ADHD characters
biologic
not moral disorder
behavioral syndrome
involves biochem messengers - DA, NE, E, etc.
methylphenidate
stimulant
dextroamphetamine
stimulant
lisdexamfetaline
stimulant
oral prodrug - converted to d-amphetamine
longer duration
cannot be crushed and injected
stimulant MOA
increased DA
-block reuptake
work to increase DA and NE available
activate inhibitor neurons
amphetamines MOA
block DA reuptake
-displace DA and NE - displacing natural storage vesicles
atomoxetine MOA
NE reuptake inhibitor
unknown mechanism - increased prefrontal cortex DA
methylphenidate NT
increased DA
amphetamine NT
increased NE and DA
atomoxetine NT
increase NE
guanfacine, clonidine MOA
decrease CNS sympathetic outflow
goal of stimulant tx
improve concentration
adverse stimulants
tics
appetite suppression
anemia
sleep disturbance
block DA reuptake
methylphenidate
