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.
How Methylphenidate Works
