Secondary

MeasureTime frame
Comparision the safety profile of Clozapine and ClozarilTimepoint: � The blood pressure, heart rate, respiratory rate and body temperature will be measured prior to dosing (within 120 minutes prior to dosing) on Days 01, 07, 08, 09 and 10 in each period. � The blood pressure, respiratory rate and heart rate will be measured at 1, 4 & 8 hours (± 30 minutes) post dose on Day 01 in each period. � The blood pressure, respiratory rate and heart rate will be measured at 1, 2, 4, 6 & 12 hours (± 30 minutes) post dose on Day 10 in each period
