Pharmacogenetic Study of Methylphenidate in Attention Deficit/Hyperactivity Disorder(ADHD) (NETADHD)

October 4, 2011 updated by: Hallym University Medical Center

Association Between Norepinephrine Transporter Polymorphism and Response of Methylphenidate

The noradrenergic system plays a known role in attentional systems and suspected causal role in attention deficit/hyperactivity disorder(ADHD).Methylphenidate also has been suspected as a inhibitor of norepinephrine transporter(SLC6A2). The investigators hypothesis is that norepinephrine transporter polymorphism is associated with responses and adverse effects of OROS-methylphenidate in treatment of ADHD.
