Generic Name: Atomoxetine

Brand Name: Strattera

What is Strattera?

Strattera (atomoxetine) is known to affect the chemicals present in the brain including the nerves that are said to contribute to impulsivity and hyperactivity. This medication is mostly used as a treatment option for those with ADHD or attention deficit hyperactivity disorder. It is basically made as part of the complete treatment plan, which also includes social, psychological, and other forms of treatment.

This medication is known to stop and improve certain ADHD symptoms. It increases concentration, ensures that the individual stays focused, increases the ability of the individual to pay attention to detail in particular tasks, and help individuals fight the habit of fidgeting.

Strattera is advertised as the first nonstimulant drug for the treatment of ADHD symptoms. There are various nonstimulants available such as tricyclic antidepressants or Intuniv (guanfacine), which can also be prescribed for ADHD symptoms.

The doctor can also prescribe Strattera for other medical purposes not mentioned above.

How Strattera Works

Strattera is a selective norepinephrine reuptake inhibitor (SNRI). This drug works by strengthening the chemical signals between the nerves that use norepinephrine when sending messages. Although most SNRIs are prescribed for the treatment of depression, Strattera is specifically used for ADHD.

Norepinephrine generally affects an individual’s overall mood. Strattera can change how the brain absorbs norepinephrine and how this chemical acts in the body. 

Strattera is approved for use in children 6 years old and above, teens with ADHD, and adults. The drug's safety has not been established yet for those who are less than 6 years old.
