Bioactivity Bismuth Subsalicylate is a potent and orally active antacid and anti-diarrheal agent. Bismuth Subsalicylate reduces inflammation/irritation of stomach and intestinal lining through inhibition of prostaglandin synthesis in vivo[1]. Bismuth Subsalicylate is widely used for the research of diarrheal disorders, including indigestion, diarrhoea, nausea, et al[1][2].
In Vivo In the gastrointestinal tract, Bismuth Subsalicylate can be converted to salicylic acid and insoluble bismuth salts. Salicylic acid reduces inflammation/irritation of stomach and intestinal lining through inhibition of prostaglandin G/H synthase 1/2[1].Bismuth Subsalicylate (oral gavage; 100 mg/kg-350 mg/kg) significantly decreases castor oil-induced movement of a charcoal test meal along the small intestine of the mouse and rat and also decreases both the fecal output (dry or wet weight) and the frequency of diarrhea in mice[2].
