| Abstract: | OBJECTIVE To study the dissolution rate and in vitro releasing characteristics of lovastatin capsules （tablets）. METHODS The experiment was conducted according to the first method （the rateting basket method） dissolution rate in China Pharmacopeia 2005, second section, appendix XC. Phosphate buffer solution-npropanol （2 ： 1 ） 900mL was used as the mediums for dissolution, and the determination method was HPLC. RESULTS The calibration curve of lovastatin was linear within a range of 1.998μg·mL^-1 29.820μg· mL^-1, r = 0. 9998, and the range of the recovery was 99.5 %- 100.0 %, RSD = 0.4 % --0.8 %. CONCLUSION The method is simple, accurate and sensitive. It shows a good dissolution rate. |
