    • Disclosed is a transdermal preparation containing a hydrophobic drug. As a method of continuing the high drug permeation, it is used an unique hydrophilic polymer system in which the drug can be contained in a high concentration under no water environment, a solubility of the hydrophobic drug is decreased as the water is introduced to the patch from the skin, so that the drug is maintained at the saturation concentration even though the drug content is decreased as the drug is permeated to the skin. During the application of the transdermal preparation to the skin, it is possible to continuously permeate the high amount of drug, to maintain the sufficient adhesion during the use and to minimize the skin side effect, because the hydrophilic polymer absorbs the water from the skin. The hydrophilic polymer system can serve the function thereof through the hydrophobic adhesive layer capable of preventing the water quickly absorbed from the skin from being evaporated to the outside of the patch.
    • 公开了含有疏水性药物的透皮制剂。 作为持续高药物渗透的方法,使用独特的亲水性聚合物体系,其中药物可以在无水环境下以高浓度包含,疏水性药物的溶解度随着水被引入贴剂而降低 即使在药物渗入皮肤时药物含量降低,药物也保持在饱和浓度。 在将透皮制剂施用于皮肤期间,由于亲水性聚合物从皮肤吸收水分,因此可以连续渗透大量的药物,以保持使用期间的足够的粘附性和最小化皮肤的副作用。 亲水性聚合物体系可以通过能够防止皮肤快速吸收的水蒸发到贴剂外部的疏水性粘合剂层来发挥功能。
