Ritalin (methylphenidate hydrochloride) acts as a central nervous system stimulant by blocking the reuptake of dopamine and norepinephrine in the brain . While its exact mechanism is not fully understood, studies show that Ritalin increases the concentrations of dopamine and norepinephrine in the synaptic space, which corrects attention deficits and hyperactivity . The drug’s effects are believed to result from blocking dopamine and norepinephrine transporters, thereby increasing catecholamine tone in the prefrontal cortex—an area of the brain thought to play a prominent role in ADHD pathophysiology . Low therapeutic doses selectively activate NE and DA neurotransmission within the prefrontal cortex, improving clinical efficacy while minimizing side effects such as locomotor-activating effects associated with higher doses . The beneficial effects of Ritalin on sustaining attention are also mediated by alpha-1 adrenergic receptor activity . For patients with ADHD, Ritalin may help increase attention and decrease impulsiveness and hyperactivity .
