Abstract:
Objective To establish the preparation method of Xiao' er Jiere hollow type suppository and determination method of the dissolubility.Methods Xiao' er Jiere hollow type suppository and ordinary suppository were prepared.With bacalin and chlorogenic acid as the standards,the in-vitro dissolution test and HPLC method were applied to determine the accumulated dissolution rate of bacalin and chlorogenic acid in two different types of suppository.Results The linearity of bacalin was in the range of 0.040 ? g～ 0.320 ? g(r=0.999 7)and that of chlorogenic acid was in the range of 0.064～ 0.512 ? g(r=0.999 8).The accumulated dissolution rate of the hollow type suppository was over 97 % in 30min.Conclusion Drug release rate of hollow type suppository is higher than the ordinary suppository.The method is stable and accurate.
