左旋甲基苯丙胺


左旋甲基苯丙胺 (levomethamphetamine)[note 1]又称左旋甲基安非他命,是右旋甲基苯丙胺光学异构体左旋甲基苯丙胺拟交感神经血管收缩剂,是一些非处方(OTC) 鼻腔去阻塞吸入剂英语nasal decongestant的活性成分[note 2]

药理学特性

左旋甲基苯丙胺可穿越血脑屏障并作为TAAR1激动剂英语TAAR1 agonist[3],也作为去甲肾上腺素释放剂英语norepinephrine releasing agent (对多巴胺系统较无影响[4])。它跟右旋甲基苯丙胺一样影响中枢神经系统,但作用方式不同[5]。不同于右旋甲基苯丙胺,它在低剂量没有造成欣快成瘾的特性[5][6][4]。在他的几项生理作用中,血管收缩作用使其可用于去鼻腔阻塞喷剂[7]

左旋甲基苯丙胺的半衰期约为13.3至15小时,右旋甲基苯丙胺则为10.5小时[8]
