Reflux suppressants.
Reflux is a process in which the stomach acid juices flow back up into the food pipe. Unlike the stomach, the lining of the food pipe is not resistant to acid so that when reflux occurs, it causes the pain and discomfort commonly known as heartburn. Gaviscon Advance forms a protective layer that floats on top of the stomach contents. This layer prevents reflux and keeps the stomach contents away from the lining of the food pipe to relieve the symptoms of the heartburn and acid indigestion.
