6 hours after using antacids while on this medication.
Avoid excessive quantities of coffee or tea (Caffeine).
