Abstract

Background The objective of this study was to evaluate the safety and efficacy of once-daily OROS methylphenidate (MPH) in the treatment of adults with DSM-IV attention-deficit/hyperactivity disorder (ADHD). Methods We conducted a randomized, 6-week, placebo-controlled, parallel-design study of OROS MPH in 141 adult subjects with DSM-IV ADHD, using standardized instruments for diagnosis. OROS MPH or placebo was initiated at 36 mg/day and titrated to optimal response, depending on efficacy and tolerability, up to 1.3 mg/kg/day. Results Treatment with OROS MPH was associated with clinically and statistically significant reductions in DSM-IV symptoms of inattention and hyperactivity/impulsivity relative to subjects treated with placebo. At endpoint, 66% of subjects (n = 44) receiving OROS MPH and 39% of subjects (n = 29) [corrected] receiving placebo attained our a priori definition of response of much or very much improved on the Clinical Global Impression-Improvement scale plus a >30% reduction in Adult ADHD Investigator System Report Scale score. OROS MPH was associated with small but statistically significant increases in systolic blood pressure (3.5 +/- 11.8 mm Hg), diastolic blood pressure (4.0 +/- 8.5 mm Hg), and heart rate (4.5 +/- 10.5 bpm). Conclusions These results show that treatment with OROS MPH in daily doses of up to 1.3 mg/kg/day was effective in the treatment of adults with ADHD. Because of the potential for increases in blood pressure and heart rate, subjects receiving treatment with MPH should be monitored for changes in blood pressure parameters during treatment.

  • Stimulants are effective in about 70% of patients with ADHD in controlled studies, depending on the study design and maximum drug dosage.

    “Stimulants are effective in about 70% of patients with ADHD in controlled studies [265-267] depending on the study design and maximum drug dosage.”
  • In the United States, more than ten different stimulant preparations have been developed for treatment of ADHD, the most recent being long acting formulations of oros-methylphenidate, mixed amphetamine salts, dexmethylphenidate and lis-dexamphetamine.

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.
