title: Citalopram in patients with unsatisfactory response to neuroleptics: an open follow-up study.
abstract: There is clinical evidence that antidepressants have beneficial effects on certain symptom clusters of psychotic patients. Specific serotonin reuptake inhibitors like citalopram provide a new possibility to selectively influence brain neurotransmission. We studied the effects of citalopram (20-60 mg daily) in 36 psychotic or borderline patients receiving neuroleptic treatment without satisfactory response. Particular attention was paid to negative symptomatology, anxiety, and impulsiveness. 22 of the patients (65%) were assessed to react to citalopram treatment in a clinically significant manner. Initially, the responders tended to have higher scores in withdrawal-retardation, anxious-depression, and hostile-suspiciousness factors of the Brief Psychiatric Rating Scale (BPRS), with a lower degree of thinking disturbances. In the responder group, a significant decline in all symptom clusters was recorded. The mean decrease was 38% in Clinical Global Impression (CGI) and BPRS scales. The most prominent change (52%) was seen in hostile-suspiciousness factor of the BPRS inventory. In light of the positive results achieved in this open-label trial, controlled trials with patients not responding satisfactorily to neuroleptics are warranted.
