Foam barriers in Gastroesophageal reflux disease

Foam barriers give a unique form of treatment for Gastroesophageal reflux disease. Foam barriers are tablets that contain an antacid and a foaming agent. As the tablet disintegrates and reaches the stomach, it turns into foam that floats on the top of the liquid contents of the stomach. The foam form a physical barrier to the reflux of liquid. At the same time, the antacid bound to the foam neutralizes acid that comes into contact with the foam. The tablets are best taken after meals and when lying down, both times when reflux is more likely to occur. Foam barriers are not often used as the first or only treatment for Gastroesophageal reflux disease. Rather, they are added to other drugs for Gastroesophageal reflux disease when the other drugs are not alone effective in relieving symptoms. There is only one foam barrier, which is a combination of aluminum hydroxide gel, magnesium trisilicate, and alginate.
