Lafutidine is used to treat conditions caused by excess stomach acid, such as acid reflux and stomach ulcers. It belongs to a class of medicines called H2 receptor antagonists, which help reduce the amount of acid the stomach produces.
Lafutidine is commonly used for:
• Gastric and duodenal ulcers: Helps heal ulcers in the stomach and the first part of the small intestine by reducing acid production.
• Gastro-oesophageal reflux disease (GERD): Relieves heartburn and acid reflux caused by stomach acid flowing back into the food pipe.
• Acid-related dyspepsia: Eases indigestion, stomach discomfort, and bloating linked to excess stomach acid.
• Gastric mucosal lesions associated with acute gastritis and acute exacerbation of chronic gastritis: Helps improve gastric mucosal damage by reducing acid secretion and supporting the stomach's protective mechanisms.

Lafutidine works by reducing the amount of acid produced by the stomach.
The stomach lining contains cells that release acid to help digest food. This process is partly controlled by histamine acting on H2 receptors on these cells. Lafutidine blocks these H2 receptors, which reduces the signal for acid release.
Lafutidine also has an additional protective action, helping to increase blood flow to the stomach lining and support the mucous layer that protects it from acid damage.
By lowering acid production and supporting the stomach's natural defences, Lafutidine helps relieve symptoms of acid reflux and allows ulcers in the stomach lining to heal.
