nifedipine dispersible tablets
; central composite design-response surface methodology; prescription screening; dispersible uniformity; cumulative dissolutionObjective: To optimize the formulation of dispersible tablets using nifedipine as a model drug by central composite design-response surface methodology. Methods: Solid dispersion method was applied to improve the solubility of nifedipine. The proportion of PEG4000, PVPP and CCNa were studied based on the theory of central composite deign using dispersible uniformity and 10min cumulative dissolution as evaluation indexes. The correlation between evaluation indexes and formulation were simulated using multi-linear equation and second-order polynomial equation. The possible optimal formulation was predicted by response surface method. Results: Second-order fitting models were superior to first-order models with better regression coefficients and higher reliability. The optimized formulation was NFP: PEG4000=1:4 in solid dispersion; the dosage of PVPP and CCNa accounted for 15% and 8% in formulation, respectively. Conclusion: The established model based on the theory of central composite design is suitable for the optimization of nifedipine dispersible tablets.
