Study Summary
🔬
What They Studied
The study aimed to evaluate the efficacy and tolerability of atomoxetine for treating ADHD in 5- and 6-year-old children.
💡
What They Found
Atomoxetine was shown to significantly reduce ADHD symptoms according to parent and teacher reports, but overall improvement was limited based on clinical impression scales.
📚
What This Means
These findings suggest that while atomoxetine can reduce core ADHD symptoms, it may not lead to significant overall improvement in young children.
Study Summary
Study Overview
The study aimed to assess how effective atomoxetine is for treating ADHD in young children aged 5 and 6. It uniquely included a parent-education module alongside medication to ensure a more comprehensive approach.

While some children showed significant improvements, many still experienced notable ADHD symptoms by the study's end. This highlights the complexity of treating ADHD, especially in very young children, and suggests that more research is needed to explore long-term effects and responses to treatment.

Objective of the Study
"The objective of this study was to evaluate the efficacy and tolerability of atomoxetine for the treatment of ADHD in 5- and 6-year-old children."
Significance of Symptoms
"Although effective, clinically significant symptoms remained for the majority of children treated with atomoxetine."
First Assessment in Young Children
"This study provides the first randomized controlled data from children under the age of 6 years."
Study Summary
Methods
An 8-week clinical trial was conducted where neither the participants nor the researchers knew who received the active drug, atomoxetine, or a placebo. This approach is called double-blind.

During the study, doctors adjusted the medication dose as needed, up to a certain limit. They also provided parents with educational materials on managing ADHD symptoms and behaviors effectively.
Abstract: methods
This was an 8-week, double-blind, placebo-controlled randomized clinical trial of atomoxetine in 101 children with ADHD. Atomoxetine or placebo was flexibly titrated to a maximum dose of 1.8 mg/kg per day. The pharmacotherapist reviewed psychoeducati...more
Study Summary
Results
Atomoxetine led to notable improvements in ADHD symptoms, as reported by parents and teachers. However, only 40% of children on atomoxetine showed significant improvement, compared to 22% on placebo.

Side effects like decreased appetite, stomach issues, and drowsiness were more common with atomoxetine. While some children responded well, others showed less change, and still, many were moderately or severely affected by ADHD symptoms.
Abstract: results
Significant mean decreases in parent (P = .009) and teacher (P = .02) ADHD–IV Rating Scale scores were demonstrated with atomoxetine compared with placebo. A total of 40% of children treated with atomoxetine met response criteria (Clinical Global Imp...more
Study Summary
Conclusions
This study was groundbreaking, being the first to test atomoxetine in children as young as five years. The medication was mostly well-tolerated and helped reduce key ADHD symptoms.

Yet, despite some symptom improvements, many children remained significantly affected by their ADHD at the study's conclusion, highlighting that symptom reduction didn’t always equate to overall functional improvement.
Abstract: conclusions
To our knowledge, this is the first randomized controlled trial of atomoxetine in children as young as 5 years. Atomoxetine generally was well tolerated and reduced core ADHD symptoms in the children on the basis of parent and teacher reports. Reduct...more

Expert Opinion: Atomoxetine for ADHD in Young Children
In line with the abstract findings, atomoxetine shows efficacy in reducing core symptoms of ADHD but may offer a less robust effect compared to stimulant medications.

The guidelines suggest methylphenidate as an alternative for severe symptoms if behavioral interventions fall short.

Given atomoxetine's lower abuse potential compared to stimulants, it remains a viable option, despite the need for careful monitoring for suicidal ideation in children.

Preschool-aged children are advised to commence treatment with evidence-based behavioral interventions.
