ABSTRACT:
A method for separating and purifying the active hematinic species (AHS) present in iron-saccharidic compositions, including AHS such as sodium ferric gluconate complex, ferric hydroxide-sucrose complex and ferric saccharate complex and others of similar form and function. The method separates the AHS from one or more excipients and, preferably, lyophilizes the separated AHS. Separation of the AHS permits its analytical quantification, further concentration, purification and/or lyophilization as well as preparation of new and useful products and pharmaceutical compositions.
