摘要
聚乳酸-羟基乙酸共聚物(PLGA)包裹药物制成微球制剂是近年来药物输送体系的研究热点,但是PLGA包囊药物尤其是蛋白多肽类变性失活问题是研究的难点.改进生产工艺特别是使用添加剂可提高微球中包载药物的稳定性.综述了PLGA微球制备及释放过程中不同添加剂的作用特别是稳定蛋白药物的作用.
Microspheres made of poly-lactic-co-glycolic acid (PLGA) have been frequently proposed as drug delivery systems. A very significant challenge in the development of controlled PLGA releasing systems is the instability of drugs especially therapeutic peptides and proteins. Additional approaches, particularly the use of additives, are needed to optimize PLGA delivery of drugs. This article reviews the effects of additives, especially the effects of stabilizing protein during the preparation of PLGA mierosphere and the sustained drug releasing processes.
