A control study of risperidone and clozapine in the treatment of the negative symptoms of schizophrenia

OBJECTIVE:To compare the therapeutic effect of risperidone and clozapine on the negative symptoms of schizophrenia.METHODS:Twenty schizophrenic patients were treated with risperidone and tewnty schizophrenic patients with clozapine. Both were assessed with the SANS and TESS, double blind, before and after treament to evaluate the effects on negative symptoms. RESULT:Both drugs were effective in treating the negative symptoms of schizophrenia (p>0 05). While risperidone has fewer side effects than clozapine. CONCLUSION:Clozapine's superior effect on negative symptoms of schizophrenia may be related to its affinity to 5-HT receptors. So is risperidone. And risperidone's fewer side effects may be related to its equal affinity to 5-HT and DA receptors.
