What is Dexmethylphenidate ER?
Dexmethylphenidate ER is a central nervous system (CNS) stimulant medication commonly prescribed for the treatment of Attention Deficit Hyperactivity Disorder (ADHD) in children and adults. It is the extended-release form of dexmethylphenidate, meaning it releases gradually throughout the day for long-lasting symptom control.
This medication is also known by its brand name Focalin XR and is a refined version of methylphenidate, designed to improve focus, attention span, and impulse control.
How Does Dexmethylphenidate ER Work?
Dexmethylphenidate ER works by increasing the activity of two important brain chemicals:
