Objective To optimize the prescription ofBaichanting Tablets by the central composite design-response surface methodology.Methods The doses of MCC, cCMC-Na, SiO2, and magnesium stearate were set as investigation factors; disintegration time and moisture rate were set as indexes. Linear equation quadratic polynomial described mathematic relationship of disintegration time and moisture rate with other four influence factors. Response surface was described according to the optimal mathematic models; the optimal prescription was chosen; predictive analysis was conducted.ResultsThe relationship of disintegration time and moisture rate with other four influence factors could not be described by linear equation. When quadratic polynomial matching was used, correlation coefficients were 0.837 9 and 0.923 1, with relatively high reliability. Optimal prescription contained 30.6%MCC, 10%cCMC-Na, 0.30%SiO2, and 0.10% magnesium stearate. The theoretical value and predicted value deviations of the disintegration time limit and moisture absorption rate were within 5%.Conclusion The predictability of the established model is good. Application of central composite design-response surface methodology can precisely optimize the prescription ofBaichanting Tablets.
