Full Answer

Although they share the name of antacids, indigestion medications are created from several different types of ingredients. Commonly, they exist as aluminum hydroxide, magnesium trisilicate or magnesium carbonate compounds. Some antacids also contain an ingredient called simeticone, which is used to reduce excess gas and bloating. Additionally, some antacids include ingredients called alginates, which are chemical substances that form a protective coating on the surface of the esophagus, to protect irritation and damage from strong stomach acids.

Regardless of chemical composition, antacids are available in different sizes and flavors, and are produced by a variety of brands. In addition to alleviating symptoms of heartburn and acid reflux, antacid tablets can also reduce pain and discomfort caused by ulcers, which typically form in the stomach and duodendum.
