本文介绍近年来采用物理混合法、尤其是放射线方法开发和应用药物-高分子复合物的研究成果。这种复合物一般称为给药系统(DDS)。其目的为控制药物释放和使药物选择性地转运到靶器。 DDS的给药形式有:将DDS给予局部患处(局部疗法);在吸收良好的部位给药,使释放的药物随血液循环作用于患部(称为大 This article describes the recent years the use of physical mixing method, especially the development and application of radiation-drug-polymer composite research results. This compound is commonly referred to as the Dosing System (DDS). Its purpose is to control the release of the drug and the selective transport of the drug to the target. DDS is administered in the form of DDS given to the affected area (topical therapy), administered in a well-absorbed area so that the released drug acts on the affected area with blood circulation
