Medicine Description zantac 300mg
Zantac 300mg Tablets is a medication that contains ranitidine, which functions as a competitive antagonist of the H2 histamine receptors located on the parietal cells of the stomach lining. By blocking these receptors, ranitidine inhibits the action of histamine, a chemical that stimulates the secretion of gastric acid. This action effectively decreases the overall production of stomach acid, thereby providing relief from conditions associated with excessive acidity, such as ulcers and gastroesophageal reflux disease (GERD). The reduction in acid secretion promotes healing of the gastrointestinal mucosa and alleviates symptoms like heartburn and discomfort.
