Rapid improvement of tardive dyskinesia with tetrabenazine, clonazepam and clozapine combined: a naturalistic long-term follow-up study.

摘要

Tardive dyskinesia (TD) is a complex involuntary movement disorder affecting about 23% of neuroleptic-treated patients. Our objective was to retrospectively analyze a combination of tetrabenazine (TBZ), clonazepam (CLONAZ) and clozapine (CLOZ) used simultaneously for TD in psychotic patients. Six patients with severe, unsuccessfully controlled TD were referred for treatment (mean age 51.5 years; three male; four schizophrenics; one bipolar disease; one borderline personality disorder). They were being treated with neuroleptics (classic, three; risperidone, two; olanzapine, one) and developed severe neck and buccolingual dyskinesias. At our clinic, all of them were treated simultaneously with TBZ (mean dose 141.6?mg); CLONAZ (mean dose 4.3?mg); and CLOZ (mean dose 125?mg). In parallel, we stopped the offending medication. With 1?week, we observed a very impressive improvement in symptoms and within 1?month all the patients were free of symptoms. The mean observation period was 4?years. The combination of TBZ, CLONAZ and CLOZ is a rapid and beneficial option for the management of TD. An augmentation effect probably played a role in the rapid alleviation of symptomatology.
