摘要
目的:用美国药典流通池方法测试雷帕霉素药物洗脱冠脉支架体外释放度,作为企业出厂检验方法,以评价其工艺稳定性。方法:用美国药典释放度测定第4法规定的溶出装置联机紫外分光光度计。释放介质为2%十二烷基硫酸钠溶解在10%乙腈-PBS(pH=5.0)的缓冲液;检测波长为280 nm。结果:相同批号(n=6)和不同批号(n=3)的药物支架的雷帕霉素在24 h的释放曲线一致。结论:本法适合评价冠脉支架涂药的工艺稳定性,快速简便,符合美国药典流通池法的要求,检测结果较为满意。
Objective:To establish a method for the analysis of release of rapamycin in drug eluting stents(DES) with flow-cell elution system.Method:Dissolution test method(modify USP 4) was adopted and used 50 mL the mixture of 2% SDS and 10% acetonitrile in PBS buffer(pH=5)as the release media.Keep the detective wavelength at 280 nm.Result:The release of rapamycin is identical to which between the same lots and different lots.Conclusion:The method is fast and convenient.
