Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are children aged 6 to 18 years with a clinical diagnosis of autism spectrum disorder and comorbid behavioral issues who are starting treatment with risperidone.
✕Probably not a fit
Patients with diabetes, certain congenital syndromes, or those who have recently been treated with antipsychotic medications may not benefit from this study.

What this trial studies
This study aims to evaluate the safety and pharmacokinetics of risperidone in children aged 6 to 18 years diagnosed with autism spectrum disorder and behavioral problems. It focuses on the use of therapeutic drug monitoring to manage the medication's dosage effectively, potentially reducing metabolic side effects while maintaining its clinical effectiveness. The study will involve monitoring plasma levels of risperidone to tailor treatment for individual patients. Participants will be recruited from the Erasmus Medical Center in Rotterdam.
Why it matters
Potential benefit: If successful, this approach could lead to safer and more effective treatment options for children with autism spectrum disorder.
How similar studies have gone: Other studies have shown promise in using therapeutic drug monitoring for antipsychotics, suggesting this approach may be beneficial.
