There is very-low- quality evidence that clonidine has a small effect on oppositional behaviour and conduct problems in youth with ADHD , with and without ODD or CD .
There is moderate- quality evidence that guanfacine has a small-to-moderate effect on oppositional behaviour in youth with ADHD , with and without ODD .
There is high- quality evidence that atomoxetine has a small effect on oppositional behaviour in youth with ADHD , with and without ODD or CD .
Conclusions : Evidence indicates that psychostimulants , alpha-2 agonists , and atomoxetine can be beneficial for disruptive and aggressive behaviours in addition to core ADHD symptoms ; however , psychostimulants generally provide the most benefit
Objective : Children with attention-deficit hyperactivity disorder ( ADHD ) may have oppositional behaviour , conduct problems , and aggression .
These symptoms vary in severity , and may be related to a comorbid diagnosis of oppositional defiant disorder ( ODD ) or conduct disorder ( CD ) .
Critical evaluation of the efficacy of ADHD medications may guide the clinician regarding the usefulness of medications for these symptoms .
Double-blind, placebo-controlled trial of clonidine in hyperactive children with mental retardation.
A 12-week , double-blind , r and omized , placebo-controlled trial of oral clonidine in three fixed doses ( 4 , 6 , and 8 mcg/kg/day ) using a crossover design was conducted with 10 children who had hyperkinetic disorder ( mean age 7.6 years + /-.54 ) . All had comorbid mental retardation . Both parents ' ratings on the Parent Symptom Question naire and clinicians ' ratings on the Hillside Behaviour Rating Scale showed a marked dose-related response to clonidine in hyperactivity , impulsivity , and inattention . Drowsiness was a common side effect of clonidine . It wore off by the 2nd to 4th week in most cases . Thus , clonidine is a safe and effective medication in young hyperkinetic children with comorbid mental retardation
