- Median effective dose-
-Therapeutic dose for 50% of animals tested
To determine Therapeutic Index
- LD50/ Median effective dose

outcomes (the specific outcome is measurable) - this is the planning phase of ANPIE
specific patient behaviors or responses that meet or achieve patient human needs. specific and measurable
additive effects
similiar or equivalent to the sum of the individual effects 1 + 1 = 2
adverse drug event (the event is the admin’s fault)
undesirable occurance related to administering or failing to administer meds
adverse drug reaction (the reaction is therapeutic)
unexpected, unintended, undesired response given at theraupetic doses (unlike an overdose)
adverse effects
undesirable effects that are a direct response to one or more drugs
agonist
drug that stimulates the activity of one or more receptors
antagonist effect
1 + 1 = less than 2. a substance that stops the action or effect of another substance. also called inhibitors
bioavailability (available to absorb)
a measure of the extent of drug absorption for a given drug and route (from 0 - 100%)
biotransformation
one or more biochemical reactions involving a parent drug. occurs mainly in the liver and produces a metabolite that is either active or inactive. also called metabolism.
cytochrome P-450
general name for a larger class of enzymes that plays significant role in drug metabolism and interactions
dependence (your dependence is compulsive)
compulsive or chronic need for a drug
dissolution (before entering where?)
solid form disentigartes in gi tract and becomes soluble before entering circulation
drug
a chemical that affects the phsyiology of a living thing
drug effect
The physiologic reaction of the body to the drug
can be good or bad
teratogenic
Structural defects to Fetus
duration
The time a drug concentration is sufficient to elicit a
therapeutic response
first pass
initial metabolism in liver before reaching ciriculation
high first pass rate
a large amount of drug is absorbed by liver and less will reach target sites
glucose-6-phosphate dehydrogenase
hereditary - RBC break down when body is exposed to certain drugs
incompatability
2 parental drugs when mixed together result in deteroration of one drug
medication use process
prescribing, despensing, admin of meds and their effects
metabolite
chemical form of a drug that is the product of one ore more biochemical reactions involving parent drug. active metabolites have activity of their own, even if parent drug is inactive. inactive are drug waste products.
onsest
time to reach therapeutic response

from natural plants or animals
pharmacokinetics (what does coke-netics do to the body from start to finish)
body does to the drug.
- Absorption
- Distribution
- Metabolism
-Excretion
