Sodium BicarbonateSodium bicarbonate is a rapid onset, short acting antacid which neutralises acid secretions in the gastrointestinal tract by reacting with hydrochloric acid to produce sodium chloride. During neutralisation carbon dioxide is released, facilitating erucation which provides a sense of relief. Calcium Carbonate Calcium carbonate is an antacid with a more prolonged effect than sodium bicarbonate. It rapidly reacts with gastric acid to produce calcium chloride.
Magnesium CarbonateMagnesium carbonate reacts with gastric acid to form soluble magnesium chloride and carbon dioxide. Because of its crystalline structure it reacts less rapidly than sodium bicarbonate giving it a slower onset of action, and providing longer lasting relief.
Sodium BicarbonateAdministration of sodium bicarbonate by mouth causes neutralisation of gastric acid with the production of carbon dioxide. Bicarbonate not involved in that reaction is absorbed and in the absence of a deficit of bicarbonate in the plasma, bicarbonate ions are excreted in the urine that is rendered alkaline with an accompanying diuresis. Calcium Carbonate Calcium carbonate is converted to calcium chloride by gastric acid. Some of the calcium is absorbed from the intestines but about 85% is reconverted to insoluble calcium salts, such as the carbonate and is excreted in the faeces.
Magnesium CarbonateMagnesium carbonate reacts with gastric acid to form soluble magnesium chloride and carbon dioxide in the stomach. Some magnesium is absorbed but is usually excreted rapidly in the urine.
