Objective: To optimize film coating process of Xinqingning tablet. Method: Orthogonal test was used with the concentration of coating solution
the spray amount of coating solution
inlet air temperature and rotation of coating pan as factors
technology parameters of coating process were optimized by composite score method. Result: Optimum coating process parameters were:the concentration of coating solution 0.14 g·mL-1
the spray amount of coating solution 5.05-5.15 g·min-1
inlet air temperature 80 ℃
rotation of coating pan 6-8 r·min-1. Conclusion: This optimized technology was stable and feasible
