Algisum is indicated for the treatment of symptoms resulting from the reflux of acid, bile and pepsin into the esophagus such as acid regurgitation, heartburn, indigestion for instance, after gastric surgery, as a result of hiatus hernia, during pregnancy, accompanying reflux esophagitis, including symptoms of laryngopharyngeal reflux such as hoarseness and other voice disorders, sore throats and cough. Algisum can also be used to treat the symptoms of gastroesophageal reflux during concomitant treatment with or following the withdrawal of acid suppressing therapy.


This is the combination of Sodium Alginate and Potassium Bicarbonate. Sodium Alginate is a naturally occurring substance. It 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 formed by Sodium Alginate and they allow the gel to float like a raft on top of the stomach contents. The raft prevents acid in the stomach from flowing back into the esophagus. This relieves the symptoms of reflux such as heartburn. The mode of action of this is physical and does not depend on absorption into the systemic circulation. The raft lasts for up to 4 hours on top of the stomach contents and is then broken down in the digestive system and excreted in the feces.
