OBJECTIVE: To examine the change in Framingham risk score (FRS) arising from short-term treatment with ziprasidone or olanzapine. METHOD:Hospitalized adults with a primary DSM-IV diagnosis of schizophrenia or schizo-affective disorder were randomly assigned to 6 weeks of double-blind treatment with ziprasidone or olanzapinefrom November 21, 1998 to September 28, 2000. Data on fasting lipid levels were collected at screening and endpoint, and blood pressure was measured at screening and baseline and weekly until week 6 of treatment (or last visit). FRS for patientsaged ≥30 years was calculated using an algorithm derived from the Framingham Heart Study. Baseline-to-endpoint least-squares mean changes in age-adjusted FRS by gender were compared using analysis of covariance (baseline adjusted). RESULTS: Men who received olanzapine demonstrated a mean increase in their total cholesterol levels (+18.5 mg/dL; N = 53) and low-density lipoprotein cholesterol levels (+13.0 mg/dL; N = 45), whereas men who received ziprasidone demonstrated a mean decrease in their total cholesterol levels (-8.5 mg/dL; N = 44) and low-density lipoprotein cholesterol levels (-7.2 mg/dL; N = 40) (p = .0006 and p = .004, respectively). Additionally, men who received olanzapine showed an increase in baseline FRS (+7.69%; N = 53), whereas men who received ziprasidone showed a decrease in baseline FRS (-11.06%; N = 42) (p = .09). In women, treatment differences in FSR numerically favored ziprasidone but were not statistically significant. Neither treatment had a significant effect on blood pressure. CONCLUSION: In short-term treatment, olanza-pine was associated with a significant worsening of lipid profile compared with ziprasidone, with a consequent increase in FRS versus ziprasidone. These findings, coupled with the significant weight gain in patients treated with olanzapine versus ziprasidone, warrant investigation in longer-term trials.
