[Effectiveness and tolerance of zotepine in a double-blind comparison with perazine in schizophrenic patients]

40 inpatients suffering from a schizophrenia (ICD-9) were treated with either zotepine or perazin. The study was continued for a period of 28 days. Assessment of clinical efficacy was effected via BPRS, AMDP, CGI and SANS; tolerance was assessed by means of Simpson's scale. In addition, EEG, ECG and laboratory controls were conducted. The overall therapeutic efficacy was good, and it was not possible to distinguish one group from the other, i.e. both substances were equally effective, judged by means of the psychopathometric tools that were at our disposal. In 11 patients of the zotepine group and in 9 patients of the perazin group, slight extrapyramidal symptoms were observed. No clinically relevant changes were seen in EEG, ECG and laboratory controls in both groups.
