药品的治疗效果常常与给药方式密切相关。而口服、肌肉注射、静脉注射等给药方式因有其局限性,使得透皮控释给药方式获得了广泛应用。这种给药方式是将药物载于贴片上,使药物透过皮肤进入人体并直接作用于患部。常见的有均匀涂有药物的胶布,或是中心附有药物的贴片,还有一种是中间有环形凸台的贴片。但它们均有一个共同的缺陷,那就是只适用于单一组分或单一用途的药物。 The therapeutic effect of the drug is often closely related to the mode of administration. Oral, intramuscular, intravenous and other drug delivery methods due to its limitations, making transdermal controlled release drug delivery has been widely used. This method of administration is to place the drug on the patch, allowing the drug to penetrate the skin into the body and act directly on the affected area. Common with a uniform coated with adhesive tape, or the center with the drug patch, there is a ring with a central boss patch. But they have a common flaw, that is, only applies to a single component or single-purpose drugs.
