Aluminum Hydroxide, Magnesium Hydroxide are antacids used together to relieve heartburn, acid indigestion, and upset stomach. They may be used to treat these symptoms in patients with peptic ulcer, gastritis, esophagitis, hiatal hernia, or too much acid in the stomach (gastric hyperacidity).
Aluminum hydroxide has plenty of applications; some people believe that these uses are really endless. Just to illustrate the broadness of the uses, we can say that aluminum hydroxide is used as mordant in dyes, purifier for water, ingredient for cosmetics, and even in as an element for processes in photography. There are also applications of minor character in ceramics and construction. But the most important field where aluminum hydroxide is applied is medicine.
