Objective: To find the optimized prescription to reduce the times and the cost of the experiment. Methods: The Uniform Design Method in math was used in the prescription selection of the preparation. Results: The entrapment of the liposomal 5 FU that were prepared according to the Uniform Design Method was 39.21% and the stability, the particle size,and the appearance of the liposomal 5 FU were all perfect,and the change of the hydrolysate and peroxide values were all very small. The stability of the lipo...
