描述

Bismuth subsalicylate, sold under the brand name Pepto-Bismol, is an antacid medication used to treat temporary discomforts of the stomach and gastrointestinal tract, such as diarrhea, indigestion, heartburn and nausea. Commonly known as pink bismuth, it is also sometimes the active ingredient in Kaopectate. Bismuth subsalicylate has the empirical chemical formula of C7H5BiO4, and it is a colloidal substance obtained by hydrolysis of bismuth salicylate (Bi{C6H4(OH)CO2}3). The actual structure is unknown and the formulation is only approximate. Recent evidence dictates that it is composed of a bismuth oxide core structure with salicylate ions attached to the surface. A model structure has recently been published having the composition Bi38O44{C6H4(OH)CO2}26.
