OBJECTIVE: The primary objective of this study was to assess the impact of atomoxetine in combination with psychoeducation, compared with placebo and psychoeducation, on health-related quality of life (HRQL) in Swedish stimulant-naïve pediatric patients with attention deficit/hyperactivity disorder (ADHD). HRQL results will be presented elsewhere. Here, psychoeducation as well as efficacy and safety of the treatment are described. PATIENTS AND METHODS: A total of 99 pediatric ADHD patients were randomized to a 10-week double-blind treatment with atomoxetine (49 patients) or placebo (50 patients). Parents of all patients received four sessions of psychoeducation. Atomoxetine was dosed up to approximately 1.2 mg/kg day (< or = 70 kg) or 80 mg/day (> 70 kg). Improvement of ADHD symptoms was evaluated using the ADHD rating scale (ADHD-RS) and clinical global impression (CGI) rating scales. Safety was assessed based on adverse events (AEs). RESULTS: The study population was predominantly male (80.8%) and diagnosed with the combined ADHD subtype (77.8%). The least square mean (lsmean) change from baseline to endpoint in total ADHD-RS score was -19.0 for atomoxetine patients and -6.3 for placebo patients, resulting in an effect size (ES) of 1.3 at endpoint. Treatment response (reduction in ADHD-RS score of > or = 25 or > or = 40%) was achieved in 71.4 or 63.3% of atomoxetine patients and 28.6 or 14.3% of placebo patients. The lsmean change from baseline to endpoint in CGI-Severity was -1.8 in the atomoxetine group compared with -0.3 in the placebo group. The difference between treatments in CGI-Improvement at endpoint was -1.4 in favor of atomoxetine. No serious AEs occurred. The safety profile of atomoxetine was in line with the current label. CONCLUSIONS: Atomoxetine combined with psychoeducation was superior to placebo and psychoeducation in ADHD core symptoms improvement. The large ES might be a result of including stimulant-naïve patients only, but also may indicate a positive interaction between atomoxetine treatment and psychoeducation, possibly by increased compliance.
