Mylanta and Pepto Bismol are two over-the-counter (OTC) medicines used to treat various gastrointestinal (GI) symptoms such as heartburn, indigestion, and diarrhea. Although these medications share some similarities, they also have distinct differences in terms of their active ingredients, indications, and mechanisms of action.

This article aims to provide a comprehensive comparison of Mylanta and Pepto Bismol, along with answering some of the most frequently asked questions about these two medications.

Explanation of Mylanta and Pepto Bismol

Mylanta is an antacid that contains two active ingredients, aluminum hydroxide and magnesium hydroxide, which work together to neutralize stomach acid and provide relief for heartburn, acid reflux, and other indigestion symptoms. Pepto Bismol, on the other hand, is an antidiarrheal medication that contains bismuth subsalicylate as its active ingredient. It works by coating the lining of the GI tract to alleviate diarrhea, upset stomach, and nausea.

Differences between Mylanta and Pepto Bismol

1. Active Ingredients

The main difference between Mylanta and Pepto Bismol lies in their active ingredients. Mylanta contains aluminum hydroxide and magnesium hydroxide, which work together to neutralize stomach acid and provide relief for heartburn, acid reflux, and other indigestion symptoms. Pepto Bismol, on the other hand, contains bismuth subsalicylate, which works as an antidiarrheal medication.

2. Indications

Mylanta is primarily used to relieve symptoms of acid indigestion, heartburn, and upset stomach. It may also be used to treat symptoms of gastro esophageal reflux disease (GERD). Pepto Bismol, on the other hand, is used to treat and prevent diarrhea, as well as other symptoms such as upset stomach, nausea, and heartburn.

3. Mechanism of action

Mylanta works by neutralizing stomach acid to relieve heartburn and other indigestion symptoms. The aluminum and magnesium ions in Mylanta react with the hydrochloric acid in the stomach to form aluminum chloride and magnesium chloride, which are less acidic and less irritating to the esophagus. Pepto Bismol, on the other hand, works by coating the lining of the stomach and intestines to reduce inflammation and irritation. It also has an antimicrobial effect and can kill certain bacteria that can cause diarrhea.

4. Forms of Administration

Mylanta is available in various forms, including liquid, chewable tablets, and gel caps. The liquid form is the most common, and it comes in different flavors. Pepto Bismol is also available in a liquid form, as well as chewable tablets and caplets.
