Objective: To optimize matrix formulation of Fumikang gels. Method: With viscosity (32℃)
thixotropy (32℃) and stability as dependent variables
amounts of sodium carboxymethyl cellulosef (CMC-Na)
glycerine and polysorbate 80 (tween-80) as independent variables
single factor test was adopted to screen ranges of each independent variable
matrix formulation of Fumikang gels was optimized by central composite design-response surface methodology. Result: Optimal formulaiton was as following:CMC-Na 3.5 g
glycerine 8.0 g
tween-80 5.0 g;these measured values of stability
thixotropy and viscosity were 19.5 point
7 686.9 Pa· s-1· mL-1 and 4 325.9 mPa· s;these predicted values were 20 point
7 815.843 Pa· s-1· mL-1 and 4 442.731 mPa· s;absolute values of deviations between the measured value and the predicted value were 2.50%
1.65% and 2.63%
respectively. Conclusion: These prepared Fumikang gels had appropriate viscosity
good stability and thixotropy
this study could provide a reference for clinical practice of this preparation.
