摘 要:[Objectives]To prepare plumbagin nanomicelle(PLB-N)in-situ gel,and optimize the formulation and process.[Methods]PLB-N was prepared by self-assembly method,and the optimal formulation of PLB-N in-situ gel was determined by orthogonal experiment design and single factor method.[Results]The optimal preparation process for PLB-N was a drug to lipid ratio of 1:3,a Tween 80 content of 5%,an ethanol content of 7.5%of the hydration medium,a magnetic stirring speed of 2200 rpm,a stirring time of 30 min,and an ultrasound time of 10 min.The optimal formulation of PLB-N in-situ gel was 22%of poloxamer 407,6%of poloxamer 188,and 1:1 of PLB-N to water.The encapsulation efficiency of PLB-N prepared with the optimal formula was(95.8%±0.4%),and the average particle size was(75.19±1.14)nm,and the Zeta potential was(-20.73±1.19)mv.[Conclusions]PLB-N in-situ gel had stable and reliable preparation process,uniform content,and broad application prospects.
