Quillivant XR is a once-daily extended-release liquid formulation of methylphenidate, prescribed for the treatment of Attention Deficit Hyperactivity Disorder (ADHD) [1]. It is a central nervous system stimulant that works by increasing the levels of certain natural chemicals in the brain [2].
How does Quillivant XR work for ADHD?
Quillivant XR is a stimulant medication that works by affecting the balance of neurotransmitters, primarily dopamine and norepinephrine, in the brain [3]. By increasing the availability of these neurotransmitters in the spaces between nerve cells, it helps improve attention and focus and reduce impulsivity and hyperactivity, which are characteristic symptoms of ADHD [2][3]. The extended-release formulation allows for a once-daily dosing, providing symptom control throughout the day [1].
What is the active ingredient in Quillivant XR?
The active ingredient in Quillivant XR is methylphenidate [1].
Are there other methylphenidate medications for ADHD?
Yes, there are several other medications containing methylphenidate available for ADHD, including immediate-release and extended-release formulations in various forms such as tablets, capsules, and patches. Examples include Ritalin, Concerta, and Daytrana [4]. Quillivant XR is distinct due to its liquid, extended-release formulation [1].
