Results

Results: It was not conclusive about the primary outcome measure because the number of patients allocated to each treatment group was approximately 60% of the required number of patients set by power analysis. The Negative score of the Positive and Negative Syndrome Scale was significantly higher in high-dose patients than in conventional-dose patients. Serum olanzapine concentrations at the timing of oral 20 mg/day could be obtained from 5 out of 7 patients who subsequently required high-dose olanzapine. All values reached a therapeutic range of 20-50 ng/mL, and the mean value was 47.876 (SD 21.546) ng/mL.
Conclusion: The present study has shown evidence that the reason for requiring high-dose olanzapine cannot be explained by pharmacokinetics for the first time.
