Objective:To optimize matrix components of Huoxue Fengshi cataplasm by response surface method.Method: The amount of four matrix agents(sodium polyacrylate
polyvinyl alcohol
gelatin
glycerin) were optimized based on several appraisal indexes including quantity of remains on polyethylene membrane
repeatedly exposing paste
skin following nature
adhesion
peel strength and so on.Determinated optimize ratio by Box-Behnken central composite design.Result: Optimal proportion of matrix components was as following:sodium polyacrylate 6.68 g
polyvinyl alcohol 0.34 g
gelatinum 4.57 g
glycerol 1.01 g.Conclusion: Optimal matrix components of cataplasma was stable
comfortable
all indexes could meet requirements of external patching
