Ritalin (Methylphenidate)
Ritalin is a central nervous system (CNS) stimulant prescription medication indicated for the treatment of Attention Deficit Hyperactivity Disorder (ADHD) and Narcolepsy. It contains the active ingredient methylphenidate hydrochloride and works by modulating natural chemicals in the brain, specifically blocking the reuptake of norepinephrine and dopamine to enhance focus, memory, and impulse control. As a federally regulated Schedule II controlled substance, it must only be obtained and used under strict medical supervision due to a high risk of abuse, misuse, and physical dependence.
