Sucrafil O Gel Suspension 200 ml belongs to a group of medicine called ‘ulcer protectants’ primarily used to treat peptic ulcers or gastrointestinal ulcers. It also treats hyperacidity, heartburn, indigestion, and gastritis (inflammation of the stomach). The stomach is usually protected from the acid by a mucous layer. In some cases, due to excess acid production, the mucous layer gets eroded, which leads to complications like acidity and heartburn. A peptic ulcer is a sore on the stomach’s lining or the first part of the small intestine (duodenum). Ulcer or sores of the stomach region are called gastric ulcers, while the duodenum ulcer is known as a duodenal ulcer.
