scienceMechanism of Action (How it works)

expand_more

Aciloc 300 Tablet works by blocking histamine H2 receptors on the acid-producing cells of the stomach. This reduces both basal and stimulated secretion of gastric acid, lowering the volume and acidity of stomach contents. By decreasing acid production, ranitidine helps relieve acid-related symptoms and allows irritated or ulcerated areas of the stomach and esophagus to heal.
