Objective: The primary purpose of this study was to examine the cardiovascu
lar effects of Adderall (R) (ADL) in a clinic-based group of youths with at
tention-deficit/hyperactivity disorder ranging in age from 4 to 17 years. M
ethod: One hundred thirty-seven patients were treated with either methylphe
nidate (MPH) or ADL. Youths prescribed MPH were given medication twice dail
y, and youths treated with ADL received medication once daily. Patients wer
e evaluated under five conditions: baseline, placebo, 5 mg/dose, 10 mg/dose
, or 15 mg/dose. Resting pulse, diastolic blood pressure, and systolic bloo
d pressure were examined after 1 week at each treatment condition. Changes
from baseline on these parameters were examined. Results: The short-term ca
rdiovascular effects of both ADL and MPH were modest. No patients experienc
ed any clinically significant change in these cardiovascular measures durin
g the course of this brief trial. Conclusion: Since the short-term cardiova
scular effects of ADL appear minimal, specific cardiovascular monitoring du
ring short-term ADL treatment at doses of 15 mg/day or less does not appear
to be indicated. In addition, under similar conditions, using similar meth
ods, both medication treatments led to changes in blood pressure and pulse
that were clinically insignificant.
