Gaviscon Double Action Oral Suspension is a medication designed to provide relief from heartburn and indigestion. It combines three active ingredients: Sodium Alginate, Sodium Bicarbonate, and Calcium Carbonate. These ingredients work together to form a protective barrier on top of the stomach contents, preventing acid from rising into the esophagus and relieving discomfort. Sodium Alginate helps form the gel-like barrier, Sodium Bicarbonate neutralizes stomach acid, and Calcium Carbonate provides additional antacid action. The suspension is available in a 10ml sachet, offering a convenient, single-dose solution for quick relief from acid reflux symptoms.
