Treatment Respose in Olanzapine-treated
patients with Schizophrenia

Objective: The aim of this study was to explore the treatment effect of olanzapine
on the polymorphisms of monoamine oxidase A (MAOA) in schizophrenia.
Method: During a 3-month period, 60 patients with schizophrenia were administered
olanzapine. Treatment response was assessed by checking for improvement
in symptoms as measured on the Positive and Negative Syndrome Scale (PANSS).
Results: The short form of MAOA demonstrated a better drug response in the dimension
of aggression. Female patients had a better response to olanzapine. Patients
who did not smoke had a better response to olanzapine in the dimension of
aggression. Conclusion: The results of this study suggest that polymorphisms of
MAOA, gender, and cigarette smoking may be three useful response predictors in
schizophrenic patients who were treated with olanzapine.
