Objective: To optimize preparation process of Huoxue cataplasm. Method: Taking composite score of adhesion
appearance uniformity
film residue
skin compliance
spreadability and others as index
based on single factor tests
central composite design-response surface methodology was used to optimize preparation process with amounts of sodium polyacrylate-700
glycerin
aluminium glycinate and povidone K-90 as factors. Result: Optimum substrate composition was sodium polyacrylate-700/polyvinyl/glycerin/aluminium glycinate/povidone K-90/aerosil/water/ointment was 4.7:0.5:29.2:0.5:3:4:22.4:12.9.Cataplasm was coated easily with smooth cream surface
consistent color
good skin followability and no leakage. Conclusion: This preparation process is rational and suitable for production of Huoxue cataplasm.
