A Randomized, Placebo-Controlled Trial of Three Fixed Dosages of Prolonged-Release OROS Methylphenidate in Adults with Attention-Deficit/Hyperactivity Disorder
Open accessAbstract
Background There is increasing recognition of attention-deficit/hyperactivity disorder (ADHD) in adults and the need to evaluate efficacy and safety of methylphenidate treatment in these patients.Methods In this double-blind trial, 401 adults with ADHD (218 men; 18-63 years) were randomly assigned to receive prolonged-release osmotic release oral system (OROS) methylphenidate (18 mg, 36 mg, or 72 mg/day) or placebo for 5 weeks. Primary outcome was change in total score on Conners' Adult ADHD Rating Scale (CAARS: investigator-rated) at end point compared with baseline. Adverse events, vital signs, and laboratory parameters were assessed.Results Treatment with 18-mg, 36-mg, and 72-mg/day prolonged-release methylphenidate, compared with placebo, was associated with significantly larger improvement in CAARS total symptom score from baseline to end point than placebo: mean change -10.6 (p = .01), -11.5 (p = .01), and -13.7 (p < .001) versus -7.6, respectively. Responders (> or = 30% decrease) were 50.5%, 48.5%, and 59.6% versus 27.4% (p < .001). Other efficacy measures also showed improvements. Incidence of adverse events was 75%, 76%, and 82% in 18-mg, 36-mg, and 72-mg/day groups, respectively, and 66% in placebo; most frequent included decreased appetite (25% methylphenidate; 7% placebo) and headache (21% methylphenidate; 18% placebo). In methylphenidate-treated patients, 4.3% discontinued due to adverse event; one serious adverse event was possibly related to study drug. Blood pressure and pulse increased at week 1 and then remained stable through week 5.Conclusions Prolonged-release methylphenidate is an effective treatment of ADHD in adults, with a safety profile consistent with methylphenidate use in pediatrics.

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.
