Comparison of Intramuscular Olanzapine Depot to Oral Olanzapine and Low-Dose Depot in Patients With Schizophrenia

Summary

This is a randomized, double-blind study to determine how well intramuscular (IM) olanzapine depot works compared to oral olanzapine; evaluate the safety and tolerability of IM olanzapine depot compared to oral olanzapine; evaluate different doses of IM olanzapine depot; and determine the blood levels of IM olanzapine depot in patients at different points in time after an injection.
