    • 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.
    • 本发明的实施方案提供了将含铁组合物透皮递送给患有铁缺乏症的个体的补片。 许多实施方案提供用于透皮递送治疗有效量的铁的离子电渗贴剂。 贴剂包括电极和含有用于递送治疗有效量的铁的包含离子铁的组合物的储存器。 各种实施方案提供使用离子电渗贴剂的实施方案的方法,用于将治疗有效量的铁递送至患有一种更多形式的铁缺乏症(包括缺铁性贫血)的个体。 这些方法可用于治疗和/或预防缺铁。 输送铁的量可以根据各种治疗参数(如患者体重,铁缺乏的类型和量)进行调整。

    • Embodiments provide devices, systems and methods for the transdermal delivery of chelated compounds. One embodiment provides a method for the iontophoretic transdermal delivery of a chelated iron complex for the treatment of anemia. A first patch comprising an active electrode and a chelated iron complex is applied to the skin; a second patch containing an electrode is also applied. An electrical current is then delivered to the skin from the active electrode. The chelated complex is transported across the skin via electromotive force from the current, with the iron being substantially chromogenically unreactive with the skin during transport so that there is little or no tattooing of the skin due to the formation of insoluble oxidative products. The complex is then dissociated by phagocytosis or related process to release the iron where it may be bound by transferrin or ferritin and carried to other sites for storage or metabolic use.
    • 实施方案提供用于经皮递送螯合化合物的装置,系统和方法。 一个实施方案提供了用于治疗贫血的螯合铁络合物的离子电渗疗法透皮递送的方法。 将包含活性电极和螯合铁络合物的第一贴片施加到皮肤上; 还应用了包含电极的第二贴片。 然后从活性电极将电流输送到皮肤。 螯合络合物通过电流从电流传递穿过皮肤,铁在运输过程中与皮肤基本上不发生色素反应,因此由于不溶性氧化产物的形成,皮肤几乎或没有纹身。 然后通过吞噬作用或相关过程解离复合物以释放铁,其中它可被转铁蛋白或铁蛋白结合并携带到其它部位用于储存或代谢使用。
