Abstract: Embodiments of the invention provide patches for the transdermal delivery of compositions to treat an individual suffering from hair loss. Many embodiments provide an iontophoretic patch for the transdermal delivery hair growth stimulating agents for the treatment of hair loss by stimulating the growth of new hair in areas of the scalp exhibiting hair loss. The patch comprises an electrode and a reservoir containing a composition comprising iron containing compound, such as a chelated iron compound for the delivery of the therapeutically effective amount of iron. The patch can be shaped to be placed and remain on the head. Various embodiments provide methods of using embodiments of the iontophoretic patch for delivering a hair growth stimulating agent such as a chelated iron compound, minoxidil and finasteride to the scalp and other areas exhibiting hair loss. Such methods can be used for re-growing hair, and/or preventing or slowing hair loss.

Abstract: Embodiments of the invention provide nanonized iron compositions for treatment of iron deficiency such as iron deficiency anemia. Many embodiments provide nanonized iron compositions which are sized to minimize adverse reaction such as immune response, adverse GI reaction and allergic reaction to iron compound included in the composition. The nanonized iron compositions can be used in a variety of drug delivery forms, including an oral dosage form, a transdermal patch, in an intravenous solution or in a dialysate for treatment of a patient with chronic kidney disease (CKD). Embodiments of the invention also provide methods of using the nanonized iron compositions for the treatment of iron deficiency in a patient in need thereof including patients with iron deficiency anemia and CKD.
