Abstract: A new modus and a new regimen of administration of divalent iron relates to therapy of hyposideremia, at the same time reducing toxic side effects. New formulations containing divalent iron compounds are adapted to release iron for intrabuccal absorption, preferably by sublingual absorption, that achieve these objects.
Abstract: Process for the preparation of trivalent iron complexes with mono-, di- and polysaccharide sugars, consisting of the activation of the sugar by oxidation with nascent bromine generated in situ by reaction between an alkaline or alkaline earth bromine and an alkaline hypochlorite, the complexation of the activated sugar in solution with a ferric salt dissolved in an aqueous solution, the purification of the resulting solution through ultrafiltration and finally the stabilization of the trivalent iron-sugar complex by heating at a temperature between 60° C. and 100° C. for a period between 1 and 4 hours at a pH between 9.0 and 11.0.

Abstract: New low molecular weight complexes between iron and maltobionic acid that can be administered parenterally, preferably intramuscularly or subcutaneously, in the treatment of anemic states, caused by iron deficiencies, and new pharmaceutical compositions adapted for this use. In particular, the invention provides a new complex between preferably trivalent iron and maltobionic acid that is characterized by a molecular weight Mw between 10,000 and 30,000 Da, by a polydispersity of 1.0-1.8 and by an iron content between 25% and 40% by weight.
