Abstract: Objective To optimize the preparation and study in vitro releasing of SRL-NLC dispersion. Methods Central composite design-response surface methodology was used to optimize dispersion formulation,then in vitro releasing in 0.4% SDS(sodium lauryl sulfate) solution was explored by normal phase dialysis bag method. Results The optimal dispersion had PS(particle size):82.54nm,PI(polydisperity index):0.207, Zeta potential: -18.0 mv,DL (drug-loading): 1.829%, and EE(entrapment efficiency): 91.3%; SRL-NLC dispersion had a characterization of 60.1% accumulated releasing in 0.4%SDS solution. Conclusion The optimal formulation had good feasibility and reproducibility, in vitro releasing curve showed SRL-NLC dispersion had a characterization of 60.1% accumulated releasing in 0.4% SDS solution.
