Pharmacologic and cognitive behavioral therapies have been advocated in the treatment of bulimia nervosa (BN). Brofaromine, a selective and reversible inhibitor of monoamine oxidase-A was selected for a double-blind, placebo-controlled evaluation because of previous demonstrated monoamine oxidase inhibitor efficacy in BN and because of its safer adverse reaction profile. Thirty-six female patients who met DSM-III-R criteria for BN were randomly assigned to the drug group (N = 19) or to the placebo group (N = 17) for an 8-week outpatient trial. Brofaromine produced a significant effect in decreasing episodes of vomiting throughout the trial, although comparable reductions in episodes of binge eating were found in both groups. Also, there were no advantages of drug over placebo on improvements in attitudinal measures and shape or on self-report ratings of depression and anxiety. However, a significant proportion of the subjects on brofaromine lost weight when compared with the placebo group. Methodologic issues including subjective assessment measures, placebo response rates, and the elucidation of responder subgroups are discussed.
药物治疗和认知行为疗法已被提倡用于治疗神经性贪食症(BN)。由于先前已证明单胺氧化酶抑制剂对神经性贪食症有效,且其不良反应谱更安全,因此选择了吗氯贝胺(一种选择性且可逆的单胺氧化酶-A抑制剂)进行双盲、安慰剂对照评估。36名符合DSM-III-R神经性贪食症标准的女性患者被随机分配到药物组(N = 19)或安慰剂组(N = 17),进行为期8周的门诊试验。在整个试验过程中,吗氯贝胺在减少呕吐发作方面产生了显著效果,尽管两组在暴饮暴食发作次数上的减少程度相当。此外,在态度测量、体型改善或抑郁和焦虑的自我报告评分方面,药物组与安慰剂组相比并无优势。然而,与安慰剂组相比,服用吗氯贝胺的受试者中有很大一部分体重减轻。本文讨论了包括主观评估措施、安慰剂反应率和反应亚组阐明等方法学问题。
