What is methylphenidate patch, and how does it work (mechanism of action)?
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.
