(57) [Summary] (Modified) [Problem] A novel administration method of ionic drugs by iontophoresis. SOLUTION: An iontophoresis electrode section 1 is connected to a power source having the same polarity as the charged ions of the ionic drug, an electrode material 11, a conductive medium 12 arranged on the front surface of the electrode material, An ion exchange membrane 13 for selecting ions opposite to the charged ions of the ionic drug disposed on the front surface of the conductive medium, and an ion disposed on the front surface of the ion exchange membrane for selecting ions opposite to the charged ions of the ionic drug. An ion-exchange membrane 15 for selecting the same type of ions as the charged ions of the ionic drug disposed on the front surface of the ionic drug. An electrode material 21 having a polarity opposite to that of the electrode material, a conductive medium 22 disposed on the front surface of the electrode material, and ion exchange for selecting an ion opposite to a charged ion of the ionic drug disposed on the front surface of the conductive medium. And a film 23. |
