Mechanism of Action
Calcium carbonate is a basic inorganic salt that helps neutralize hydrochloric acid in gastric secretions. It also inhibits the action of pepsin by increasing the pH and via adsorption. This may lead cytoprotective effects brought about by the increase in bicarbonate ion (HCO3-) and prostaglandins. The neutralization of hydrochloric acid then forms calcium chloride, carbon dioxide, and wate. Roughly 90% of calcium chloride is converted to insoluble calcium salts including calcium carbonate and calcium phosphate.
