Optimized Preparation and in Vitro Release Properties of Erinacines-PLGA Microspheres by Response Surface Methodology
摘要
Abstract
Purpose:To prepare slow-release erinacines microspheres with poly (lactic-co-glycolic acid) (PLGA) as carry using the emulsification solvent evaporation method and to investigate their release characteristics in vitro.Methods:The one-factor-at-a-time method was adopted to examine the factors affecting encapsulation efficiency,and their levels were optimized using response surface methodology.Results:The optimum preparation conditions were obtained as follows:erinacines to PLGA ratio,1∶1.64 (g/g);concentration of PLGA in dichloromethane,15%;and stirring speed,1 200 r/rain.The obtained microspheres were complete and smooth with an encapsulation efficiency of 99.66% and a cumulative release rate in vitro of 84.30% in 384 h.Conclusion:The emulsification solvent evaporation method has been successfully applied to prepare erinacines microspheres with high entrapment efficiency and good sustained release performance.关键词
