Tums contain calcium cabronate. Calcium carbonate works by binding to excess acid produced by the stomach. This neutralises the acid and decreases the acidity of the stomach contents

Antacids are medications that increase the pH balance in your stomach. A number of symptoms, including heartburn, gastritis, and gastroesophageal reflux disease (GERD), can be treated with them. In most cases, antacids start working within a few minutes. It is important to note that they may not always be necessary, and they can have serious consequences if used improperly.
