How Does It Work?

Methylphenidate ER oral suspension is a stimulant medication. While stimulants can cause hyperactivity, they appear to have a calming effect when used in the doses for ADHD. The exact way methylphenidate ER oral suspension produces a calming effect is unknown. What is known is that the medication affects certain chemical messengers in the brain known as neurotransmitters.
More specifically, methylphenidate ER oral suspension acts on the neurotransmitters dopamine and norepinephrine. Having too little of these neurotransmitters in certain areas of the brain is thought to lead to inattention, hyperactivity, and impulsive behavior -- the core symptoms of ADHD.
Methylphenidate ER oral suspension works by increasing the amount of dopamine and norepinephrine in certain areas of the brain. This increase in dopamine and norepinephrine would be expected to cause hyperactivity and overstimulation; however, in people with ADHD (who may not have enough dopamine and norepinephrine), increasing dopamine and norepinephrine can improve focus and reduce hyperactive and impulsive behaviors.
