ADHD Flashcards
What are risk/prognostic factors of ADHD?
- males»_space; females
- whites»_space; blacks > hispanics
- 1st degree relative w/ ADHD
- minor physical anomalies (hypertelorism, highly arched palate, low set ears)
-motor delays/neurological soft signs - very low birthweight
What are some patho features of ADHD?
- decreased total brain volume
- decreased activity
- lack of connectivity
- default mode = network overactivity
What are the main ADHD symptoms?
- inattention
- hyperactivity
- impulsivity
What are the general requirements to diagnosis ADHD?
- symptom onset BEFORE 12 yo
- significant impairment in 2 or more settings with documented symptoms
- symptoms interfere with or dec quality of social, academic or occupational functioning
- 6 or more symptoms for at least 6 months (if 17 or older only need 5 symptoms)
What is the general treatment algorithm for a patient with predominant ADHD?
- stimulant —– MPH or AMP
(try both before 2nd line) - atomoxetine, viloxazine, guanfacine ER, clonidine ER, bupropion
(1st line if pt has active SUD) - combo therapy or TCA
What is the general treatment algorithm for ADHD in a patient with predominant Tourette’s?
- dopamine antagonist or alpha agonist
- haloperidol, risperidone, aripiprazole
- clonidine or guanfacine
if some response….
- ADD stimulant, atomoxetine or alpha agonist
if still inadequate….
- try alternative dopamine antagonist or alpha agonist
What is the general treatment algorithm for ADHD in a patient with predominant bipolar/severe aggression?
- atypical antipsychotic, lithium, or anticonvulsants
(mood stabilizers)
If some response…
- ADD stimulant
if still inadequate…
- try alternative or additional mood stabilizer
What is the general treatment algorithm for ADHD in a patient with predominant anxiety/depression?
- antidepressant
If some response…
- ADD stimulant
if still inadequate…
- try alternative antidepressant
What adjustment should be made when moving from AMP to MPH?
increase dose
What adjustment should be made when moving from MPH to AMP?
decrease dose
Which is more potent? AMP or MPH?
AMP!
What needs to be monitored at baseline and then every 3 months on stimulant therapy?
height, weight appetite and sleeping patterns
What ADR are common for stimulants?
- psychiatric
- cardiac (inc BP & HR)
- growth inhibition
- reduced appetite/weight loss
- insomnia
How are psychiatric ADR of stimulants managed?
decrease dose or D/C
+ supportive therapy
T or F: A contraindication to stimulant use is cardiac issues.
FALSE, cardiac issues are NOT CI for stimulant use
How is the growth inhibition ADR of stimulants managed?
yearly drug free trials (i.e. no stimulants over school breaks)
How is the reduced appetite/weight loss ADR of stimulants managed?
eating high fat meals when stimulant effect is low (fat will delay abs, keep consistent)
ADD cyprohepatdine QHS
How is the insomnia ADR of stimulants managed?
give dose earlier
lower last dose of day/give it earlier
ADD sedating medication QHS
(guanfacine, clonidine, melatonin, cyproheptadine)
What agents increase MPH absorption and decrease the delayed effect of ER formulations?
antacids, PPIs, H2RAs
What agent decreases the excretion of AMP?
antacids
What agent increases the absorption of AMP?
PPIs
What agent decreases the absorption of AMP?
acidic agents
What stimulant has a DDI with CYP2D6 inhibitors (i.e. some psych agents)/what happens?
Which stimulant is preferred in patients on concurrent psych agents?
increases exposure of mixed AMP salts
MPH is preferred
What is the issue with alcohol when using stimulants?
alcohol can cause stimulant dumping
What does adjustment is needed when going from Dex-MPH to MPH?
What about MPH to Dex-MPH?
Which is more potent?
double the dose
half the dose
Dex-MPH is 2x more potent
What stimulant is preferred & first line in children?
MPH!
What stimulant is FDA approved in children?
AMP!
Which MPH products are 30% IR/70% ER?
- MPH ER (Metadate ER, Quillivant XR)
- MPH ER chew (Quillichew)
- MPH CD (Metadate CD)
Which MPH products are 50% IR/50% ER?
- MPH LA (Ritalin LA)
- Dex-MPH ER (Focalin XR)
Which MPH extended release product is preferred in patients with severe AM symptoms?
50% IR/50% ER —– MPH LA (Ritalin LA)
