Summary

This completed study compared two schizophrenia medications, aripiprazole and risperidone, in 60 patients to see how they affect mitochondria—the energy factories inside cells. Researchers measured changes in mitochondrial activity and related blood markers over 12 weeks. The goal was to understand if these drugs cause cell energy problems that might lead to side effects.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Aripiprazole and Risperidone
What this could lead to
If successful, this could help explain why some antipsychotics cause side effects like movement problems, potentially guiding safer treatment choices.
What could go wrong
This is a small, completed study measuring biological markers, not clinical outcomes. Results may not change treatment or apply to all patients.
