and answers
define agonist - answer A drug with a high level of
affinity and efficacy that binds to a receptor and
casues a specific action.
define contraindiction - answer a reason not to use
a drug in a particular situation, causes undesirable
side effects
define efficacy - answer the degree to which a

define over the counter drug - answer a drug that
may be purchased without a prescription from a
vet
,define prescription drug - answer a drug that must
be prescribed by a vet and taken while under the
supervision of a vet
define receptor - answer a molecule located on a
cell that binds with drugs or neurotransmitters to
cause an effect
define therapeutic index - answer the relationship
between a drug's ability to achieve the desired
effect compared to its tendency to produce toxic
effects. Expressed as a ration between the LD and
the ED. LD/ED 50% of the time.
define withdrawal time - answer the amount of
time that must elapse between the end of drug
therapy and the elimination of that drug from the
patients tissue or products.
define veterinarian client patient relationship -
answer the relationship that must exist between
the veterinarians, hris or her patient and the

, posibble side effects and monitor patient in a
responsible way.
Describe the sequense of events that a drug
undergoes from administration to excretion. -
answer a drug is first absorbed or directly placed
into the bloodstream. In the blood, the drug may
bind with a plasma protein or exist in the free
state. The circulating blood distributes the drug to
the capillary level, where the drug leaves the
circulation and enters the interstitial fluid. The
interstitial fluid bathes the cell or bind with surface
receptors. The drug then exits the cell or its
surface, moves back to interstitial fluid, reenters
circulation and then is metabolized in the liver and
sent to the kidneys for excretion.

intradermal
List some of the factors that influence drug
absorption - answer 1. method of absorbtion, 2.
