Pimozide combined with behavior therapy in the short-term treatment of anorexia nervosa. A double-blind...

Eighteen female inpatients were included in a double-blind placebo-controlled cross-over study aimed at testing the hypothesis that dopamine blockade may enhance the effectiveness of behavior therapy in the short-term weight restoration of anorexia nervosa patients. The patients were given a uniform contingency management program and, after a baseline period, they alternatingly (3-week periods) received pimozide (4 to 6 mg) or a placebo. During the first two periods pimozide almost significantly enhanced the weight gain induced by the behavior therapy program and beneficially influenced the patients' attitude towards treatment.
