Iontophoresis device using a rate-controlling membrane |
摘要 |
<p>An iontophoresis device comprising a drug reservoir containing the drug in ionic form and in communication with the skin, a skin permeation enhancing agent contained in the reservoir or in a second reservoir also in communication with the skin, an electrode in contact with the drug, another electrode in contact with the skin, a D.C. power source connected to the electrodes and an electrically sensitive membrane interposed between the reservoir and the skin that is impermeable to drug in the absence of a voltage difference between the electrodes and permeable to the drug in the presence of a voltage difference. The skin permeation enhancing agent eliminates the skin as a rate-controlling element, thus making the rate of drug administration dependent upon the membrane permeability, which in turn is controlled electrically.</p> |
