Which medication is a non-stimulant used for ADHD?

• A. Methylphenidate
• B. Atomoxetine
• C. Amphetamine
• D. Dextroamphetamine

Answer: (B)

Atomoxetine is the non-stimulant used for ADHD. It works by selectively inhibiting norepinephrine reuptake, which increases norepinephrine activity in the prefrontal cortex to help with attention and behavioral control without producing the rapid, rewarding effects of stimulants. This makes it a good option when stimulants are unsuitable or cause intolerable side effects, or when there are concerns about substance use, tic disorders, or anxiety. It often requires several weeks to achieve full benefit. In contrast, the other commonly used ADHD medications—methylphenidate, amphetamine, and dextroamphetamine—are stimulants that boost dopamine and norepinephrine and tend to have a quicker onset but come with higher potential for abuse and stimulant-related side effects.
