Ranigast S O S is used to reduce gastroesophageal acid reflux symptoms such as heartburn and abdominal pain. They help control the increased acidity of the stomach, preventing burning, abdominal pain and indigestion. Effective regardless of the root cause of the problem. In addition, it can also be used as an adjuvant in gastritis patients. When it gets into the acidic environment of the stomach, sodium alginate fibers very quickly cause gelation. The alginate gel coats and protects the stomach lining. The combination of bicarbonate and carbonate neutralizes the acidic environment of the stomach. The alginate gel binds the bubbles of carbon dioxide formed during the reaction of hydrochloric acid. As a result, the number of reflux episodes decreases.
