PCT No. PCT/HU87/00026 Sec. 371 Date Mar. 28, 1988 Sec. 102(e) Date Mar. 28, 1988 PCT Filed Jun. 24, 1987 PCT Pub. No. WO88/00051 PCT Pub. Date Jan. 14, 1988.The invention relates to the production of a new pharmaceutical preparation of high acid-binding capacity, of delayed effect, of increased bioavailability for neutralization of gastric acid and eventually to other pharmaceutical preparations acting in the gastrointestinal tract, first of all of laxative effect by mixing 100 parts by mass of a powdered basic magnesium compound or the powdered mixture of basic magnesium compounds and basic aluminum compounds with 2-2500 parts of a dry or water-swollen organic acid of polymeric character and therapeutically acceptable, e.g. cellulose-glycolic acid, starch-glycolic acid or polymer acrylic and/or methacrylic acid, letting this powdered mixture to stand for 1-24 hours at the temperature of 20 DEG -80 DEG C. after addition of 50-500 parts by mass of water and forming tablets or other pharmaceutical preparations, optionally after addition of 5-60 parts by mass of smoothing agents and/or other pharmaceutical excipients, or transforming the mixture containing the basic active ingredients and the polymeric organic acid in liquid suspension by adding water and optionally excipients.
