Study Summary
🔬
What They Studied
The research aimed to compare the effects of different doses of long-acting extended-release dexmethylphenidate and mixed amphetamine salts on ADHD symptoms and related side effects.
💡
What They Found
The study found that higher doses significantly reduced ADHD symptoms but also increased side effects such as decreased appetite and insomnia.
📚
What This Means
These findings indicate that while higher doses of both medications improve ADHD symptoms, they also come with more side effects, aligning with the current understanding that dosage plays a crucial role in the effectiveness and tolerability of these medications.
Study Summary
Study Overview
The study aimed to compare the effectiveness of two long-acting stimulant medications for treating ADHD. Researchers wanted to see how these medications affected both ADHD symptoms and overall functioning in children.
The findings suggest that both medications can quickly reduce symptoms, but the impact of the dose level plays an important role in determining the best treatment approach.

Abstract: background
To compare the dose effects of long-acting extended-release dexmethylphenidate (ER d-MPH) and ER mixed amphetamine salts (ER MAS) on attention-deficit/hyperactivity disorder (ADHD) symptom dimensions, global and specific impairments, and common adver...more
Effectiveness Comparison
"The majority of children responded similarly to both stimulant formulations, suggesting that at the group level, treatment with either ER MAS or ER d-MPH resulted in rapid reductions in ADHD symptoms and improvements in both global and many specific domains of impairment."
Importance of Dose Titration
"Our study findings support the importance of individually titrating to optimal efficacy and tolerability, consistent with virtually all treatment algorithms to try a different class of ADHD medication when the first medication selected fails."
Personalized Treatment
"Future comparative effectiveness studies with multiple informants and larger samples over longer time periods are necessary to develop a data-driven, personalized approach to ADHD treatment."
Study Summary
Methods
The study included 56 children and adolescents diagnosed with ADHD who participated in an 8-week trial. This trial used a double-blind, crossover design, meaning neither the participants nor the researchers knew which medication was being taken at any time.
Participants were given different doses of either ER d-MPH or ER MAS, with a randomized placebo week included. The effectiveness of each medication was assessed using several scales, including the ADHD Rating Scale-IV and the Clinical Global Impressions scales, while side effects were tracked with a parent-completed rating scale.

Abstract: methods
Fifty-six children and adolescents with ADHD participated in an 8-week, double-blind, crossover study comparing ER d-MPH (10, 20, 25-30 mg) and ER MAS (10, 20, 25-30) with a week of randomized placebo within each drug period. Efficacy was assessed wi...more
Study Summary
Results
Both medications led to significant improvements in ADHD symptoms, with higher doses showing stronger effects. The study found that total ADHD and hyperactivity symptoms improved notably with higher doses, while inattentive symptoms showed moderate improvement.
However, higher doses were also linked to side effects like decreased appetite and insomnia. Interestingly, nearly half of the participants responded better to one medication over the other, suggesting that individual responses to ADHD medication can vary significantly.

Abstract: results
Both ER d-MPH and ER MAS were associated with significant reductions in ADHD symptoms. Improvement in Total ADHD and Hyperactivity/Impulsivity symptoms were strongly associated with increasing dose, whereas improvements in Inattentive symptoms were o...more
Study Summary
Conclusions
The study concluded that the dose of the medication, rather than the type of stimulant, played a more crucial role in how well it managed ADHD symptoms. This finding underscores the importance of dose adjustments when treating ADHD in children and adolescents.
Abstract: conclusions
Dose level, rather than stimulant class, was strongly related to medication response.
Background Information
Patient Guide
🧬
Extended-release Adderall mechanism
Adderall increases dopamine and norepinephrine in the brain, improving attention and reducing impulsivity in ADHD patients.
⚠️
Dose-dependent side effects
Higher doses of stimulant medications, including Adderall, can lead to common adverse effects like decreased appetite and insomnia.
📉
Growth suppression concerns
Children on stimulants like Adderall may experience reduced growth, including slower height and weight gain, at higher doses.

Expert Opinion: Comparative effectiveness of dexmethylphenidate and amphetamine salts
The findings align with the understanding that stimulant medications significantly reduce ADHD symptoms, with an established effect size of around 1.0, affirming their effectiveness in clinical use.
The adverse effects noted in the study, such as appetite loss and sleep disturbances, are consistent with the common short-term side effects associated with these medications.
Interestingly, individual responses to methylphenidate versus amphetamine can vary widely, as approximately 40% of individuals respond to only one of the medication types.
This idiosyncratic response pattern highlights the importance of personalized treatment plans in managing ADHD effectively.
Moreover, combining behavioral therapy with medication appears beneficial, especially for pre-adolescent children, enhancing overall treatment efficacy.
