Abstract

STUDY OBJECTIVES: This study compared the effects of atomoxetine and methylphenidate on the sleep of children with attention-deficit/hyperactivity disorder (ADHD). This study also compared the efficacy of these medications for treating ADHD in these children. DESIGN: Randomized, double-blind, crossover trial. SETTING: Two sleep disorders centers in the United States; 1 in a private-practice setting and 1 in a hospital setting. PATIENTS: 85 children diagnosed with ADHD. INTERVENTIONS: Twice-daily atomoxetine and thrice-daily methylphenidate, each for approximately 7 weeks. MEASUREMENTS AND RESULTS: Relative to baseline, the actigraphy data indicated that methylphenidate increased sleep-onset latency significantly more than did atomoxetine (39.2 vs 12.1 minutes, p < .001). These results were consistent with the polysomnography data. Child diaries indicated that it was easier to get up in the morning, it took less time to fall asleep, and the children slept better with atomoxetine, compared with methylphenidate. Parents reported that it was less difficult getting their children up and getting them ready in the morning and that the children were less irritable, had less difficulty getting ready for bed, and had less difficulty falling asleep with atomoxetine, compared with methylphenidate. There were no significant differences between medications using the main measures of efficacy for ADHD treatment. Atomoxetine was superior on some secondary ADHD treatment-efficacy measures, based on parent reports. The only significant differences in treatment-emergent adverse events were greater incidence of decreased appetite and greater incidence of insomnia with methylphenidate. CONCLUSIONS: Patients receiving twice-daily atomoxetine had shorter sleep-onset latencies, relative to thrice-daily methylphenidate, based on objective actigraphy and polysomnography data. Although both medications decreased nighttime awakenings, the decrease was greater for methylphenidate.

  • A review of scientific studies comparing medicated and unmedicated children describes inconsistent outcomes, both for polysomnographic measures and for parental reports.

    “However, a review of scientific studies comparing medicated and unmedicated children describes inconsistent outcomes, both for polysomnographic measures and for parental reports [123].”
  • In a randomized, double-blind, cross-over study comparing methylphenidate (thrice daily) and atomoxetine (twice daily) in children with ADHD, methylphenidate increased sleep-onset latency significantly more than atomoxetine, based on actigraphic and polysomnographic data.

    “In a randomized, double-blind, cross-over study comparing the effect of methylphenidate (given thrice daily) and atomoxetine (given twice daily) on the sleep of children with ADHD, methylphenidate increased sleep-onset latency significantly more than did atomoxetine, both considering actigraphic and polysomnographic data [123].”
  • In the same study, both medications decreased night-time awakenings, but the decrease was greater for methylphenidate.

    “Both medications decreased night-time awakenings, but the decrease was greater for methylphenidate.”
  • In the same study, both children's diaries and parents' reports indicated better quality of sleep (getting ready in the morning, getting ready for bed, falling asleep) with atomoxetine compared with methylphenidate.

    “Moreover, both childrens’ diaries and parents’ reports indicated a better quality of sleep (in terms of “getting ready in the morning”, “getting ready for bed”, “falling asleep”) with atomoxetine, compared with methylphenidate.”
  • When data on standard deviations were missing, study authors were contacted or data were calculated using standard error of subgroups or confidence intervals.

    “When data on standard deviations were missing, study authors were contacted to provide missing data [18] or it was calculated using the standard error of subgroups or confidence intervals [19-21].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
