What does Concerta do to the dopamine and norepinephrine?

Concerta, which contains methylphenidate, primarily acts as a central nervous system stimulant by blocking the reuptake of dopamine and norepinephrine in the brain. This increases the availability of these neurotransmitters in the synaptic cleft, enhancing their effects on attention, focus, and impulse control. By elevating dopamine levels, Concerta can help improve symptoms of attention deficit hyperactivity disorder (ADHD), while the increase in norepinephrine contributes to improved alertness and mood regulation.
