一般描述

用于质量控制的制药二级标准品,为制药实验室和制造商制备内部工作标准品提供了一种方便、高性价比的替代方案。
Levitiracetam是吡拉西坦的类似物,是一种抗癫痫药物,广泛用于治疗癫痫发作,包括局部和全局性癫痫。

应用

Levitiracetam可用作药物参考标准品,通过多种色谱技术和分光光度技术测定药物制剂中的分析物
这些二级标准品是合格的认证标准物质(CRM)。它们适用于多种分析应用,包括但不限于药物释放测试、药物的定性和定量分析方法开发、食品和饮料质量控制检测以及其他校准需求。

生化/生理作用

左乙拉西坦是一种具有抗癫痫活性的吡咯烷。左乙拉西坦的立体选择性结合仅限于中枢神经系统的突触质膜,而在周围组织中不发生立体选择性结合。左乙拉西坦在不影响正常神经元兴奋性的情况下抑制簇状放电,这表明它可以选择性地阻止癫痫样簇状放电的超同步和发作活动的传播。

分析说明

这些二级标准品可追溯至USP、EP和BP一级标准品。

其他说明

该认证标准物质(CRM)根据ISO 17034ISO/IEC 17025进行生产和认证。有关此CRM使用的所有信息均可在检验报告上找到。

附注
