To optimize the formulation of chansu-loaded solid lipid nanoparticles (Cs-SLN).Cs-SLN was prepared by cold homogenization technique. The effects of influence factors such as the weight of compritol 888 ATO, soybean lecithin and poloxamer 188, on mean diameter, entrapment efficiency, drug loading and overall desirability were investigated by using central composite design and response surface method. The data were imitated using multi-linear equation and second-order polynomial equation.The latter was prior to the former considering from multiple correlation coefficients. Under the optimal conditions, the mean diameter, entrapment efficiency, drug loading of the Cs-SLN were 71.5 nm, 92.45% and 5.26%.The optimized preparation technique for Cs-SLN is stable, feasible and high inclusion rate. It can be used for production of Cs-SLN. |
