Sodium Alginate BP & Potassium Bicarbonate BP

Gerdex 500mg + 100mg 200 ml Suspension


Sodium Alginate reacts with the acid in the stomach to form a gel. Potassium Bicarbonate also reacts with the acid in the stomach to form bubbles of carbon dioxide. These bubbles are trapped by the gel and they allow the gel to float like a raft on top of the stomach contents. This pH-neutral raft prevents acid in the stomach from flowing back into the esophagus. This relieves the symptoms of reflux such as heartburn. In case of reflux esophagitis, Gerdex not only relieves the symptoms, but also protects the inflamed esophagus from the acid and allows it to heal. After three to four hours later this raft broken down in the digestive system and excreted in the faeces.
