FIELD: medicine, pharmaceutics.
SUBSTANCE: invention refers to a method for preparing a microelement drug on the basis of an iron-dextrin complex. The method includes the following stages: mixed water-soluble iron (III) salt and one or more water-soluble salts containing other microelements, e.g., cobalt, copper, zinc, manganese and selenite, and low-molecular dextrin are neutralised before sedimentation of iron (III) hydroxide, alkalised to pH 9-11, heated up to complete resolution and neutralised with an acid. Then, membrane ultrafiltration procedure is used to purify the prepared colloidal iron-dextrin complex with microelement atoms deposited in a polymeric covalent lattice of iron (III) oxide, and to concentrate it.
EFFECT: method allows preparing high-effective high iron fixation polymicroelement drug ensuring the best effect in treating iron-deficient conditions and promoting immune system resistance.
