Novel antipsychotics for patients with attention-deficit hyperactivity disorder: a systematic review
Einarson T R, Iskedjian M
Record ID 32002000017
This report aims to answer the following questions:
- What does the existing evidence say about the efficacy and safety of novel antipsychotics for treating children and adolescents with attention-deficit hyperactivity disorder (ADHD)?
- What are the financial implications, in terms of additional drug acquisition costs, for the Canadian health care system if novel antipsychotics were to be adopted for this indication?
Authors' results and conclusions: Efficacy: A formal meta-analysis could not be performed due to the lack of data. Case studies considering the use of risperidone and olanzapine, either alone or as add-on therapy with methylphenidate, for the treatment of ADHD reported successes, failures and discontinuations due to adverse events. As those studies are not controlled or comparative, it was not possible to draw any conclusions about the efficacy of the treatment. Safety: A total of 549 children and adolescents were reported to have taken either risperidone or olanzapine in 49 Level III studies. There were no accounts of pediatric quetiapine use in the literature. The most common adverse drug reaction (ADR) was sedation, which usually dissipated either on its own or after a dose reduction. Many children experienced weight gain. The literature also reported extrapyramidal effects in 4% of the patients.
Authors' recommendations: As the quality of the existing evidence is quite weak, no conclusions can be drawn concerning the efficacy of novel antipsychotics for treating children and adolescents with ADHD.
