What is the mechanism of action of stimulant medications in the treatment of ADHD?

Stimulants = methyphenydate, amphetamine

  • Stimulate portions of the brain that are underactive

  • Increase available dopamine and norepinephrine by blocking reuptake, facilitating release into the synapse

Amphetamine specifically gets into the presynaptic neuron and increases vesicle release

What is the most effective treatment for ADHD?

Medical management

Stimulants are first line

(Atomoxetine, alpha-2 blockers 2nd line)

Helps with sympathetic overdrive, reduction of fight/flight response

Can be used in conjunction of stimulants

May cause sedation, drowsiness, depression, low BP, dizziness, fainting
