Test 1 Flashcards
undesired effects associated with a drug
side effects
What can result from drug interacting with multiple tissue types, multiple cellular targets, alteration in patients physiology and/or drug pharmacokinetics?
side effects
What can occur at standard or inappropriate doses, arise when other drugs are given concurrently, or occur as result of altered drug PK?
adverse reactions
