  • Patent number: 5651997
    Abstract: An antacid composition comprises, as antacid ingredients, a hydrotalcite and dihydroxyaluminium aminoacetate in such a ratio that the former/the latter equals 30/70 to 90/10 (by weight). The composition may further comprises a readily acting or rapid effecting antacid ingredient such as a magnesium hydroxide in an amount of 10 to 50% by weight. The antacid composition is improved in antacid properties and rapid effecting properties, and is useful as a pharmaceutical composition comprising the antacid composition, a carrier, an additive, an additional pharmaceutically active ingredient and so on. The total amount of the antacid ingredients in the pharmaceutical composition may be 10% by weight or more. The pharmaceutical composition may be formed into a fine granule or a granule with utilizing granulation, or into a tablet by compression-molding.
