头孢克洛%缓释胶囊%体外释放度
頭孢剋洛%緩釋膠囊%體外釋放度
두포극락%완석효낭%체외석방도
Cefaclor%Release capsule%Release rate in vitro
目的:建立头孢克洛缓释胶囊体外释放度的测定方法。方法采用溶出度第一法,以水900mL为溶出介质,转速为100r? min -1,取样时间为1、2、4、6、8、10、12h。结果头孢克洛在40.4~202μg? mL -1范围内线性关系良好(r=0.9999);平均回收率为98.8%(RSD=0.91%),3批样品释放平稳,12 h平均溶出度均在95%以上。结论本方法便捷、准确、重现性好,可用于头孢克洛缓释胶囊的质量控制。
目的:建立頭孢剋洛緩釋膠囊體外釋放度的測定方法。方法採用溶齣度第一法,以水900mL為溶齣介質,轉速為100r? min -1,取樣時間為1、2、4、6、8、10、12h。結果頭孢剋洛在40.4~202μg? mL -1範圍內線性關繫良好(r=0.9999);平均迴收率為98.8%(RSD=0.91%),3批樣品釋放平穩,12 h平均溶齣度均在95%以上。結論本方法便捷、準確、重現性好,可用于頭孢剋洛緩釋膠囊的質量控製。

OBJECTIVE To study on release rate in vitro method of cefaclor release capsule .METHODS The dissolution of cefaclor release capsule was determined by dissolution test method 1.Water 900 mL was taken as solvent with the rotating speed at 100 r? min -1 , and the sampling time was 1、2、4、6、8、10、12 h.RESULTS The linear range of cefaclor was 40.4 ~202μg? mL-1 ( r =0.9999 ) , with average recovery rate at 98.8%( RSD =0.91%).The dissolutions of three groups of samples were smooth ,the 12h average dissolutions were above 95%.CONCLUSION The method is simple ,accurate and reproducible ,and can be used for the quality control of this preparation.
