国产与原研苯磺酸左旋氨氯地平片体外溶出曲线一致性评价

摘要仿制药在我国医药市场占有很大的比例，对解决我国人民缺医少药的问题有重大意义。国务院发布的《国家药品安全“十二五”规划》中就明确提出了要全面提高仿制药质量，开展仿制药质量的一致性评价。本文主要采用紫外分光光度法测定4种不同厂家生产的药品在不同介质（pH 1.0、pH 1.2、pH 2.0、pH 4.0、pH 6.8和水）中不同时间点的体外溶出情况，采用f2因子法比较溶出曲线，以进行一致性评价。结果表明，苏州东瑞制药的安美平和江西施美制药的施美力健与辉瑞制药的络活喜溶出曲线基本相似，溶出行为有较小差异(除去水介质中的)。北京红林制药的久保舒在偏酸介质（pH=1.0、pH=1.2）溶出情况与进口药络活喜有较大差异。52543

Title Evaluation of Domestic and Imported Levamlodipine Besylate Tablets in Vitro Dissolution Profile Consistency

Abstract

Generics account for a large proportion in Chinese pharmaceutical market,have great significance to solve the problem of shortage of doctors and medicine in China.The State Council issue “the plan of national drug safety in 12th Five-Year”made it clear that we should comprehensively improve the quality of genertic drugs,to carry out quality consistency evalution of generic drugs.In this paper,UV spectrophotometry was used to determine the dissolution of 4 different kinds of drugs at different time points in different medium(pH 1.0,pH 1.2,pH 2.0,pH 4.0,pH 6.8 and water).Using f2 factor method to compare dissolution curve,in order to evaluate the consistency.The results show that Anmeipin’s and Shimeilijian’s dissolution curve is similar with Norvasc’s dissolution curve ,there are minor difference in dissolution behavior,except in the water.But Jiubaoshu dissolution condition is different from Norvasc in partial acid medium(pH=1.0 and pH=1.2).
