Methylphenidate: The Stimulant for ADHD and Narcolepsy
What is Methylphenidate?
Methylphenidate is a stimulant medication primarily used to treat attention deficit hyperactivity disorder (ADHD)and narcolepsy. It works by increasing the levels of dopamine and norepinephrine in the brain, improving focus and reducing hyperactivity.
