Antacids neutralize (reduce) excess stomach acid to relieve heartburn, sour stomach, acid indigestion, and stomach upset. They can also be used to relieve the pain of stomach and duodenal ulcers. Some antacids contain simethicone, which reduces gas.

Our body works roughly between 7.3 to 7.5 pH range. Acidity means excess of acid level in stomach. Antacid contains basic salt. so when we take antacid it reacts with excess acid of stomach and neutralize.(neutralization reaction takes place between acid and base).Commonly used antacids contains at least one of these key ingredients: Calcium Carbonate, Magnesium Hydroxide, Aluminum Hydroxide and/or Sodium Bicarbonate.
