Sodium Bicarbonate + Citric Acid + Sodium Carbonate

This is an antacid preparation that gives very fast relief from heartburn, indigestion, hyperacidity and flatulence. It works locally in the stomach and all its components are dissolved, so there is no need to look at its systemic bioavailability or pharmacokinetic behaviour. Any sodium and citrate ions left over for absorption are handled safely by the body and leave through the normal metabolic routes.

Sodium Bicarbonate + Citric Acid + Sodium Carbonate is an antacid. When the powder or tablet is put in a glass of water, the components react to form sodium citrate, which has antacid buffering properties, and carbon dioxide, which helps with eructation (belching). A slight excess of sodium bicarbonate remains, and it adds a small, direct acid-neutralising effect.
