FLUIDIZED MAGALDRATE SUSPENSION

An aqueous antacid composition of magaldrate gel and a process for preparing same are described by the invention. The composition is prepared from and contains precipitated and undried magaldrate gel and a fluidizing of a first and second fluidizer. On fluidizer is provided by an aluminum hydroxide gel having colloidal properties and the second by a pharmaceutically acceptable citrate ion source including citric acid. The process and composition are characterized in providing a fluid, resuspendible, pharmaceutically elegant suspension possessing high antacid capacity and stability at even elevated magaldrate concentrations in addition to the ability to fluidize stiff, paste-like magaldrate gel cakes.
