Ritalin (Methylphenidate) – ADHD Stimulant Medication (Rx, Controlled Substance)
Ritalin (methylphenidate) is a central nervous system (CNS) stimulant used primarily for the treatment of attention deficit hyperactivity disorder (ADHD) and narcolepsy.
It works by blocking the reuptake of dopamine and norepinephrine in the brain, increasing their availability. This helps improve:
- Focus and attention
- Impulse control
- Wakefulness in narcolepsy
Ritalin is considered a first-line ADHD medication in many treatment guidelines, especially for short-acting or immediate symptom control.
