The H 2 receptor antagonists are a class of drugs used to block the action of histamine on parietal cells in the stomach, decreasing the production of acid by these cells. H 2 antagonists are used in the treatment of dyspepsia, although they have been surpassed in popularity by the more effective [1] proton pump inhibitors.

[ 8 ] There is evidence supporting its use for allergies, but second generation antihistamines such as ketotifen and loratadine have shown equal results ...
Like other H 2 receptor antagonists, lafutidine acts by preventing the secretion of gastric acid. [3] It also activates calcitonin gene-related peptide, resulting in the stimulation of nitric oxide (NO) and regulation of gastric mucosal blood flow, increases somatostatin levels also resulting in less gastric acid secretion, causes the stomach lining to generate more mucin, inhibits neutrophil ...
It is used for symptomatic relief of allergic symptoms caused by histamine release, including nasal allergies and allergic dermatosis. Mebhydrolin has been shown to magnify the performance-deficit effects of alcohol.
