Methylphenidate is a central nervous system (CNS) stimulant medication. It is primarily prescribed for the treatment of attention deficit hyperactivity disorder (ADHD) in children and adults, and for narcolepsy. It works by affecting certain neurotransmitters in the brain, which can help improve focus, reduce impulsivity, and manage excessive daytime sleepiness.
Methylphenidate is available in various formulations, including immediate-release (e.g., Ritalin) and extended-release (e.g., Concerta) preparations, which allow for different durations of action and dosing schedules. As a controlled substance, its use requires a prescription and close monitoring by a healthcare professional.
