Products
Atomoxetine is commercially available in capsule form and as a drinkable solution (Strattera, generics). It was approved in many countries in 2009.
Structure and properties
Atomoxetine (C17H21NO, Mr = 255.4 g/mol) is present in drugs as atomoxetine hydrochloride. It is structurally closely related to the SSRI fluoxetine (Fluctine, Prozac, generics), which was also developed at Lilly.
Effects
Atomoxetine (ATC N06BA09) produces significant improvement in the core symptoms of impulsivity, hyperactivity, and attention deficit in ADHD. The effects are due to selective inhibition of the presynaptic norepinephrine transporter NET. This increases norepinephrine concentrations in the central nervous system. The mean half-life is 3.6 hours.
Indications
For the treatment of attention deficit hyperactivity disorder (ADHD).
Dosage
According to the drug label. The capsules and drinking solution are usually taken once daily in the morning and independently of meals.
Abuse
Atomoxetine, unlike methylphenidate, is not an amphetamine derivative and has no euphoric or stimulant effects. Abuse is therefore unlikely.
Contraindications

- Pheochromocytoma
- Severe cardiovascular disease
