Dextroamphetamine is a potent central nervous system (CNS) stimulant and a member of the amphetamine family. It is commonly prescribed for the treatment of Attention Deficit Hyperactivity Disorder (ADHD) and narcolepsy. It works by increasing the levels of certain neurotransmitters in the brain, such as dopamine and norepinephrine, which help improve focus, attention, and energy levels.
