Which medication contains bismuth subsalicylate?

Bismuth subsalicylate is an active ingredient specifically known for its use in treating upset stomach, nausea, heartburn, indigestion, and diarrhea. Pepto-Bismol is the most recognizable brand that contains bismuth subsalicylate, making it a well-known product for gastrointestinal relief.

Maalox and Maalox Multi Action primarily contain ingredients aimed at neutralizing stomach acid, such as aluminum hydroxide and magnesium hydroxide, and they do not contain bismuth subsalicylate. Gravol is used for motion sickness and nausea and does not contain bismuth subsalicylate either.

Given this context, the identification of Pepto-Bismol as a medication containing bismuth subsalicylate is crucial for recognizing the specific applications of this ingredient in treatment. This knowledge helps pharmacy technicians understand how to effectively advise patients on appropriate medications for gastrointestinal issues, making Pepto-Bismol the correct answer in this case.
