What is Atomoxetine?

It is available under the brand name Strattera, a selective norepinephrine reuptake inhibitor not classified as a stimulant. Stimulants such as Modafinil and Armodafinil (Artvigil) are drugs that increase the activity of the central nervous system along with producing euphoric effects and having a high addiction potential. SNRIs are a group of drugs that increase the level of serotonin and nor-epinephrine but have negligible addiction potential because of which they are approved for medical use.

What is Atomoxetine used for?

It is primarily used in the treatment of ADHD (Attention Deficit Hyperactivity Disorder), a chronic condition resulting in attention difficulties, hyperactivity, and impulsiveness. It is preferred for the above problem because of the relatively low abuse potential associated with its use. Atomoxetine can be used on its own or in combination with other prescription stimulants. Off-label, it is used in the treatment of mood disorders, eating disorders, cognitive dysfunction, and addictions.

What is the mechanism of action?

It primarily works by inhibiting the reuptake or re-absorption of norepinephrine and dopamine back into the system. Norepinephrine, or noradrenaline, is a hormone and neurotransmitter located in the CNS that plays an important role in a person’s mood and ability to concentrate. Dopamine is responsible for the alertness and arousal functions of people. Increased extracellular levels of either neurotransmitter result from inhibition of their reuptake, which aids in the management of ADHD and other symptoms.
