A: localized
D: skin-limited
advantage and disadvantage of transdermal administration?
A: prolonged systemic effect
D: works with only certain meds
advantage and disadvantage of inhalation administration?
A: direct delivery to respiratory system
D: limitations of resp. meds

pharmacokinetics vs pharmacodynamics
kinetics - body's effects on drug
dynamics - drug's effects on body
4 concepts of pharmacokinetics
absorption
distribution
metabolism (biotransformation)
excretion
absorption
entering bloodsteam
factors impacting absorption rate
amount: intensity of effects
route:
distribution
traveling of meds to sites of action
factors influencing distribution
circulation
tissue permeability
plasma protein binding: proteins can bind to drugs for extended effects while free
drugs perfuse through membrane
metabolism
meds changing into inactive forms
factorings influencing metabolism
, Page 4 of 49
age
metabolizing enzyme activity/amount
first-pass effect
nutritional status
similar metabolic pathways (for medications)
excretion
mainly kidneys eliminating meds
other sites: liver, lungs, intestines, exocrine glands
factors influencing excretion
kidney function (BUN/creatinine): increased values = less filtering
GFR
half life of medication
time required for
concentration to decrease by
half
can predict duration and dosing intervals
bioavailability
amount of drug reaching circulation unchanged
IV = 100%
factors influencing bioavailability
absorption
first pass
drug formulation
onset
peak
duration
O: initial therapeutic effect
P: full therapeutic effect
