  • Translucent antacid suspension containing co-dried dihydroxy aluminum sodium carbonate
    Patent number: 6110505
    Abstract: The invention provides an essentially translucent liquid antacid composition with dihydroxyaluminum sodium carbonate (DASC) as the active ingredient. The DASC is prepared by co-drying DASC with a polyol, and the resulting co-dried DASC/polyol is mixed with water to form the liquid composition. The antacid composition preferably contains additional polyol to further improve the translucency of the liquid composition.

  • Translucent antacid suspension
    Patent number: 5874112
    Abstract: An essentially translucent antacid composition is formed by an aqueous colloidal aluminum hydroxide gel wherein the average particle size of the aluminum hydroxide is less than about 0.5 microns, preferably less than about 0.1 microns, and more preferably less than about 0.01 microns. The suspension is further preferably mixed with a polyol, such as sorbitol or maltitol, to enhance the translucency. The weight ratio of polyol to aluminum hydroxide gel (USP) ranges from about 0.5:1.0 to about 4.0:1.0.
