Brief Summary  
Clozapine, a dibenzodiazepine derivative with potent antipsychotic properties, is indicated for the management of patients with severe schizophrenia who fail to respond adequately to at least two different antipsychotic drug treatments. In this study, the steady state pharmacokinetics and food effect of clozapine ER capsules of Intas Pharmaceuticals Limited, India (test formulation) will be assessed after multiple dose administration to adult, schizophrenic patient in a crossover design study. The Sponsor has developed an extended release formulation of clozapine. This formulation being extended release formulation, it is expected to improve the compliance, reduce drug free interval and reduce side effects which is very important considering schizophrenic population. This study is being conducted to characterize and compare the pharmacokinetic profile of the Sponsor’s formulation clozapine extended release capsule 200 mg (Test drug, Intas Pharmaceuticals Ltd., India) when administered once daily under fasting and fed condition. As a high number of healthy Patients experienced serious adverse effects after administration of antipsychotics such as hypotension, tachycardia etc., hence, regulatory authorities are recommending that studies should be conducted on Schizophrenic patients. The study is being conducted on schizophrenic patients, who are on a stable dose of clozapine, and the patients cannot be deprived of the clozapine while on treatment, the study has been planned to be a continuous administration of the test formulation without any intervening washout period.
