Lafutidine HCl

    WARNING: This product is for research use only, not for human or veterinary use.

MedKoo CAT#: 598231

CAS#: Unknown (HCl)

Description: Lafutidine is a second generation histamine H2 receptor antagonist having multimodal mechanism of action and used to treat gastrointestinal disorders. It is marketed in Japan and India. Like other H2 receptor antagonists it prevents the secretion of gastric acid. 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 activation thus preventing injury from inflammation, and blocks the attachment of H. pylori to gastric cells.
