Adderall is a prescription medication that contains a combination of amphetamine and dextroamphetamine. It belongs to a class of drugs called central nervous system stimulants, and it is primarily used to treat attention deficit hyperactivity disorder (ADHD) and narcolepsy.

In individuals with ADHD, Adderall can help improve attention span, concentration, and impulse control. It works by increasing the levels of certain neurotransmitters, such as dopamine and norepinephrine, in the brain, which play a role in regulating attention and behavior.
