Efficacy of risperidone and haloperidol in treatment of schizophrenia in tertiary care hospital

Lavanya Nagaraj, Naveen Kumar Madalageri


Background: Schizophrenia is a chronic debilitating disease with significant morbidity and mortality that often requires either typical or atypical antipsychotic pharmacotherapy. Atypical antipsychotic drugs are preferred over typical because of lower risk of extra pyramidal side effects. As there is paucity of data in Indian population, the present study was taken up to evaluate the efficacy of haloperidol and risperidone in the treatment of schizophrenia.

Methods: It was a comparative study conducted on 60 patients of Schizophrenia for one year in a tertiary care hospital. The study subjects were randomly assigned into 2 groups of 30 patients each, where group 1 were treated with atypical antipsychotic drug risperidone and group 2 with typical antipsychotic drug Haloperidol and both groups received the treatment for one year. Efficacy was measured using positive and negative syndrome scale (PANSS), clinical global impression - severity of illness (CGI-S), clinical global impression - improvement (CGI-I) scales.

Results: Both haloperidol and risperidone were associated with comparable baseline to endpoint reduction in symptom severity. However, risperidone treated subjects had significantly greater decrease in symptom severity as measured by PANSS score and total score, CGI-S scale. However, there is no significant difference between two groups in terms of CGI-S score.

Conclusions: The reduction in positive, negative and general scores in risperidone treated patients were significant with that of haloperidol treated patients.
