    摘要: To avoid a reduction of the conductivity in iontophoresis due to the electrical decomposition and the changes in chemical properties of the electrodes themselves, covering by an electrical insulator, and to prevent a drop in the transport rate due to ions freed from the electrode. Provision is made of an electrode structure provided integrally with a reversible electrode and an auxiliary electrode for regeneration of the same and a regeneration current conducting means for conducting a current for regeneration of the reversible electrode when the therapeutic current is off, or the invention is comprised of a reversible electrode and an ion exchange membrane difficult for ions freed from that electrode to penetrate.

    摘要: An interface is formed by incorporating (1) a mixture comprising a water-soluble protein and a drug into a matrix, or preferably (2) a mixture comprising a water-soluble protein and a drug to a porous matrix coated with a cationic surfactant or other ionic surfactant. The coating amount of the ionic surfactant is about 0.1 to 50 .mu.g, and the content of the water-soluble protein is about 0.1 to 1,500 .mu.g, each per 1 cm.sup.2 of the matrix. The water-soluble protein includes an albumin and the drug includes a physiologically active peptide or protein, for example. The use of the stabilized interface inhibits decrease of the drug retaining amount, and insures an effective transdermal drug delivery with a high repeatability and accuracy.

    摘要: A calcitonin, its derivative or a salt thereof is transdermally delivered by iontophoresis in which a substantially constant voltage in the range of 3 to 20 V is applied at an electric current of 0.05 to 0.5 mA/cm.sup.2. In this process, the calcitonin can be delivered transdermally with a higher absorptivity by applying a higher voltage for a short period (at a voltage of about 6 to 14 V for about 5 to 15 minutes) in the initial stage of the voltage application, and then applying a lower voltage for a long period (at a voltage of about 3 to 9 V for about 30 to 40 minutes).
