Abstract: Objective To optimize the prescription of flaxseed lignans sustained release tables by central composite design-response surface methodology.MethodsWith HPMC, EC and starch dosage as factors, and flaxseed lignans in 2, 6 and 12 h of cumulative release as evaluation indexes, central composite design-response surface optimization method was used to conduct prescription optimization experiments, and optimized prescription analysis was carried out.Results The optimal prescription of flaxseed lignans sustained release tables was as following: HPMC dosage was 43%; EC was 26%; starch content was 17%. Optimized index forecast values were very close to the observed values. In vitro release test of three selected optimal formulations indicated that there existed high approximation between the observed and estimated values.Conclusion It shows that the established model is suitable for flaxseed lignans sustained release tables, which can be used in the optimization of the prescription of flaxseed lignans sustained release tables.
