IONTOPHORESIS DEVICE

摘要

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.
