title: Buspirone in the treatment of tardive dyskinesia.
abstract: Eight patients with mild to severe tardive dyskinesia (TD) were treated for 12 weeks with buspirone in dosages of up to 180 mg/day in an open-label study. Changes in TD severity were assessed by the Abnormal Involuntary Movement Scale. The rater was blind to buspirone dosage. Buspirone was well tolerated by most subjects. A within-subjects comparison of pretreatment and post-treatment Abnormal Involuntary Movement Scale scores revealed a mean improvement of 4.4 (p < 0.01). Improvement was also observed in neuroleptic-induced extrapyramidal side effects such as parkinsonism and akathisia. Scores on the Hamilton Rating Scale for Anxiety and the Brief Psychiatric Rating Scale did not change during the 12-week study. The results of this open-label pilot study suggest that relatively high doses of buspirone may be efficacious in the treatment of TD.
