Study type
Interventional
Description of intervention(s) / exposure
Patients are randomized to either olanzapine or haloperidol groups. The study aim is to compare the time for sedation of acutely agitated patients in the olanzapine group (new treatment) with haloperidol group (traditional treatment). 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.
