  • PROCESS FOR THE PREPARATION OF IRON (III) CARBOXYMALTOSE COMPLEX
    Publication number: 20120214986
    Abstract: The present invention relates to novel processes for the preparation of iron (III) carboxymaltose complex. Thus, for example, a mixture of one or more maltodextrins, ferric hydroxide and water is heated, the resulting iron maltodextrin complex is oxidized using an aqueous sodium hypochlorite solution, followed by maintaining at 25° C. to 125° C. to produce iron (III) carboxymaltose complex.
