Question | Answer |
---|---|
general action of CNS stimulants | increase CNS neurons non-specifically --> global CNS stimulation whereas antidepressants elevate mood WITHOUT CNS global stim |
Classes of drugs that treat ADHD | ampethamines, amphetamine-like, non-stimulant agent |
other classes used to treat ADHD | TCAs, atypical antidepressant - these agents block reuptake of NOR, so have lesser CNS SEs than stimulants |
What are desired CNS effects of stimulants | wakeful/alert/elevate mood reduce fatigue, increase self confidence |
what is MOA of CNS stimulants | promote release of Dopa/Nor. Lesser action in blocking reuptake of Dopa/Nor. |
why do CNS stimulants have huge potential for abuse | strong euphoria combined with tolerance that develops |
SEs related to NOR release/action | increased HR, force, AV conduction --> MI, intracranial bleed, HTN, dysrhth, angina (weight loss) |
SEs related to Dopa release/action | psychosis, hallucinations, delusions, paranoia |
Name 3 CNS stimulants available in short/int/long acting formulas | amphetamine, dextro-amphetamine, meth-amphetamine |
name a CNS stimulant ONLY available in long-action formula | lisdex-amphetamine |
name a drug that has similar MOA of amphetamine in that it helps release Dopa/Nor | methylphenidate |
methylphenidate routes of admin | oral (short, int, long) and now transdermal patch that lasts 9 hours with residual effect 3 hours after removal |
what is a NON-stimulant indicated for ADHD | atomoxetine |
MOA atomoxetine | selective reuptake inhibitor of Nor |
who is atomoxetine indicated for | slow onset, favored for adults. limited studies on kids |
What are SEs of atomoxetine | same as stimulant, but to lesser effect bwo MOA (n/v/somnolence, sleep diff, diz, mood swings, dec appetite, wt loss, growth retardation, inc bp/hr |
what other agens are used for ADHD | TCAs, atypical buproprione |
which drug has lowest CNS SEs | atomoxetine |
what is MOA of atomoxetine | selective reuptake inhibitor Nor |
