Week 3 - Exam 1 Flashcards
volume from stock solution =
(small% / large%) x total volume needed
drug interaction factors by animal:
species, breed, weight, age, sex, temperament, idiosyncrasy, hypersensitivity, disease, tolerance
drug interaction factors by drug:
route and timing, accumulation, drug-drug interaction
drug interaction factors by environment:
ambient temperature, humidity, oxygen, exposure to light
cats typically weigh
5kg
labs typically weigh
30kg
horses typically weigh
500kg
pediatric patients watch for
increase total body water
geriatric patients watch for
decrease total body water & lean body mass, and increase body fat
idiosyncrasy
individual drug sensitivity, not dose dependent, serious, genetically determined unpredictable abnormal
hypersensitivity
individual allergic drug reaction, prior exposure necessary, haptens/antigens
3 types of disease that affect drug response
hepatic dysfunction, renal insufficiency, congestive heart failure
4 types of drug tolerances
natural, acquired, cross, tachyphylaxis
tolerance is
an usual resistance to ordinary drug dose
oral absorption is usually faster _____ meal
before
accumulation occurs when
rate of elimination is slower than rate of absorption
4 types of drug-drug interactions
summation, potentiation, synergism, antagonism
excretion normally referring to what organ
kidney
metabolism normally referring to what organ
liver
definition of summation
sum of the effects of drugs
definition of potentiation
intensification of effects (give another drug with different action)
definition of synergism
exaggeration of effects (give another drug with same action)
definition of antagonism
decreases effect of another drug
drug-drug interactions: pharmacodynamics
same receptors; drugs with reversals
