Description of the drug approved by the manufacturer for the printed edition of 2017.


Antiulcer drug with bactericidal activity against Helicobacter pylori.
It also has an anti-inflammatory and astringent effect. In the acidic environment of the stomach, insoluble bismuth oxychloride and citrate are precipitated, and chelate compounds are also formed with the protein substrate as a protective film on the surface of ulcers and erosions. Increasing the synthesis of prostaglandin E, the formation of mucus and the secretion of bicarbonate, stimulates the activity of cytoprotective mechanisms, increases the resistance of the gastrointestinal mucosa to the effects of pepsin, hydrochloric acid, enzymes and bile salts. It leads to the accumulation of the epidermal growth factor in the defect area. Reduces the activity of pepsin and pepsinogen.
