<p>An iontophoretic apparatus capable of transdermal introduction of drug ions (lidocaine ion) into living body interior through electric drive, comprising at least working electrode (124A) connected to the anode of power source (112); electrolytic solution retaining part (126A) disposed on the anterior surface of the working electrode (124A) and retaining an electrolytic solution; and cation exchange membrane (132A) disposed on the anterior surface of the electrolytic solution retaining part (126A), allowing passage of cations and having lidocaine ions linked thereto. The cations contained in the electrolytic solution are electrolytic substance ions that at current passage, ensure easy replacement with lidocaine ions but suppress re-replacement with lidocaine ions.</p> |
