摘要
The present invention provides a process for the preparation of an antacid material based upon magnesium aluminium hydroxide, wherein magnesium hydroxide and/or magnesium oxide is reacted in an atomic ratio of magnesium to aluminium of 1:1 to 3:1 with an aqueous solution of aluminium sulphate until the pH of the reaction mixture is from 4.0 to 8.0, whereafter water-soluble components are removed from the mixture in known manner and this is isolated and, if desired, dried. The present invention also provides pharmaceutical compositions containing an antacid material prepared by this process, in admixture with a conventional pharmaceutical adjuvant. Furthermore, the present invention provides a method of combating hyperacidity and gastrointestinal diseases, which comprises administering an antacid material prepared by the above process.
