Dexmethylphenidate

Dexmethylphenidate is the more pharmacologically active enantiomer of methylphenidate, classified as a central nervous system stimulant and norepinephrine-dopamine reuptake inhibitor. Approved for medical use in the United States in 2001 and sold under the brand name Focalin, it is primarily prescribed for the treatment of ADHD. It is approximately twice as potent as racemic methylphenidate and is reported to produce cleaner stimulant effects with fewer side effects. It is considered habit-forming.
