Adderall is a commonly p rescribed medication for the treatment of attention deficit hyperactivity disorder (ADHD) and narcolepsy. It is a combination of two stimulant drugs, amphetamine and dextroamphetamine, which work by increasing the levels of dopamine and norepinephrine in the brain. This helps to improve focus, attention, and impulse control in individuals with ADHD. Adderall XR 20mg is a long-acting version of the medication, which means that it provides sustained release of the active ingredients throughout the day, allowing for better symptom management.
