Abstract

1 Levorphanol was 20 times more potent than dextrorphan in decreasing food-reinforced fixed ratio 15 responding in male Sprague Dawley rats. 2 Chronic dextrorphan (100 mg/kg, i.p.; every 8 h) resulted in the development of dextrorphan tolerance. The dextrorphan dose-effect curve was shifted to the right three fold. 3 In contrast to dextrorphan, nontolerance developed to the effects of levorphanol. 4 These data support the hypothesis that (+)-isomers of opioids produce pharmacologically distinct CNS effects.

摘要

1 左啡诺在降低雄性斯普拉格-道利大鼠食物强化固定比率15反应方面的效力比右啡烷强20倍。2 慢性给予右啡烷（100毫克/千克，腹腔注射；每8小时一次）导致右啡烷耐受性的产生。右啡烷的剂量-效应曲线向右移动了三倍。3 与右啡烷相反，左啡诺的作用未产生耐受性。4 这些数据支持了阿片类药物的（+）-异构体产生药理学上不同的中枢神经系统效应这一假说。
