Methylphenidate is used to treat patients suffering from either attention deficit hyperactive disorder or narcolepsy.
Attention deficit hyperactivity disorder is a condition suffered by both adults and children wherein they struggle to concentrate for long periods of time and cannot focus on tasks. The condition makes them easily distracted and often impulsive. Using Methylphenidate enables the patient to have an increased ability to concentrate and this helps to decrease restlessness.
Narcolepsy is a condition where the patient has an uncontrolled desire to sleep. By stimulating the central nervous system the use of Methylphenidate can help the patient to stay awake to complete normal tasks.
Methylphenidate acts on the central nervous system as a stimulant. The medication is available by prescription only and comes in a wide range of forms. The medication can be attained in the following brands:
