Methylphenidate

Methylphenidate (Ritalin, MPH) is a psychostimulant drug approved for treatment of attention-deficit hyperactivity disorder, postural orthostatic tachycardia syndrome and narcolepsy. It may also be prescribed for off-label use in treatment-resistant cases of lethargy, depression, neural insult and obesity. Methylphenidate belongs to the piperidine class of compounds and increases the levels of dopamine and norepinephrine in the brain through reuptake inhibition of the monoamine transporters. Methylphenidate possesses structural similarities to amphetamine and its pharmacological effects are more similar to those of cocaine, though MPH is less potent and longer in duration of action.
