An antacid tablet is taken when you suffer from acidity because it contains alkaline substances (bases) that neutralize the excess stomach acid. This neutralization reaction reduces the acidity in the stomach, which helps to relieve symptoms like heartburn, indigestion, and the burning sensation caused by excessive stomach acid. By chemically neutralizing the acid, antacids reduce irritation and protect the stomach lining from damage, providing quick relief from discomfort.
How Antacids Work
- Antacids contain bases such as magnesium hydroxide, aluminum hydroxide, calcium carbonate, or sodium bicarbonate.
- When these bases react with the excess hydrochloric acid in the stomach, they form water and a salt, thereby neutralizing the acid (a neutralization reaction).
- This action decreases the acidity in the stomach, alleviating symptoms associated with acid overproduction like heartburn or indigestion.
Medical Role
- Antacids provide symptomatic relief from acidity and are effective for minor symptoms.
- They do not inhibit acid production but neutralize the acid already present.
- They also help reduce damage to the stomach lining and esophagus by lowering the acid concentration.
Common Uses
- Relief from heartburn, indigestion, sour stomach, and acid reflux.
- Sometimes used adjunctively in conditions involving excessive stomach acid.
Thus, an antacid tablet is taken to counteract stomach acidity quickly and ease discomfort caused by acidity-related conditions.
