Mechanism Of Action Colloidal bismuth subcitrate is very effective in the treatment of gastroduodenal disorders and appears to act via several mechanisms. It has little acid-neutralizing effect and does not affect acid secretion. It is uncertain whether it affects pepsin secretion, but it does inhibit peptic activity. It causes an increase in mucus glycoprotein secretion and may also bind to the gastric mucus layer to act as a diffusion barrier to HCl. It accelerates ulcer healing and causes an accumulation of epidermal growth factor around the ulcer. In addition, it has a cytoprotective effect and increases mucosal secretion of prostaglandins and bicarbonate. It has bactericidal effects against Helicobacter pylori (which is associated with gastritis and peptic ulcers) . It also prevents adhesion of H. pylori to epithelial cells and can inhibit enzymes secreted by H. pylori, such as proteases, lipases, glycosidases, and phospholipases.
Description of the Drug: Bismuth subcitrate potassium is a colloid used for the treatment of peptic ulcer and gastro-esophageal reflux disease (GERD) .
