What exactly is Methylphenidate?

As you may remember, a child or adult with ADHD has difficulty paying attention, staying focused, and doing things at once. So what this drug does is stimulate their brain, improve their attention, and help them control their impulsive behavior.
Also, this medicine is used for a condition called narcolepsy, which is a condition in which you fall asleep at any time. Because it helps keep the body and mind awake. These belong to the group of drugs called stimulants. In our country, this medicine is available under various brand names like Concerta, Ritalin SR.
