How does Kaopectate and Pepto-Bismol work?
|Bismuth subsalicylate is an active ingredient in Kaopectate and Pepto-Bismol products. This drug displays anti-inflammatory action because it contains salicylic acid and also has antacid and mild antibiotic properties. The exact mechanism of antidiarrheal actions has not been established. General opinion is that antidiarrheal actions can is not only exceeded by stimulating absorption of electrolytes and fluids across the intestinal wall but also, when bismuth subsalicylate is hydrolyzed to salicylic acid, due inhibition prostaglandin synthesis responsible for intestinal hypermotility and inflammation. In addition, bismuth subsalicylate can also bind toxins produced by Escherichia coli. Both, bismuth subsalicylate and its metabolized products, bismuth hydroxide and bismuth oxychloride are believed to have bactericidal action. As an antacid, bismuth has weak antacid properties.|
Bismuth subsalicylate may cause a black stools and black tongue in some patients, when it gets in interaction with trace amounts of sulfur in saliva and gastrointestinal tract. This discoloration is harmless and temporary.
Until 2003, attapulgite was used as active ingredient in Kaopectate, before that product was reformulated with bismuth subsalicylate. Attapulgite is a magnesium aluminium phyllosilicate which only occurs in a type of clay soil typical for the Southeastern United States. When it is used as a medicine, it binds toxic substances and acids in the digestive tract reducing fluid loss from diarrhea and contributing to firmer stools. For that reason, it has often been used in antidiarrheal medications. In Canada, McNeil Consumer Healthcare continues to market kaopectate using attapulgite as the active ingredient.
