A compound is shown in formula I and can be in the form of a pharmaceutically acceptable salt, or a stereoisomer, or a solvate, or a prodrug, or a metabolite. The compound takes effect rapidly and has a long-time local anesthetic effect following a single dose, with the sensory nerve blocking time being greater than the motor nerve blocking time, has both a long-acting local anesthetic effect and a selective local anesthetic effect, significantly reduces side effects of the compositions QX314 and QX314 and a quaternary ammonium salt compound with surfactant structural characteristics, and is safer. The compound of formula I of the present invention and a pharmaceutically acceptable salt thereof can be used for preparing drugs that have a long-time local anesthetic effect and a selective local anesthetic effect.
化合物在公式I中显示,可以是药学上可接受的盐的形式,或立体异构体,或溶剂合物,或前药,或代谢物。该化合物作用迅速,单剂量后具有长时间的局部麻醉效果,感觉神经阻滞时间大于运动神经阻滞时间,既具有长效局部麻醉效果又具有选择性局部麻醉效果,显著减少了QX314和QX314组分以及具有表面活性剂结构特征的季铵盐化合物的副作用,并且更安全。本发明的公式I的化合物及其药学上可接受的盐可用于制备具有长效局部麻醉效果和选择性局部麻醉效果的药物。
