Sodium Alginate + Magnesium Alginate


Gastric reflux, heartburn, flatulence associated with gastric reflux, heartburn of pregnancy, all cases of
epigastric and retrosternal distress where the underlying cause is gastric reflux.


On ingestion the product reacts rapidly with gastric acid to form a raft of alginic acid gel having a near neutral pH and which floats on the stomach contents, quickly and effectively impeding gastrooesophageal reflux, for up to 4 hours. In severe cases the raft itself may be refluxed into the esophagus, in preference to the stomach contents, and exert a demulcent effect.
