Objective:To optimize the formulation and preparation condition of the Sufentanil solid lipid nanopartcles ( SUF-SLN ) . Methods: Four influence factors on the preparation condition of the SUF-SLN, including the dosage of Sufentanil ( A) , the concentration of surfactant ( B) , the content of solid lipid ( C) and the ratio of stearic acid and lecithin ( D) , were evaluated in the study. Three levels of each factor were selected, and the particle size was the major evaluation index. The screening experiment on the SUF-SLN preparation was performed based on the L9 ( 34 ) orthogonal experimental table. Results: The optimal formulation of SUF-SLN processed by comprehensive evaluation and statistical analysis was 100 μg Sufentanil dosage, 1. 5% F68 concentration, 1∶100 ratio of the drug and the lipid, and 5:1 ratio of stearic acid and lecithin.Conclusion:The SUF-SLN prepared by orthogonal experiment fulfills the criteria of the particle size, with optimal stability and appearance.
