Objective:To prepare glycyrrhizae extracts coated sustained release pellets and study the drug release in vitro under different coating conditions.Methods:A single factor design experiment was applied to optimize the formulation of coated sustained release pellets.Results:A satisfactory 12 h sustained release curve can be obtained when the pellets is coated with Eudragit RS100 5%(w·w-1) and PEG6000 10%(w·w-1) under the optimized formulation.Conclusions:The increased weight and proportion of Eudragits RS100 and PEG6000 are the main factors which influence the drug release.
