pharmachologic effect

Antacid preparation. When ingested, Gaviscon Double Action reacts quickly with the acidic contents of the stomach. In this case, the alginate gel is formed, which has an almost neutral pH value. The gel forms a protective barrier on the surface of the stomach contents, preventing the occurrence of gastroesophageal reflux. In the case of regurgitation, the gel is more likely to enter the esophagus, where it reduces the irritation of the mucous membrane.
Calcium carbonate quickly neutralizes the hydrochloric acid of gastric juice, alleviating the feeling of heartburn and indigestion. This effect is enhanced by the presence of sodium bicarbonate in the formulation of the sodium, which also has a neutralizing effect. The total acid neutralizing activity of the drug in the minimum dose (2 tab.) Is approximately 10 mEq.
