adverse reaction
harmful or unpleasant rxn
what predicts hazard from future administrations
adverse rxns
ABCDEF adverse rxns
- augmented
- bizzarre
- chronic
- delayed
- end of use
- failure
difference between dose related and non dose related
dose-related is common and predictable vs non- is not and high mortality.. (allergic rxn)
dose and time related (chronic)
uncommon, related to cum. dose over time
adverse reaction 5 rights
right:
- drug
- patient
- dose
- route
- time
bioavailability can be altered by
- route of admin
- acid/base of drug
- acid/base of environment
- absorption
- bound/unbound
- first pass effect
- excretion/elimination

inverse
difference between weak acid and bases
