Term
Pharmacokinetic differences in pediatrics
Definition
1. GI - pH affects passive diffusion across gastric mucosa [premature infants have higher gastric pH (less acid) and neonates have rapid changes in the first 24 hours] gastric emptying time [slower in premature infants - may lead to higher drug concentration]
2. IM sites - neonates have less muscle mass, insufficient muscular contraction to move drug out of muscles, and poor diffusion to peripheral areas [IV is preferred]

Term

Definition
preemies > neonates > infants > adults
Term
Why is there an increase in free drug in neonates?

Definition
in premies theophylline does not clear as quickly, so give lower doses

in children 1-9 years theophylline is elimated faster compared to premies or adults so give higher doses
Term
What factors affect drug selection in pediatrics?
Definition
1. Carriers - propylene glycol in injectable drugs causes hyperosmolality in infants
2. preservatives - benzyl alcohol causes seizures, cardiovascular collapse, and death in premature infants
3. unique side effects in peds - tetracyclines cause dental staining and quinolones cause joint disease
4. Decrease in nephrotoxicity in infants - can use gentamycin in peds but not adults
Term

Recombinant tissue plasminogen activator (t-PA)
Term
CI for thrombolytic agents
Definition
1. recent thoracic, abdominal, or CNS surgery
2. recent CVA, trauma, or neoplasm
3. bleeding ulcer
4. malignant HTN
5. anticipated invasive procedures (arterial punctures, biopsies, central lines)
6. concurrent hemostatic dysfunction
Term
What drug class used to treat hyperlipidemia causes myopathy?
Definition
statins - rosuvastatin, atorvastatin, simvastatin, lovastatin, fluvastatin, pravastatin
Term
Myopathy caused by statins
Definition
1. see bilateral muscle pain in major muscles
2. measure with creatinine kinase
3. overall risk of myopathy is low and rhabdomyolysis is rare
4. If myopathy occurs, stop for 1 month, then use a different statin
5. adding ezetimibe to statin therapy does not increase myopathy
6. adding fibrates to statin therapy increases myopathy/rhabdomyolysis
Term
T/F
dyslipidemia is one of the treatable risk factors for coronary heart disease
Definition
True
Term
T/F
When using statins, see a decrease in adverse cardiac events even when not at treatment goal.
Definition
True - helps with plaque stability and decreases CRP
Term
__ % reduction in CHD event rates for every __ % reduction in HDL OR LDL
Definition
1% for every 1% in LDL
1% for every 2% in HDL
Term
LMWH vs. unfractionated heparin
Definition
LMWH
1. more reliable pharmacokinetic response (predictable anticoag response)
2. great sub-cu bioavailability
3. lower incidence of thrombocytopenia
4. reduced need for lab monitoring
5. longer half-life (once a day dosing)
6. dose independent clearing
Term
Side effects of amiodorone
Definition
number and severity of toxic effects increases with dosage (doses less than 200 mg/dL or less have low incidence of lung or thyroid effects)

cardiac - bradycardia, heart block, heart failure

extra-cardiac - pulmonary fibrosis, skin deposits (photodermatitis, bluish gray discoloration)

CNS (common) - paresthesia, tremor, ataxia, HA

thyroid dysfunction - Hyper or hypothyroidism (labs should be done at least every 6 months)

liver necrosis - assess at least every 6 months
Term
Describe premature ventricular contractions on EKG
Definition
broad QRS complexes (> .12 sec)
occur earlier than normal
followed by compensatory pause
Term
Management of PVCs in absence of heart disease
Definition
little risk of developing arrhythmia
antiarrhythmic therapy increases the risk of dying

DOC initially if symptomatic: beta blocker - sotalol (nonselective beta blocker)

Do not use sotalol in asymptomatic pt because of proarrhythmia effects
Term
Management of PVCs in presence of structural heart disease
Definition
radiofrequency ablation

Refer for Class I antiarrhythmic drugs or amiodarone
Term
What drug is used to reverse the anticoagulation effects of heparin (UFH and LMWH)?
Definition
protamine sulfate
Term
What drug is used to reverse the anticoagulation effects of warfarin?
Definition
injectible vitamin K
Term
ACE-I side effects (5)
Definition
1. Hypotension - pts are hypovolemic
2. Hyperkalemia - esp. if used in combo with K-sparing diuretics, KCl tablets, or an ARB
3. angioedema
4. dry cough - increased bradykinin levels
5. teratogenic - CI in pregnancy and not good choice in fertile females
Term
ARB side effects (4)
Definition
1. Hypotension - orthostatic or hypovolemia
2. Hyperkalemia - if used in combo with K-sparing diuretics, KCl tablets, ACE-I
3. angioedema - less common than ACE-I
4. CI in pregnancy
Term
What are the 3 parts of Virchow's triad for PE?
Definition
1. hemodynamic imbalance
2. hypercoagulability
3. vessel wall damage
Term
Causes of hemodynamic imbalance
Definition
burns
cancer
pregnancy
HF
major surgery
fracture
MI
stroke
Term
Causes of hypercoaguability
Definition
estrogen therapy
thrombophilias
previous VTE
pregnancy
cancer
Term
Causes of vessel wall damage
Definition
trauma
major surgery
fracture (hip or leg)
