An iontophoresis device capable of administering of first drug ions resulting from dissociation in conductive form through a skin contact member having multiple needlelike items for skin puncturing, wherein an element capable of selective permeation of first conductive ions is disposed between a drug retention part for retaining of drug ions and the skin of living body as recipient of the drug ions. Thus, there is provided an iontophoresis device that can not only enhance the rate of drug administration and the efficiency thereof but also realize administration of drugs of high molecular weight, such as proteins and peptides.
L~invention concerne un appareil d'iontophorèse capable d'administrer les premiers ions d~un médicament résultant d~une dissociation sous forme conductrice à travers un membre de contact avec la peau possédant plusieurs éléments semblables à des aiguilles pour poncturer la peau. Cet appareil comporte un élément capable de faire pénétrer sélectivement de premiers ions conducteurs et qui est placé entre une pièce de rétention du médicament contenant les ions du médicament et la peau d~un corps vivant destinataire des ions du médicament. Donc, il s~agit d~un appareil d'iontophorèse qui peut non seulement intensifier le taux d'administration et l~efficacité d~un médicament, mais aussi permettre l'administration de médicaments de haut poids moléculaire, tel que des protéines et des peptides.
