Which drug is a non-stimulant option for ADHD?

• A. Atomoxetine
• B. Methylphenidate
• C. Modafinil
• D. Caffeine

Answer: (A)

The main concept is recognizing a non-stimulant option for ADHD pharmacotherapy. Atomoxetine fits this goal because it works differently from stimulants: it selectively inhibits norepinephrine reuptake, increasing norepinephrine in the brain without the rapid dopamine surge that characterizes stimulant medications. This makes it a non-stimulant choice, often used when stimulants aren’t suitable due to issues like tic disorders, anxiety, substance-use concerns, or intolerable stimulant side effects. It tends to take several weeks to produce noticeable benefits and can have side effects such as stomach upset, decreased appetite, and possible increases in blood pressure or heart rate; rare liver injury is also noted.

Methylphenidate is a classic stimulant, boosting dopamine and norepinephrine quickly and typically producing rapid symptom relief. Modafinil is a wakefulness-promoting agent not routinely used as a standard ADHD medication, and caffeine is a general stimulant not an approved ADHD treatment.
