  • Patent number: 9283246
    Abstract: The present invention relates to pharmaceutical compositions containing carboxylated starch derivatives as well a their use as osmotics in particular for use in the treatment of chronic renal failure by dialysis.
    Type: Grant
    Filed: September 7, 2012
    Date of Patent: March 15, 2016
    Assignee: FRESENIUS MEDICAL CARE DEUTSCHLAND GMBH
    Inventors: Dominik Fenn, Thomas Schweitzer
  • Patent number: 9249345
    Abstract: The present invention relates to a novel dry concentrate for producing medical solutions, more particularly dialysis solutions, which comprises electrolyte components, buffer components and an osmotic agent, wherein the concentrate comprises magnesium carbonate instead of magnesium chloride. The use of magnesium carbonate as an electrolyte prevents the formation of slurries. By providing anhydrous glucose as an osmotic agent, and by optionally spatially separating this osmotic agent from other components, the occurrence of caking of the concentrate is additionally avoided. The occurrence of caking is further reduced by providing the buffer component sodium bicarbonate together with sodium chloride separate from all other components. The concentrate of the present invention is particularly suitable for use in multi-chamber container bag systems. The concentrate of the present invention exhibits good dissolution behavior and improved storage stability.
