Magaldrate Gels and Powders

The antacid effectiveness of magaldrate can be used to treat peptic ulcers because it neutralizes gastric acid very quickly while buffering the pH even in presence of proteins and pepsin.

Magaldrate (Al5Mg10(OH)31(SO4)2,xH20) is a basic aluminum and magnesium compound possessing a layer structure connected by water and sulfate bridges. It is crystalline by nature. This unique crystal lattice structure results in its high reactivity. The antacid effectiveness of magaldrate can be used to treat peptic ulcers because it neutralizes gastric acid very quickly while buffering the pH (keeping it between 5 and 6) even in the presence of proteins and pepsin.

Magaldrate can also adsorb large quantities of bile acids, which prevents these acids from attacking the mucous membranes. Magaldrate is a highly reactive antacid designed for formulation of suspensions and tablets. The gel is available as 10% or 20% suspension. We offer a powder form as well.
