Embodiments of the invention provide patches for the transdermal delivery of iron-containing compositions to an individual suffering from an iron deficiency. Many embodiments provide an iontophoretic patch for the transdermal delivery of a therapeutically effective amount of iron. The patch comprises an electrode and a reservoir containing a composition comprising ionic iron for the delivery of the therapeutically effective amount of iron. Various embodiments provide methods of using embodiments of the iontophoretic patch for delivering a therapeutically effective amount of iron to an individual suffering from one more forms of iron deficiency including iron deficiency anemia. Such methods can be used for treating and/or preventing the iron deficiency. The amount of delivered iron can be adjusted depending upon various treatment parameters such as patient weight and type and amount of iron deficiency.

1. An iontophoretic patch for the transdermal delivery of a therapeutically effective amount of iron, the patch comprising an electrode and a reservoir containing a composition comprising an effective amount of an ionic iron in a chelated iron complex comprising ferric pyrophosphate for the delivery
1. An iontophoretic patch for the transdermal delivery of a therapeutically effective amount of iron, the patch comprising an electrode and a reservoir containing a composition comprising an effective amount of an ionic iron in a chelated iron complex comprising ferric pyrophosphate for the delivery of the therapeutically effective amount of iron, wherein the patch does not comprise a polyolefin material in contact with the composition, and wherein the composition does not include heme iron or heme iron polypeptide, and the reservoir contains an amount of the composition to continuously deliver a therapeutically effective amount of iron for a period of at least 3 days. 2. The patch of claim 1, wherein the reservoir comprises a layer of the patch. 3. The patch of claim 1, wherein the reservoir comprises a compartment. 4. The patch of claim 1, wherein the reservoir comprises substantially the entire patch. 5. The patch of claim 1, wherein the composition further comprises at least one agent selected from the group consisting of: a vitamin supplement, erythropoietin, and an erythropoietin stimulating agent. 6. The patch of claim 1, wherein the composition further comprises at least one transdermal permeabilizing agent. 7. The patch of claim 6, wherein the at least one transdermal permeabilizing agent comprises a cyclodextrin. 8. The patch of claim 1, wherein the composition comprises an amount of elemental iron in a range from about 10 mg to about 50 mg. 9. The patch of claim 1, wherein the composition comprises an amount of elemental iron in a range from about 1 mg to about 100 mg. 10. The patch of claim 1, wherein the composition comprises an amount of elemental iron in a range from about 1 mg to about 75 mg. 11. The patch of claim 1, wherein the composition comprises an amount of elemental iron in a range from about 1 mg to about 50 mg. 12. The patch of claim 1 wherein the composition comprises an amount of elemental iron in a range from about 1 mg to about 10 mg. 13. The patch of claim 1, wherein the patch includes at least one needle configured to penetrate a selected depth into a stratum layer of skin to enhance delivery of the composition while minimizing perceptible pain from the penetration. 14. The patch of claim 13, wherein the at least one needle includes an array of needles. 15. The patch of claim 14, wherein the at least one needle has a length in the range of about 100 to about 150 μm. 16. The patch of claim 1, further comprising a rate controlling member positioned between the reservoir and a tissue contacting side of the patch, the rate controlling member configured to control a rate at which iron migrates from the reservoir to the tissue contacting side. 17. An iontophoretic system for the transdermal delivery of a therapeutically effective amount of iron, the system comprising the patch of claim 1; and a second patch, the second patch having a skin contacting layer comprising a plurality of needles, the plurality of needles arranged in an arrayed pattern and having a length of from about 10 μm to about 150 μm. 18. The system of claim 17, wherein the needles have a length in the range of about 100 to about 150 μm. 19. The system of claim 17, wherein the arrayed pattern of needles is configured to create channels in the stratum corneum with an application force to the second patch of no more than about 10 newtons. 20. An iontophoretic patch for the transdermal delivery of a therapeutically effective amount of iron, the patch comprising an electrode and a reservoir containing a composition comprising an effective amount of an ionic iron in a chelated iron complex for the delivery of the therapeutically effective amount of iron, wherein the patch does not comprise a polyolefin material in contact with the composition, and wherein the composition does not include heme iron or heme iron polypeptide, and the reservoir contains an amount of the composition to continuously deliver a therapeutically effective amount of iron for a period of at least 3 days, and wherein the chelated iron complex comprises ionic iron selected from the group consisting of ferric gluconate, ferric ammonium sulfate, ferric ammonium oxalate, ferric potassium oxalate, ferric sodium oxalate, ferric trisglycinate, ferric bisglycinate, ferric aspartate, ferric citrate, ferric ammonium citrate, ferric choline citrate, ferric manganese citrate, ferric quinine citrate and ferric sodium citrate.
