Exam 4 Flashcards
Lab findings in ADHD
- Dec total brain volume
- Dec activity in prefrontal and anterior cingulate cortex
- Lack of connectivity of ventral striatum
-Default mode network overactivity
Symptoms of ADHD
- Inattention
- Hyperactivity
- Impulsivity
- 6 or more present for more than 6 months in children, adults 5
ADHD Diagnosis pearls
- always drug test (in order to rule out alternative causes)
- evaluate every child 4-18 with behavioral or academic problems
- significant impairment in 2 or more settings
Consequences of untreated ADHD
- delay in language, motor, and social development
- inc incidence of conflicts
- inc risk of suicide attempts in early adulthood
- inc prevalence of SUD + incarceration
Preschool/school age ADHD non pharm practices
- parent/family edu
- training on behavioral mod
- behavioral class management (BCM)
Adolescents ADHD non pharm practices
- break up assignments into segments
- structure schedule
- behavioral peer intervention
Adults ADHD non pharm options
-ADHD CBT
-Metacognitive therapy ( 2h/w x 12 weeks)
Dietary supplements in ADHD
- lack of evidence but if there’s deficiencies treat it
- iron-zinc may inc stimulate effectiveness, omega 3
Predominant ADHD first line
Methylphenidate > Amphetamine
Predominant ADHD inadequate response to first line
Atomoxetine, Viloxazine, Guanfacine, Clonidine, Bupropion
Try combos or tca next
Tourette’s
DA antagonist or a2 agonist (Clonidine)
- if patient has some response add on stimulant or atomoxetine or alternative
Bipolar/severe aggression (ADHD comorbidity)
Atypical APS, Lithium, Anticonvulsant
- if pt has some response add on A LOW DOSE stimulant (AE: mania)
Anxiety/ Depression (ADHD comorbidity)
Antidepressant (SSRI)
- if pt has some response add stimulant, no response use alternative
Stimulants MOA in ADHD
Block DA & NE uptake, inc catecholamine release, in monoamine oxidase (which inc DA in prefrontal cortex)
Immediate release amphetamines
- mixed amp- IR salts (5-20)
- amp sulfate IR (5-40)
- odt (10-40)
- d-amp-IR/liquid (2.5-40)
Stimulant AEs
- psychiatric (mania/psychosis, aggression, sever anxiety) DOSE REDUCE
- small cardiac changes ( 5 bpm inc)
- dose related dec growth (drug free trial yrly)
Stimulants DDI (6)
- MAOI (avoid, 14 day washout)
- psycho-stimulants ( coffee, sildenafil, nicotine)
- anti acids, ppis, H2RAs inc absorption of IR, dec absorption of ER MPH
- Antacids dec excretion of AMP (requiring lower doses)
- CYP2D6 inhibitors can inc AMP salt exposure (paroxetine & fluoxetine) requiring lower doses
- Alcohol can cause stimulant dumping
Common stimulant SE and ways to help (6)
- reduced appetite/ weight loss= high calf meal when stimulant effect low (AM/QHS)
- stomach ache= take with food or dec dose
- insomnia = give earlier in the day, dec last dose of day or give it earlier, give sedative meds ( guanfacine, Clonidine, melatonin, cypro)
- headache = Divide dose, take with food, give analgesic
- rebound sumptuous= LA stimulant, atomoxetine, antidepressant
- irritability/jitteriness= comorbid condition, dec dose, mood stabilizer/ atypical antipsychotics
Uncommon stimulant effects (5) and what to do
- dysphoria/euphoria
- zombie like state
- tics
- HTN
- hallucinations (D/C, reassess, mood stabilizers)
- dec dose consider alternative
Immediate release advantages
low cost, less insomnia, fewer growth related ADE
Delayed release advantages
Med adherence
Delayed release AMP
- mixed AMP-XR salts (5-30mg)
- AMP sulfate ER suspension (6.3- 12.5)
- AMP XR ODT (6.3-12.5)
- D-AMP- ER (5-40 mg)
Clinical pearls about AMP ER Soln
-2.5- 5mg
- se: epistaxis(nose bleeds), upper abdominal pain, allergic rhinitis
Clinical pearls about AMP XR ODT/Suspension
- food delays time to peak
Clinical pearls about Mydayis ( Mixed AMP Salts ER)
-onset 1-2 hrs, last 16 hours
- triple time release beads within capsules to reduce medication wearing off (better control)
Amphetamines moa at high doses
Stimulate serotonin release and acts as serotonin agonist
