Analog Classroom Assessment of Adderall® in Children With ADHD
Open accessAbstract
OBJECTIVE: This was a randomized, double-blind, crossover study of 30 children with attention-deficit/hyperactivity disorder (ADHD) that evaluated the time course effects of four doses of Adderall (5, 10, 15, and 20 mg), an inactive control (placebo), and a positive control (clinical dose of methylphenidate). METHOD: For each treatment condition, a capsule was administered in the morning and assessments were performed in an analog classroom setting every 1.5 hours across the day. Subjective (teacher ratings of deportment and attention) and objective (scores on math tests) measures were obtained for each classroom session, and these measures were used to evaluate time-response and dose response effects of Adderall. RESULTS: For doses of Adderall greater than 5 mg, significant time course effects were observed. Rapid improvements on teacher ratings and math performance were observed by 1.5 hours after administration, and these effects dissipated by the end of the day. The specific pattern of time course effects depended on dose: the time of peak effects and the duration of action increased with dose of Adderall. CONCLUSIONS: This documentation of efficacy in a controlled study supports the addition of Adderall to the armamentarium of psychotropic medications for the treatment of ADHD. The differences in time-response patterns of Adderall and methylphenidate may help tailor treatment to meet specific clinical needs of different children with ADHD.

There is a paucity of studies on the pharmacokinetic and behavioral time course of effects of low-dose amphetamine administration for ADHD.
“In spite of the frequency of use of amphetamine-containing products for the treatment of ADHD, there is a surprising paucity of studies on the pharmacokinetic (PK) and behavioral time course of effects of low-dose amphetamine administration for ADHD (Brown et al., 1979(Brown et al., , 1980;;Pelham et al., 1999;Swanson et al., 1998).”

Swanson et al. (1998) demonstrated a pattern of deterioration on placebo in performance across morning into afternoon assessments.
“It is interesting that the Swanson et al. (1998) report also demonstrated the pattern of deterioration on placebo in performance across morning into afternoon assessments, highlighting the importance of providing appropriate control groups for time-response studies.”

A previous analog classroom pharmacodynamic study of Adderall documented behavioral effects up to approximately 5 to 7 hours postdose for the highest dose condition (5 to 20 mg).
“A previous analog classroom pharmacodynamic study of Adderall documented the time course of behavioral and classroom performance effects across a dose range of 5 to 20 mg given once, with behavioral effects evident up to approximately 5 to 7 hours postdose for the highest dose condition (Swanson et al., 1998).”

Adderall XR showed excellent efficacy and tolerability and displayed a time course of action that extended beyond that of immediate-release Adderall at the 10-mg q.d. dose used as a positive control, and by comparison to prior reports of the pharmacodynamic time course for Adderall as assessed by similar measures, even for doses as high as 20 mg q.a.m.
“Overall, Adderall XR showed excellent efficacy and tolerability and displayed a time course of action that extended beyond that of immediate-release Adderall at the 10-mg q.d.dose used as a positive control in this study, and by comparison to prior reports of the pharmacodynamic time course for Adderall as assessed by similar measures (Swanson et al., 1998), even for doses as high as 20 mg q.a.m.”

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.
