Antacid action: Bismuth Subsalicylate coats ulcer surface, protecting it from acid and pepsin. It stimulates mucus and bicarbonate secretion and also reacts with HCl, produces bismuth oxychloride and salicylic acid thus reduces HCl.

Anti-diarrheal action: It stimulates absorption of water and electrolytes across the intestinal wall. In infectious diarrhea it binds with toxin produced by E.coli, disrupts cell, causing lysis of H.pylori and prevents adhesion of H.pylori in the cell wall of intestine.

Anti-inflammatory action: When hydrolyzed to salicylic acid, it inhibits prostaglandin G/H synthase ½. Thus reduces inflammation and Coats the irritated tissue to retard the expulsion of fluid.

Bismatol intoxication may also cause gastrointestinal disturbances, skin reactions, discoloration of mucous membranes, and renal dysfunction as a result of acute tubular necrosis. Treatment includes gastric lavage, purgation and hydration. Chelating agents may be effective in the early stages following ingestion and haemodialysis may be necessary. Overdose of Bismatol may also give symptoms of salicylate intoxification e.g. dizziness, tinnitus, sweating, nausea, headache. If symptoms occur, use of Bismatol  should be discontinued.
