methylphenidate patch

Methylphenidate is a medication used for treating attention deficit hyperactivity disorder (ADHD). It stimulates the central nervous system (CNS or brain) in a manner that is similar to amphetamines; however, its actions are milder than amphetamines. Amphetamines stimulate the brain by increasing the level of neurotransmitters, dopamine and norepinephrine, in the brain (neurotransmitters are chemicals produced by nerves that are released and attach to other nearby nerves as a means of communication among nerves). The exact mechanism of action of the drug in people with ADHD is unknown. Methylphenidate is the active ingredient in methylphenidate (Ritalin, Concerta), and also is available as pills and liquids. The FDA approved Methylphenidate patches in April 2006.

Use of methylphenidate and MAO inhibitors should be separated by at least 14 days.
