A three-year naturalistic follow-up of patients receiving clozapine: Report from India

Abstract

INTRODUCTION: Clozapine is a first-line drug for treatment-resistant schizophrenia, but studies dealing with long-term outcome are lacking, so we decided to carry out such a study. METHODS: Patients with treatment-resistant schizophrenia who were recruited in an open-label study three years ago were re-evaluated using the same parameters: BPRS, PANSS and a side-effect rating checklist. RESULTS: Nineteen out of 25 patients who participated in the initial study were available for re-evaluation. Two patients had changed to conventional neuroleptic medication, and were excluded from the study. A significant reduction in psychopathology was observed in 85% of patients. An improvement in social functioning was evident, with seven patients pursuing a career independently, and another six working with their family members since being started on clozapine. All the patients were on clozapine monotherapy, and the average daily dose was 248.21 mg. No patient required hospitalization and there was no incidence of granulocytopenia. CONCLUSIONS: A significant improvement in the psychopathology and social functioning of patients was observed with much lower doses of clozapine than has been reported elsewhere. The doses used for maintenance were lower than those used in the acute phase of treatment. (Int J Psych Clin Pract 2002; 6: 167-171 )
