[Effectiveness of zotepine in therapy-refractory psychoses. An open, multicenter study in eight psychiatric clinics].
Zotepine was administered to 45 patients suffering from therapy-resistant psychoses hospitalized in eight psychiatric institutes (University Hospital Okayama and affiliated institutions). The psychoses of these patients were characterised by positive symptoms--predominantly hallucinations and delusions--and could not be influenced by a large variety of conventional antipsychotics, such as haloperidol. Previous medications were discontinued or administered together with zotepine. To assess changes in the pattern of symptoms, the Brief Psychiatric Rating Scale (BPRS) was employed over a period of up to 12 weeks at 2-week intervals. Ten patients dropped out of the study because of undesirable effects or for other reasons. 35 patients completed the 12-week study according to schedule. There was a relation between general improvement and certain patient characteristics. Zotepine proved to be effective especially in the catatonic type of schizophrenia, in chronic schizophrenias with acute exacerbation (DSM-III) and in relatively young patients in whom the disease had existed for a short time only. In the 26 patients who were markedly, moderately or slightly improved, BPRS score had dropped significantly after only two weeks of treatment. This points to a rapid onset of the therapeutic action of zotepine.
