Problems solved by technology

In the traditional iontophoresis drug delivery method, usually electrically driven single-point electrodes or multiple drug delivery carriers with electrodes are used for drug delivery. skin burns
[0005] Therefore, the shortcomings of the traditional transdermal drug delivery scheme are: either the transdermal effect is not obvious, or it is easy to cause skin burns or cause skin damage such as pain

Abstract

The present invention provides an iontophoretic drug delivery device. The iontophoretic drug delivery device comprises a power supply for generating electricity required for permeating a medicament tobe permeated into a drug delivery region of a living body, an integrated dielectric layer used for covering the drug delivery region, and multiple electrodes, wherein the integrated dielectric layercomprises gel and the polar and free medicament to be permeated; the electrodes are electrically connected with the power supply and the integrated dielectric layer, so that the electricity generatedby the power supply can flow through the drug delivery region and at least part of the integrated dielectric layer; and at least part of the integrated dielectric layer has a preset resistance value.The iontophoretic drug delivery device provided by the invention not only can improve the transdermal efficiency, but also is not liable to cause skin injury.

Description

technical field [0001] The present application relates to a drug delivery device, in particular to a drug delivery device for iontophoresis. Background technique [0002] Transdermal drug delivery refers to drug delivery on the surface of the skin, so that the drug passes through the skin at a certain rate and enters the systemic circulation to produce systemic or local therapeutic effects. Because the transdermal drug delivery method has the advantages of not being affected by factors such as food in the digestive tract, and can continuously control the drug delivery rate, it has broad application prospects. [0003] In the process of transdermal administration, the stratum corneum of the skin has a barrier function, which makes it difficult to achieve the expected effect in terms of the transdermal rate and penetration amount of the current administration via the skin surface. The traditional solution to increase the transdermal rate and penetration rate is, for example, ...
