How does Quillivant XR work to treat ADHD?
Dextroamphetamine-amphetamine, the active ingredient in Quillivant XR, is a central nervous system stimulant. It is believed to work by increasing the levels of certain neurotransmitters, such as dopamine and norepinephrine, in the brain. These neurotransmitters play a role in attention, focus, and impulse control, and their increased availability can help manage ADHD symptoms [4].
What are the potential side effects of dextroamphetamine-amphetamine medications?
Common side effects associated with dextroamphetamine-amphetamine stimulants include decreased appetite, dry mouth, trouble sleeping, weight loss, dizziness, and stomach pain [5]. More serious side effects can include increased blood pressure, rapid heart rate, mood changes, and, in rare cases, circulatory problems [5].
Can children take Quillivant XR for ADHD?
Yes, dextroamphetamine-amphetamine formulations, including extended-release versions like Quillivant XR, are prescribed for children aged 6 years and older to treat ADHD [2, 4]. Dosage and administration are tailored to the individual child's needs.
What is the difference between immediate-release and extended-release amphetamines?
Immediate-release formulations of dextroamphetamine-amphetamine provide a rapid onset of action that typically lasts for several hours. Extended-release (XR) formulations are designed to release the medication gradually over a longer period, providing sustained symptom control throughout the day with fewer daily doses [2, 4].
Are there non-stimulant medications for ADHD?
Yes, non-stimulant medications are also used to treat ADHD. These include atomoxetine (Strattera), guanfacine (Intuniv), and clonidine (Kapvay), among others. They work through different mechanisms than stimulants and may be an option for individuals who do not tolerate stimulants or for whom stimulants are not sufficiently effective [6].
How is dextroamphetamine-amphetamine prescribed and monitored?
Dextroamphetamine-amphetamine medications are prescription-only drugs and are typically prescribed by a physician after a thorough evaluation for ADHD. Treatment involves careful monitoring for efficacy and potential side effects, including regular checks of blood pressure, heart rate, and weight [4, 5].
