Atomoxet 25 mg contains atomoxetine, a selective norepinephrine reuptake inhibitor (SNRI) that works by increasing the levels of norepinephrine in the brain. This neurotransmitter plays a crucial role in regulating attention, focus, and impulse control, making Atomoxet 25 mg an effective treatment for ADHD. Unlike stimulant medications, Atomoxet 25 mg does not carry the risk of abuse or dependence, making it a safer option for long-term use.
