Definition
Atomoxetine is a highly selective centrally acting norepinephrine reuptake inhibitor (SNRI), licensed for the treatment of attention-deficit hyperactivity disorder (ADHD) in USA, United Kingdom, and elsewhere. Atomoxetine is a white solid intended for oral administration.
Pharmacological Properties
Pharmacokinetics
Following oral ingestion with or without food, atomoxetine is rapidly absorbed with peak plasma levels occurring at approximately 1–1.5 h (Sauer et al. 2005). With regular dosing, steady-state concentrations are obtained by day 10, with trough plasma concentrations of ~30–40°ng/mL. The metabolism of atomoxetine is dependent primarily on the hepatic cytochrome P450(CP450) system, which is highly polymorphic such that individuals can be classified into extensive metabolizers (EMs) or poor metabolizers...
