41
What percent of drugs are not FDA approved for children? What percent of drugs are missing dosing efficacy and safety in children?
1. 60 percent not approved by FDA | 2. 75 percent missing efficacy
42
What is not regulated by FDA?
CAM (complementary alternative medications)
43
What changes were made recently to OTC drugs?
Changed from "not for use for under 4yo" to "not for use for under 2yo"

round UP (no more than 10 percent of total dose)
45
What is a suspension?
undissolved particles of drug suspended in solution
46
What do you need to do with a suspension before distribution?
SHAKE IT!
47

TMP component
51
What part of amox/clavunate so you want to calculate the dose for?
amoxicillin
52
What are crucial measurements that need to be accurate for dosing in children?
height, weight
53

cough and cold medicines
54
Other than benzonotate, what else can be poisonous in children?
elemental iron
55
What is youngs rule?
using age to calculate dose
56
How is absorption different in neonates?
higher gastric ph, irregular peristalsis, decreased pancreatic enzymes, bile acids alter absorption
57
How does diarrhea in children alter absorption?
decreases absorption
58
How is topical absorption different in neonate/children?
topical absorption is higher in neonate/infants
59
How is body water different in infants?
adults are 50-60 percent water full term infants are 70-75 pre term infants are 85
60
How does having more body water affect distribution?
Impacts water soluble drugs (does not impact lipid-soluble drugs)
61
How does having low body fat in infants affect drug distribution?
drugs w/lipid affinity will have more free drug
62
What is different about serum proteins in infants?
less bound to albumin in infants (adult albumin level at 1yo)
63
What is different in neonates in regards to their metabolism?
Less P450 activity (phase 1 reactions impaired)
64
What is different about hepatic metabolism in neonates?
2x the adult rate @6 months, lasting until 9-12yo (anticonvulsants)
65
If a mother is taking phenobarbitol, how would that affect the baby?

They have less B-Receptors until 8yo, so B-agonists affected -also increased dystonic reactions to metoclopramide
71
How do you treat otitis externa?
1. otic suspensions (are acidic to replicate ear canal-- will be PAINFUL if vent tubes or perforation present) 2. If vent tubes/perf use ophthalamic suspensions because they have a balanced pH and are more viscous
72
Why is benzocaine preferable to lidocaine?
- preferable for topical mucosal admin | - it is poorly soluble in water and very slowly absorbed so doesn't reach toxic levels as early as lidocaine
73
What do you have to be careful with when it comes to fluoroquinolones?
joint space crystallization
74
What are examples of fluoroquinolones?
ciprofloxacin, levofloxacin, moxifloxacin

77
What are erythromycin and clrithromycin metabolized/excreted?
primarily hepatic concentration/metabolism biliary excretion
78
What effects do clarithro and erythro have?
P450 interactions, nausea, increased gastric motility
79
What is azithromycin metabolized/excreted?
tissue and macrophage concentration, minimal hepatic metabolism excreted via bile
