Brief summary
Children and adolescents with Attention Deficit Hyperactivity Disorder (ADHD) who are not tolerating or not responding well to stimulant therapy will be included in this study. Two different strategies for transition from Stimulant to Atomoxetine will be used: Slow (10 weeks) and fast (2 weeks). Changes in ADHD symptoms and tolerability of medication will be compared between the two different switching approaches.
Detailed description
Study B4Z-EW-LYFJ is a phase IV multicentre, open label, controlled study in approximately 120 patients with ADHD from 6 years to 16 years of age. After the screening period, patients will be randomized (centrally in a 1:1 ratio) either to a transition period of 10 weeks (slow switching arm) or to a transition period of 2 weeks (fast switching arm). After completion of the 10 week open phase patients will be treated for a further 4 weeks with atomoxetine.

Individual item scores range from 0 (none/never or rarely) to 3 (severe/very often). Total scores range from 0 to 54. Higher score indicates greater severity of disease. Least squares means are adjusted for baseline, site, treatment, visit and treatment by visit interaction. |
