我们进行了一项研究,使用离散试验选择程序评估异丙酚在人类中的奖励效果。正常健康志愿者(n = 12)以盲法暴露于2次0.6 mg/kg异丙酚急性大剂量注射和2次等量的Intralipid®。然后,在接下来的三个疗程中,受试者选择他们希望接受的药物(用颜色代码标识)。我们将选择异丙酚者定义为两次或三次选择异丙酚者,将不选择异丙酚者定义为一次或根本不选择异丙酚者。通过随机选择模型的χ2拟合优度检验,选择分布与随机选择分布有显著差异(P < 0.005)。6名受试者为选择者:4名受试者在所有3个选择场合选择丙泊酚,2名受试者在2/3个选择场合选择药物(以下简称丙泊酚选择者)。6名受试者不选择:5名受试者在所有三次选择中都选择了Intralipid®,1名受试者两次选择Intralipid®(以下称为异丙酚不选择者)。在抽样过程中,选择异丙酚的人报告了愉快的急性效应,没有令人不快的残留效应,而不选择异丙酚的人报告了不愉快的急性主观效应和/或异丙酚的残留效应。我们的结论是:1)异丙酚对一些没有药物滥用史的个体可能是有益的(强化的);2)需要对这种药物进行进一步的滥用责任测试。
We conducted a study in which the rewarding effects of propofol were assessed in humans, using a discrete-trials choice procedure. Normal healthy volunteers (n = 12) were exposed in a blind fashion to acute bolus injections of 0.6 mg/kg of propofol twice and to a similar volume of Intralipid® twice. Then, for the next three sessions, subjects chose which drug (identified by a color code) they wished to receive. We defined propofol choosers if individuals chose propofol two or three times, and nonchoosers if they chose propofol once or not at all. By using a χ2 goodness-of-fit test of a random choice model, the choice distribution differed significantly from a random choice distribution (P < 0.005). Six subjects were choosers: four subjects chose propofol on all three choice occasions and two subjects chose the drug on 2/3 occasions (referred to hereafter as propofol choosers). Six subjects were nonchoosers: five subjects chose Intralipid® on all three choice occasions, and one subject chose Intralipid® twice (referred to hereafter as propofol nonchoosers). During sampling sessions, propofol choosers reported pleasant acute effects and no unpleasant residual effects, whereas propofol non-choosers reported either unpleasant acute subjective effects and/or residual effects from propofol. We conclude that 1) propofol may be rewarding (reinforcing) in some individuals without a history of drug abuse, and 2) further abuse liability testing is needed with this drug.
