How do selective norepinephrine reuptake inhibitors work?

Selective norepinephrine reuptake inhibitors are medications prescribed to manage symptoms of attention deficit hyperactivity disorder (ADHD), such as lack of attention, impulsive behavior, and hyperactivity. Selective norepinephrine reuptake inhibitors work by increasing the level of norepinephrine in the brain.

Norepinephrine is one of the chemicals (neurotransmitters) in the brain that plays a role in regulating attention and mood. Nerve cells (neurons) communicate with each other by transmitting signals through neurotransmitters, which bind to protein molecules (receptors) on cell surfaces and initiate action.

Selective norepinephrine reuptake inhibitors increase the level of norepinephrine by inhibiting its reabsorption (reuptake), a natural process in the brain after neurotransmission is over. An increase in norepinephrine levels is found to improve ADHD symptoms in children.

A selective norepinephrine reuptake inhibitor, viloxazine, has been approved by the FDA in April 2021, to treat ADHD. Viloxazine was historically believed to modulate norepinephrine activity, however, later studies have demonstrated that it also modulates the activity of serotonin, an important neurotransmitter involved in mood regulation.

How are selective norepinephrine reuptake inhibitors used?

Selective norepinephrine reuptake inhibitors are capsules approved by the FDA for treating attention deficit hyperactivity disorder in children aged 6 to 17 years. The medication is under clinical trials for efficacy and safety in adults and not yet approved for use by adults.
