Everything You Need to Know About Methylphenidate (Ritalin, Concerta)
Methylphenidate, commonly known by its brand names Ritalin و Concerta, is a central nervous system (CNS) stimulant primarily used to treat Attention Deficit Hyperactivity Disorder (ADHD). It’s also prescribed for narcolepsy and certain cases of treatment-resistant اكتئاب. Let’s break down what methylphenidate is, how it works, and what you need to know before taking it.
What is Methylphenidate?

Methylphenidate works by:
- Increasing dopamine and norepinephrine levels: These are brain chemicals that play a key role in attention and focus.
