Hypothesis

Does differential anti-depressive effectiveness exist among second generation antipsychotics in patients acutely admitted with psychosis?

Conclusion

There was no substantial difference in anti-depressive effectiveness among olanzapine, quetiapine, risperidone, or ziprasidone in patients with psychosis.

Supporting Evidence

  • A significant time-effect showing a steady decline in depressive symptoms was demonstrated.
  • There were no substantial differences among the SGAs in reducing the PANSS-D score or the CDSS sum score.
  • The study was funded independently of the pharmaceutical industry.

Takeaway

The study looked at different medications for depression in people with serious mental health issues and found that none worked better than the others.

Methodology

Patients were randomized to receive one of four medications and followed for up to 2 years, with assessments of depressive symptoms at multiple time points.

Potential Biases

Potential bias due to the open randomization process and the high attrition rate.

Limitations

The study's sample was heterogeneous, and the randomization process allowed for some bias in medication choice.

Participant Demographics

Adult patients acutely admitted for psychosis, with a diverse range of diagnoses.
