Atomoxetina Introduction

Atomoxetina is an active drug ingredient used to treat Attention-Deficit/Hyperactivity Disorder (ADHD) and is also used to treat major depressive disorder (MDD). It was first approved for use in 2002 and is classified as a selective norepinephrine reuptake inhibitor (SNRI). It is marketed under the brand name Strattera.

Uses for Atomoxetina

Atomoxetina is used to treat Attention Deficit/Hyperactivity Disorder (ADHD) in both children and adults. It is also used off-label to treat major depressive disorder (MDD) in adults.

Mechanism of Action

Atomoxetina inhibits the presynaptic reuptake of norepinephrine, resulting in increased extracellular concentrations of norepinephrine. In areas of the brain that control attention and impulsivity, this increased norepinephrine availability can improve cognitive control and lead to reduced symptoms of ADHD.

How Long Does it Take to Work?

The therapeutic effect of Atomoxetina can usually be felt within the first week of treatment, though depending on the patient’s individual response, it may take up to 4 weeks before the full effects are seen.

Absorption

Atomoxetina is rapidly and extensively absorbed after oral administration, with peak plasma concentrations being reached within 1.5 to 2 hours. It is highly bound to plasma proteins.

Route of Elimination

Atomoxetina is mainly eliminated through hepatic metabolism via the cytochrome P450 (CYP) 2D6 isoenzyme. The remainder is eliminated as unchanged drug in the urine and in the feces. The terminal elimination half-life is about 5 hours.

Dosage

Dosage of Atomoxetina will depend on the patient and their condition. Generally, the recommended starting dose for adults is 40mg per day, taken in the morning or evening.
