title: Open assessment of the safety and efficacy of thioridazine in the treatment of patients with borderline personality disorder.
abstract: A 12-week open study was conducted to assess the possible efficacy and safety of low-dose thioridazine in 11 outpatients (8 women, 3 men) with borderline personality disorder (BPD) diagnosed according to DSM-III-R (American Psychiatric Association 1987) and the Diagnostic Interview for Borderline Patients (DIB; Gunderson et al. 1981) criteria. Mean thioridazine dose averaged 92 mg per day across the duration of this study. At endpoint, there was a significant reduction in Brief Psychiatric Rating Scale (BPRS; Overall & Gorham 1988) scores, and patients appeared to be less symptomatic on the impulse action patterns, affects, and psychosis subscales of the DIB (modified to assess change). Subjects completing the entire study (n = 6) also showed improvement in interpersonal relations. On self-report measures, significant improvement was noted on most Hopkins Symptom Checklist-90 (SCL-90; Derogatis et al. 1973) subscales, particularly in hostility and additional depressive features. Subjects completing the entire study showed significant improvement in paranoid ideation, interpersonal sensitivity, and anxiety. Three patients, however, developed sustained melancholic depressions that necessitated their discontinuation from the study and the initiation of anti-depressant treatment. These three individuals were more schizotypal, schizoid, and paranoid at baseline according to Personality Disorder Examination (PDE; Loranger et al. 1987) structured interviews. Weight gain was not a significant problem, but sedation and erectile dysfunction were. Overall, these findings suggest that thioridazine may exert prominent effects on patients with BPD and that double-blind, placebo-controlled studies are warranted.
