Description: Dexmethylphenidate (also known as d-threo-methylphenidate (D-TMP), is the dextrorotatory enantiomer of methylphenidate. It is a norepinephrine-dopamine reuptake inhibitor (NDRI) and releasing agent and thus a psychostimulant, which affects the CNS. Dexmethylphenidate is sold as Focalin by Novartis, as Attenade by Celgene and as a generic drug by Teva. Dexmethylphenidate is currently tested in the treatment of fatigue and nervous system side effects caused by chemotherapy. (Source: http://en.wikipedia.org/wiki/Dexmethylphenidate).

Dexmethylphenidate (trade name Focalin, Novartis, generic by Teva also available), otherwise known as d-threo-methylphenidate (D-TMP), is the dextrorotatory enantiomer of methylphenidate. It is a norepinephrine-dopamine reuptake inhibitor (NDRI) and thus a psychostimulant, which affects the CNS.
Dexmethylphenidate is used as a treatment for ADHD, ideally in conjunction with psychological, educational, behavioral or other forms of treatment. It is proposed that stimulants help ameliorate the symptoms of ADHD by making it easier for the user to concentrate, avoid distraction, and control behavior. Dexmethylphenidate may also improve listening skills and organization of tasks, and may help prevent tic disorders. Because it is a psychostimulant, dexmethylphenidate may also help with narcolepsy and in certain cases of major depression. Although its has many beneficial effects, because it is a stimulant there is a considerable chance for abuse of the drug and intake should be closely monitored by you and your doctor. Importantly, the propensity for "abuse" with d-TMP is much less than for the corresponding racemic product.
