  • PROCEDURE FOR OBTAINING GADOTERATE MEGLUMINE FROM HIGH-PURITY TETRAXETAN (DOTA) AND ITS USE IN THE PREPARATION OF INJECTABLE GALENICAL FORMULATIONS
    Publication number: 20230248851
    Abstract: The present invention refers to a process for obtaining gadoterate meglumine from high purity tetraxetan (DOTA) which does not require the use of organic solvents and optimizes the conditions of the synthetic process. The tetraxetan from which the gadoterate meglumine is obtained by a synthetic process that includes a purification step in which at least one electrodialysis is performed. This procedure makes it possible to obtain a tetraxetan and a gadoterate meglumine with minimal amounts of impurities.

  • Process for the preparation of glucosamine salts
    Patent number: 7141556
    Abstract: This invention relates to a process for the preparation of glucosamine sulfate, glucosamine hydroiodide, glucosamine pyruvate, glucosamine phosphate or their mixtures with glucosamine hydrochloride, by electrodialysis. Starting from glucosamine hydrochloride, the exchange of the Cl? for an anion selected from the group consisting of SO4 ?2, I?, CH3COCOO? and PO4?3 takes place during the process. The electrodialyser comprises a cathode, anode, and means of separation composed of anion exchange membranes, cation exchange membranes, bipolar membranes or by other suitable means of separation. This invention also relates to a glycosamine sulphate containing chlorides obtainable by the process, and its therapeutic use.
