Schizophrenia is a severe chronic and disabling mental disorder and is associated with a significant reduction in life expectancy. Atypical antipsychotic treatment compliance may be jeopardized because of drug induced weight gain and abnormalities in carbohydrate and lipid metabolism.

Aim: to gain data on drug related effects on gene expression and regulation with special regard to glucose metabolism.

Condition Intervention Phase
Drug: olanzapine
Drug: ziprasidone
Drug: placebo
Phase 4

Intervention Model: Parallel Assignment
Masking: Double Blind (Subject, Outcomes Assessor)
