Many patients are unable to tolerate sufficient doses for complete phosphate control and require additional measures such as stringent dietary phosphate restriction or relatively small doses of aluminium hydroxide. Calcium Carbonate containing preparations can provide short-term relief of dyspeptic systems but are no longer recommended for long-term treatment of peptic ulceration.
Calcium Carbonate 1000 mg: This is indicated for the management of conditions associated with hyperidity and for fast relief of acid indigestion, heartburn, sour stomach and upset stomach.
CaCO3 + 2HCl = CaCl2 + H2O + CO2
Two grams of calcium carbonate will readily bring 100 ml of hydrochloric acid to a pH above 6. The increase in gastric pH diminishes the activity of pepsin in the gastric secretion. Up to 30% of the oral calcium load may be absorbed.
