聚乳酸-羟基乙酸共聚物(PLGA)是用于药物控释系统的最成功的聚合物生物材料。PLGA有几种不同的化学和物理性质,影响药物从PLGA递送装置的释放行为。这些性质必须在药物释放装置的配方中加以考虑和优化。数学建模是一个有用的工具,用于识别,表征和预测控制释放的机制。聚(乳酸-羟基乙酸共聚物)的优点和局限性的控制释放进行了审查,其次是审查目前的控制释放技术,利用PLGA的方法。还将讨论应用于PLGA基装置的控释速率的数学建模,以提供对该聚合物系统可实现的控制的最新理解的完整图片,以及限制。
Poly-lactic-co-glycolic acid (PLGA) has been the most successful polymeric biomaterial for use in controlled drug delivery systems. There are several different chemical and physical properties of PLGA that impact the release behavior of drugs from PLGA delivery devices. These properties must be considered and optimized in drug release device formulation. Mathematical modeling is a useful tool for identifying, characterizing, and predicting the mechanisms of controlled release. The advantages and limitations of poly (lactic-co-glycolic acid) for controlled release are reviewed, followed by a review of current approaches in controlled release technology that utilize PLGA. Mathematical modeling applied towards controlled release rates from PLGA-based devices will also be discussed to provide a complete picture of state of the art understanding of the control achievable with this polymeric system, as well as the limitations.
