Calcium carbonate is used as an antacid to relieve stomach heartburn, indigestion and other gastric problems. It can also be used as supplement in food in case of calcium deficiency (hypocalcemia).

 

What is calcium carbonate?

 

The calcium carbonate is an inorganic salt, which acts by neutralizing the gastric acids. The resulting increase in pH can inhibit the action of pepsin, an enzyme that digests proteins in gastric juice. Furthermore, the increase of bicarbonate ions and prostaglandins can exert a protective effect on cells.

 

How should calcium carbonate be taken?

 

In general, calcium carbonate is taken orally. The possible formulations include tablets, chewable tablets, capsules and solutions. Typically, the dosage varies from 3 to 4 times a day. In case of hypocalcemia it should be taken during or after meals.
