Does OROS-methylphenidate improve core symptoms and deficits in executive function? Results of an open-label trial in adults with attention deficit hyperactivity disorder
Abstract
Objective This pilot, uncontrolled, open-label study evaluated the safety/tolerability and potential effectiveness of OROS-methylphenidate (OROS-MPH) in adult attention deficit hyperactivity disorder (ADHD). Methods Adults with DSM-IV-defined ADHD were enrolled in this 38-day study. Retrospective childhood diagnosis was made using the Wender Utah Rating Scale. Eligible patients required a baseline Conners Adult ADHD Rating Scale (CAARS) score > or = 24, Clinical Global Impression of Severity (CGI-S) score > or = 4 (at least moderate illness), and Montgomery-Asberg Depression Rating Scale (MADRS) score Results Thirty-two patients formed the safety analysis; however, 30 comprised the effectiveness analysis since two patients did not meet diagnostic inclusion criteria. No serious adverse events were reported and there were no early withdrawals due to adverse events. There were no clinically significant changes in endpoint ECGs, physical examination, or blood pressure. Mean pulse rate increased by 5.9 beats/min (p = 0.003) and mean body weight decreased by 2.2 kg at endpoint (p Conclusions This uncontrolled, open-label trial suggests that OROS-MPH is well tolerated, providing core symptom control with the added benefit of improving executive function. However, future larger, randomized, controlled trials are required.

The finding that lisdexamfetamine improves executive function in adult ADHD is similar to previous studies in adults with ADHD treated with psychostimulants such as MPH and nonstimulants such as atomoxetine.
“This finding is similar to previous studies in adults with ADHD treated with psychostimulants, such as MPH,35 and nonstimulants, such as atomoxetine.36”
From Exploratory meta-analysis on lisdexamfetamine versus placebo in adult ADHD (2014) · cites this paper as [35]
The effects seen in the current study on weight and cardiovascular parameters were consistent with those previously reported for stimulants, including LDX, in adults.
“The effects seen in the current study on weight and cardiovascular parameters were consistent with those previously reported for stimulants, including LDX, in adults [7-9,18,37].”

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.
