title: Comparison of effects of olanzapine and risperidone on body mass index and blood sugar level in schizophrenic patients.
abstract: Schizophrenia is one of the most debilitating disorders with devastating effects on its victims and their families. Atypical antipsychotics (AAPs) because of their superior efficacy, reduced side effects, & better compliance, have rapidly become the mainstay of treatment. But, because of paucity of research & literature on the long-term metabolic side effect profile of these AAPs in Indian setup, this prospective study has been carried out to compare the effects of olanzapine & risperidone on body weight, body mass index, & blood sugar level in schizophrenic patients. Among 60 newly diagnosed DSM-IV patients of schizophrenia enrolled, it was observed that mean body weight & BMI were significantly increased from baseline to 6 & 12 weeks in both olanzapine (n = 30) & risperidone groups (n = 30) (P < 0.001). Also, mean blood sugar was found to be significantly elevated after 6 & 12 weeks of treatment with olanzapine (P < 0.001) but not in risperidone group. Thus, the present study underscores the need for baseline and six weekly monitoring of body weight and blood glucose in routine clinical practice with AAPs.
