pharmacological action and mechanism | bismuth potassium citrate has a clear inhibitory effect on pepsin activity, but whether it can affect the secretion of pepsin is still controversial, and its role in neutralizing gastric acid is very weak. At present, it is believed that the role of bismuth potassium citrate is mainly to play a role locally. The specific mechanisms are as follows: ①Kill Helicobacter pylori (Hp) and reduce the pathogenic effect of Hp; ②Mucosal protection: strengthen the mucus barrier, non-specifically Inhibit the protease, lipase and glycosidase contained in Hp: Osmotic barrier effect, this product forms insoluble bismuth salt deposited on the gastric mucosa in an acidic environment, it is tightly combined with protein to form a bismuth peptide complex, which forms a protective film on the surface of the ulcer, which can isolate the erosion of gastric acid and enzymes on the ulcer, and has a protective effect on the gastric mucosa to prevent hydrogen ion infiltration. Stimulates endogenous prostaglandin synthesis. Stimulates the secretion of bicarbonate. When this product is applied for treatment, there is an accumulation of epidermal growth factor in the ulcer area. |
indications | bismuth potassium citrate is suitable for gastric ulcer, duodenal ulcer, anastomotic ulcer, chronic gastritis, erosive gastritis, duodenitis, functional dyspepsia, gastric mucosal damage caused by non-steroidal anti-inflammatory drugs, and anti-Helicobacter pylori infection. |
biological activity | Gastrodenol (Bismuth tripotassium dicitrate) is used to treat discomfort caused by excessive gastric acid, such as gastric ulcer and duodenal ulcer. |
use | gastric medicine can promote the regeneration of epithelial cells and kill helicobacter pylori completely and persistently |
