Researchers wanted to see whether venlafaxine, a medication approved for anxiety and depression, could reduce ADHD symptoms in children and adolescents.
The primary purpose of this study was to describe tolerability and efficacy of venlafaxine in the treatment of children and adolescents with attention deficit hyperactivity disorder (ADHD).
They ran a small clinical trial on 13 children with ADHD. All the children received venlafaxine and were tested before and after treatment.
A 6-week open trial of venlafaxine was conducted in 13 children and adolescents (mean age 9.9 +/- 2.5 years) with ADHD, and without comorbid depression. Venlafaxine was initiated at a dose of 18.75 mg/day and flexibly titrated to 56.25 mg/day. The Conners parent scale and Clinical Global...
Researchers found that the children in the study experienced improvements in their ADHD symptoms after the treatment.
There was also evidence that their overall mental health was better as well.
There were some side effects, but most disappeared after two weeks.
Of note, the researchers did not use a control group as a comparison, which limits the usefulness of the data they gathered.
All subjects completed the trial. Mean final dose of venlafaxine was 40.3 +/- 7.0. Venlafaxine was significantly effective in reducing the total score of the Conners parent scale from baseline to endpoint (P < 0.002, Z =-3.113) and the CGI severity item (P < 0.05). Transient side-effects...
This study provides weak evidence that venlafaxine may help reduce ADHD symptoms in children. However, without a control group, itβs impossible to know with certainty whether the effect seen in the study was due to the medication or the placebo effect.
Other studies have found evidence that venlafaxine may reduce ADHD symptoms, though more research is needed to confirm the findings.
One theory suggested by the authors regarding the mechanism of venlafaxine in ADHD is that venlafaxine may reduce ADHD symptoms by increasing noradrenaline in the brain:
These preliminary data suggest that venlafaxine may be an effective medication in the treatment of some children and adolescents with ADHD. Future double-blind controlled trials should be undertaken.
