Brief Summary

Primary Objective: To compare added metformin and/or added simvastatin versus no intervention in reducing or eliminating increased cardiovascular risk (as estimated by elevation in non-HDL cholesterol levels) during the treatment of schizophrenia with olanzapine. Secondary Objective(s): To compare added metformin and/or added simvastatin versus no intervention in reducing or eliminating increased cardiovascular risk (as estimated by elevation in triglyceride levels) during the treatment of schizophrenia with olanzapine. To compare added metformin and/or added simvastatin versus no intervention in reducing or eliminating increased cardiovascular risk (as estimated by C-reactive protein levels) during the treatment of schizophrenia with olanzapine

Eligibility Criteria

Age18 Years - 60 Years
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64)

You may qualify if:

  • We will include patients who come to us free of antipsychotic medication, i.e., patients with chronic schizophrenia (with at least one prior psychiatric hospitalization) who have been off antipsychotic medication for at least 3 weeks and who are newly hospitalized for treatment of an acute psychotic relapse; these patients will be male or female, 18-60 years of age, meet DSM-IV criteria for schizophrenia, and have scores \>=4 on at least two of the PANSS Positive subscale items.

You may not qualify if:

  • We will exclude patients whose psychoses are predominantly affective in nature or explainable on the basis of substance abuse or a co-morbid medical condition, patients with diabetes mellitus, epilepsy, mental retardation, or organic mental syndromes, and patients currently taking metformin or a statin.
