SUBSTANCE: invention refers to using mixed metal compounds for preparing a drug preparation for neutralisation of gastric acid or buffer action thereon, as well as for treatment of a condition or a disease related to high gastric levels of acid. The mixed metal compound is a compound of formula (I): M^II _1-aM^III _aO_bA^n- _c.zH₂O (I), wherein M^II and M^III mean a two-valence and three-valence metal respectively, A^n- means an n-valence anion, 0.2≤a≤0.4, 0.2≤b≤1.5, 2+a is equal to 2b+Σcn, Σcn<0.9a, and z is equal to 2 or less. According to the invention, the mixed metal compound is presented in the form of a granulated material, wherein a diametre of 50 wt % of the granules makes 106 to 1180 mcm with the material comprising 50 wt % of the mixed metal compound, 3 to 12 wt % of noncovalent water and no more than 47 wt % of an excipient on granulated material weight basis. The mixed metal compound in the form of the granulated material represents a compound of formula (I) or a compound of formula (III): M^II _1-xM^III _x(OH)₂A^n- _y·mH₂O (III) _; wherein M^II and M^III mean a two-valence and three-valence metal respectively, A^n- means an n-valence anion, x=Σyn, 0<x≤0.4, 0<y≤1, and 0≤m≤10.

EFFECT: invention provides the buffer action on gastric acid, causing no effect of rebound acid hypersecretion.
