Sucralfate is a locally acting gastroprotective medication. In the acidic environment of the stomach, it forms a viscous protective complex that preferentially binds to damaged mucosal tissue and ulcer surfaces. This protective barrier helps shield the affected area from hydrochloric acid, pepsin and bile acids, supporting the healing process.

Research and clinical evidence:
Sucralfate has been extensively studied as a treatment for peptic ulcer disease. Clinical research has demonstrated its ability to promote healing of gastric and duodenal ulcers through predominantly local protective activity. Unlike medications that directly suppress gastric acid production, sucralfate primarily acts by forming a physical and chemical barrier over damaged mucosa.
Clinical research has also evaluated sucralfate in various upper gastrointestinal conditions. However, treatment should be selected according to the underlying cause of disease. For example, sucralfate does not replace standard Helicobacter pylori eradication therapy when H. pylori infection is present. For significant acid-related disorders, a healthcare professional may instead select a proton pump inhibitor or another acid-suppressive treatment.
Sucralfate is primarily used for the treatment and prevention of recurrence of ulcerative lesions in the upper gastrointestinal tract, particularly duodenal ulcer disease.
Its main purpose is to protect damaged mucosa and create favorable conditions for ulcer healing. After administration, the medication interacts with proteins in damaged tissue and forms a protective layer that reduces exposure of the ulcer surface to gastric acid and digestive enzymes.
The suspension should be taken orally according to the healthcare professional's instructions. Sucralfate is generally administered on an empty stomach so that its protective action can occur directly at the mucosal surface. Appropriate spacing between sucralfate and other oral medications is important because sucralfate may reduce their absorption. The dose and duration of treatment should be determined by a healthcare professional based on the diagnosis and clinical condition.
