  • Process for the selective elimination of inorganic phosphate from liquids by means of absorbent materials modified with polynuclear metal oxyhydroxides
    Patent number: 6103126
    Abstract: The present invention concerns the use of an adsorbent material modified with polynuclear metal oxyhydroxides for the selective elimination of inorganic phosphate from liquids, in particular from body fluids containing protein such as whole blood, plasma, liquid contents of the intestine as well as from dialysis fluid, as well as a process for the production of a pharmaceutical agent for oral application for the selective removal of inorganic phosphate in which an adsorbent material used according to the present invention, as such or pressed into powder form, is coated with a layer resistant to gastric acid or dispensed into an acid-resistant capsule. In order to selectively eliminate inorganic phosphate in an extracorporeal perfusion system, a body fluid such as whole blood or plasma is passed over one of the adsorbent materials.
    Type: Grant
