This article aims to answer that question and more as you find out several things about the famous drug Pepto Bismol, antacids, and their correlation with each other.

What Is Pepto Bismol?

Pepto Bismol is an over-the-counter medication with bismuth subsalicylate as its main ingredient. The drug or, more specifically, the component, helps with issues such as indigestion, diarrhea, nausea, and heartburn, among many things. It does this by protecting the lower part of your esophagus as well as your stomach from acid. The drug may come in two forms: (1) liquid and (2) tablet. In spite of its popularity, you can only get a Pepto Bismol from pharmacies.

Take note that Pepto Bismol is just one brand of bismuth subsalicylate. You can also find drugs with similar effects, as long as their active ingredient is bismuth subsalicylate.

What Can You Consider As An Antacid?

An antacid is any medication that can neutralize or counteract stomach acid. These drugs often come in tablet or liquid form, and they often assist with issues like acid reflux and indigestion.
