Dexamphetamine and methylphenidate elicited comparable, significant improvements in ADHD symptoms in stimulant-naive children and adolescents over 12 months, with greater weight loss on dexamphetamine at 3 months.
HealthDay News — For children and adolescents with attention-deficit/hyperactivity disorder (ADHD), comparable, significant symptom improvement is seen with dexamphetamine and methylphenidate, but weight loss is greater with dexamphetamine at three months, according to a study published online July 7 in the Journal of Paediatrics and Child Health
Alison Poulton, M.D., from The University of Sydney, and colleagues conducted an open-label study involving 100 stimulant-naive children and adolescents with ADHD. Participants were randomly assigned to receive dexamphetamine or methylphenidate and followed for 12 months
The researchers found that at all time periods, there were significant ADHD symptom improvements on either medication, with no significant difference seen between the groups. Sixty-two of the participants remained on their allocated medication at 12 months, with no significant difference between methylphenidate and dexamphetamine (68 versus 56 percent). Weight loss was seen in association with both medications, with greater weight loss on dexamphetamine at three months (−1.44 versus −0.31 kg).
“Both medications worked equally well for improving ADHD symptoms, and a year later most children were still taking their original stimulant, suggesting a comparable level of satisfaction with either medication,” Poulton said in a statement. “The main difference was that children taking dexamphetamine experienced greater weight loss, which is an important consideration when choosing treatment and monitoring growth.”
