The present invention provides methods for purifying, identifying and using optically active isomers of quinine and quinidine as well as compositions comprising such optically active isomers. Such optically active isomers having desired actions on cardiac sodium and potassium channel function substantially separable from undesirable effects on GI motility can be useful for more effective therapy of cardiac arrhythmias. Also disclosed are methods for assaying the levels of such isomers present in the biological fluids.
本发明提供了纯化、鉴定和使用奎宁和奎尼丁的光学活性异构体的方法,以及包含这种光学活性异构体的组合物。这种光学活性异构体对心脏钠和钾通道功能的预期作用与对胃肠道蠕动的不良影响基本分离,可用于更有效地治疗心律失常。此外,还公开了用于检测生物液体中存在的此类异构体水平的方法。
