Patients are randomized to either olanzapine or haloperidol groups.

The duration of intervention is about 30 minutes after single dose of study drug. The dose of olanzapine and haloperidol are both intramuscularly 10mg. The estimated study period will be approximately one year and the sample size is approx 140 in each study group i.e. 280 subjects in total.
