METHYLPHENIDATE

is a stimulating drug which is related to the amphetamine family of drugs, with a complementary mechanism of action. It blocks the reuptake of catecholamines in the synaptic cleft between synapses whilst stimulating the presynaptic release of catecholamines. Unlikely amphetamines, methylphenidate is a better reuptake blocker than it is in its releasing agent role. Methylphenidate is currently used in the treatments of hyperactivity disorders and narcolepsy. It is currently a controlled substance in the U.S. due to the probability of becoming addicted to taking it.
