pediatric pharma Flashcards
5 keys to pharmacokinetics
- compliance
- absorption
- distribution
- metabolism
- excretion
3 keys to good compliance
- communication
- education
- monitoring
3 risk factors for compliance
- polypharma
- chronic treatment
- adol.
what is different about absorption in infants
gastric peristalsis uncoordianted and shorter
leads to :
- variable Tmax
- variable mag. of absorption
3 factors that affect absorption
- dia
- vomit
- fever
3 keys that change dist. in neonates
- albumin only 80%
- glycoprotien only 30%
- interfering substances
»> all lead to inrc. unbound substances
def. apparent volume of dist.
theoretical volume of fluid into which total drug administered would have to go into to be diluted to the concentration in plasma
what happens to vol. dist. if highly protein bound or highly taken up by tissues
protein bound - small VD
taken up - large VD
how do neonates/children/adults differ in their hepatic/renal clearance
neonates - less
children -more
how to change loading dose and maintenance dose of caffein for neonate
loading - same
maintenance - lower
how common are medication errors
10%
prob. with decimal placements
cause a 10x error
3 most common drug kills
- analgesic
- antihistamines
- sedatives
7 drug types that kill in one
- CCBs
- camphor
- narcos
- aspirin
- antidep
- patches
- diabetes
5 drugs with peds. specific SEs
- tetracycline - teeth discolor
- valproic acid - liver failure
- enthanol - hypoglycemia
- sulfonamide - kernicterus
- reyes’ - aspirin
