Gastrogel is an antacid medication that helps to combat acid in the stomach. This provides relief of symptoms caused by too much acid, such as indigestion and reflux. Gastrogel can neutralise acid that is already present in the stomach, but it doesn’t stop production of acid. Each of the ingredients in Gastrogel has a role to make the medication more tolerable:
Aluminium provides some extra protection (from gastric acid) to the cells lining the stomach.
Magnesium salts help prevent constipation, which may be caused by the aluminium.
Simethicone helps to prevent flatulence.
