目的:确定氟哌啶醇治疗首发精神病的最佳剂量。方法:一项为期4周的前瞻性对照临床试验,“最佳剂量”定义为发生以下两种情况之一的剂量:1)显著改善,定义为阳性和阴性症状量表(PANSS)得分下降15%或以上,或2)锥体外系症状的出现。从每天2毫克开始,氟哌啶醇每周增加到5毫克,10毫克,最后每天20毫克,直到1)或2)发生。结果:36例受试者的最佳剂量分别为15例每日2 mg,11例每日5 mg,7例每日10 mg,3例每日20 mg。平均而言,每日最佳剂量为2 mg的受试者效果最好。在27例有临床疗效的受试者中,有20例的血浆氟哌啶醇水平低于5 ng/ml。结论:许多首发精神病患者对氟哌啶醇的剂量反应远低于常用剂量。
Objective: To determine optimal doses of haloperidol for the treatment of a first episode of psychosis. Method: A 4-week prospective controlled clinical trial with “optimal dose” defined as the dose at which either of the following occurs: 1) significant improvement, defined as a 15% or greater decrease in scores on the Positive And Negative Syndrome Scale (PANSS), or 2) the onset of extrapyramidal symptoms. Beginning with 2 mg daily, haloperidol was increased weekly to 5 mg, 10 mg, and finally 20 mg daily until either 1) or 2) occurred. Results: Optimal doses for the 36 subjects were 2 mg daily for 15 subjects, 5 mg daily for 11, 10 mg daily for 7, and 20 mg daily for 3. On average, subjects whose optimal dose was 2 mg daily showed the greatest improvement. Among the 27 subjects evidencing clinical response to treatment, 20 had plasma haloperidol levels below 5 ng/ml. Conclusion: Many people suffering a first psychotic episode respond to haloperidol doses well below levels in common use.
