Strattera (atomoxetine) is a selective norepinephrine reuptake inhibitor (SNRI) approved for ADHD treatment. Unlike stimulants that affect dopamine, Strattera works by increasing norepinephrine levels in the brain. E-Mycin is an antibiotic, Effient is an antiplatelet drug, and Humatrope is a growth hormone - none are used for ADHD.
