How do ADHD agents work?

Attention deficit hyperactivity disorder (ADHD) agents are medications prescribed to manage ADHD symptoms such as lack of attention, hyperactivity, and impulsive behavior. ADHD medications work on the central nervous system to improve concentration and reduce impulsive and hyperactive behaviors.

ADHD medications work in different ways to improve ADHD symptoms. The main types of ADHD medications include:

  • Stimulants: Stimulants increase the levels of two neurohormones (catecholamines) dopamine and norepinephrine in the brain. Catecholamines regulate attention, thinking, pleasure and movement. Increased catecholamine levels enhance brain activity and improve alertness and concentration.
  • Alpha-2 agonists: Alpha-2 agonists stimulate protein molecules known as alpha-2 receptors in the central and sympathetic nervous system, which reduces the release of norepinephrine. Alpha-2 agonists decrease blood pressure, inhibit pain transmission, and have sedative effects which reduce impulsive behavior and hyperactivity.
  • SNRIs: Selective norepinephrine reuptake inhibitors (SNRIs) work similar to stimulants, but increase only norepinephrine levels in the brain by inhibiting their reabsorption (reuptake).
