    • The present invention relates to a solid oral pharmaceutical preparation with protracted release of the active ingredient consisting of discrete solid granules containing the active ingredient soluble in the stomach and auxiliary agents and of an equally solid external phase surrounding the said granules, whereby the granules forming the internal phase consist of granules prepared from a powder mixture which contains as active ingredient, or in addition to it a non-toxic metal compound, being capable of binding an acid, and being insoluble or but slightly soluble in neutral aqueous medium--particularly bismuth, aluminium or magnesium compound--and auxiliary materials prepared with an aqueous emulsion containing a hydrophobic component and hydrophylic emulsifiers, and the external phase contains a solid, dry, amphoteric gel forming substance in an amount of 1-50 percent w/w related to the total weight of the preparation in admixture with auxiliary agents.The preparation is produced by the wetting of the powder mixture containing the basic metal compound, auxiliary material and in given case additional active ingredient with the aqueous emulsion of the hydrophobic component prepared by applying the hydrophylic emulsifiers then by granulation and admixing the dried granules with the amphoteric gel forming substance, and pressing it into tablets, or filling into capsules.
