DOMPERIDONE+RANITIDINE belongs to a group of medicines called gastrointestinal agents used to treat gastro-oesophageal reflux disease (GERD) and peptic ulcers. Gastroesophageal reflux disease (GERD) occurs when stomach acid frequently flows back into the food pipe (oesophagus). Peptic ulcers are sores that develop on the inner lining of the intestine and stomach. DOMPERIDONE+RANITIDINE is a combination of two drugs: Ranitidine and Domperidone. Ranitidine works by blocking histamine H2 receptors located on the stomach lining, thereby reducing gastric acid secretion. Domperidone works by increasing the movements and contractions of stomach muscles. Together, DOMPERIDONE+RANITIDINE helps in treating acidity.
