What is alginic acid, aluminum hydroxide, and magnesium carbonate?
Alginic acid is a natural carbohydrate that comes from algae in seaweed (kelp) and is used in many processed foods. It helps this medication create a foam barrier to coat the stomach.
Aluminum and magnesium are minerals that occur naturally and are used as antacids.
The combination of alginic acid, aluminum hydroxide, and magnesium carbonate is used to treat symptoms of stomach ulcers, gastroesophageal reflux disease (GERD), and other conditions caused by excess stomach acid. This medicine is also used to treat heartburn, upset stomach, sour stomach, or acid indigestion.
