Adderall XR 25mg is an extended-release central nervous system (CNS) stimulant used in the treatment of Attention Deficit Hyperactivity Disorder (ADHD) in adults, adolescents, and children aged 6 and older. It contains a combination of amphetamine and dextroamphetamine, which work by increasing the levels of key neurotransmitters—dopamine and norepinephrine—in the brain to enhance attention, focus, and self-control.
