Water-soluble iron-carbohydrate derivative complex obtainable from an aqueous iron(III) salt solution and an aqueous solution of the product of the oxidation and subsequent derivatization of one or more maltodextrins with an aqueous hypochlorite solution at alkaline pH, wherein, in the case of use of a maltodextrin whose dextrose equivalent is from 5 to 20 and in the case of use of a mixture of a plurality of maltodextrins, the dextrose equivalent of the mixture is from 5 to 20 and the dextrose equivalent of each individual maltodextrin involved in the mixture is from 2 to 40, and the subsequent derivatization is effected with a suitable reagent, processes for preparing them and medicaments for treatment and prophylaxis of iron deficiency conditions.

L'invention concerne un complexe de fer et de dérivés d'hydrates de carbone, pouvant être obtenu à partir d'une solution saline de fer(III) aqueuse et d'une solution aqueuse du produit de l'oxydation, et par dérivatisation consécutive d'une ou plusieurs maltodextrines avec une solution d'hypochlorite aqueuse à un pH alcalin. En cas d'utilisation d'une maltodextrine, l'équivalent dextrose de celle-ci se situe entre 5 et 20, et en cas d'utilisation d'un mélange de plusieurs maltodextrines, l'équivalent dextrose du mélange se situe entre 5 et 20 et l'équivalent dextrose de chaque maltodextrine contenue dans le mélange se situe entre 2 et 40, la dérivatisation consécutive étant réalisée avec un réactif adéquat. L'invention concerne également des procédés de fabrication de ces complexes et des médicaments de prophylaxie et de traitement d'états de carences en fer.
