Active components
Mannuronate (mannuronic acid) and guluronate (guluronic acid).
Usage
Soluble at a basic pH, the alginates form a light gel when they come into contact with stomach acid, which allows them to float to the surface of the stomach content at the gastroesophageal junction. In the case of reflux, only the gel and not the acidic liquid will reflux into the oesophagus. Moreover, it will line the oesophagus, thus preventing the stomach fluids from coming into contact with the mucous membrane. In addition, its viscosity and coherence form a physical barrier that prevents reflux and therefore reduces the number of regurgitations. Finally, the alginate reduces gastric acidity.
