Abstract
This invention is directed to a powder suitable for the preparation of a hematinic suspension which provides for controlled release of the iron contained in said powder. The powder to which this invention refers consists essentially of particles below a diameter of 50 microns. It is an iron adsorbate containing a specified amount of ferrous ions adsorbed on a specified cation exchange resin.
Claims3
In a powder suitable for the preparation of a palatable oral dosage form for a hematinic suspension for controlled release of the iron contained therein in the form of an iron adsorbate consisting essentially of 5-12% by weight of ferrous ions adsorbed on a nuclear sulfonic cation exchange resinous copolymer of styrene and divinylbenzene containing between 1% and 16% by weight of said divinylbenzene, the improvement being that essentially all iron adsorbate particles have a diameter below 50 microns.
