prescription from a veterinarian

used under the supervision of a veterinarian.
Define Receptor - ANS-A receptor is a group of specialized
molecules on or in a cell that bind with a
drug to produce an effect.
Define Therapeutic Index - ANS-The therapeutic index expresses the
relationship between a drug's therapeutic
and harmful effects
Define Withdrawl Time - ANS-The withdrawal time is the amount of time
that must elapse between the end of drug
therapy and the elimination of that drug

the veterinarian's orders correctly. The
technician should read the drug label three
times to ensure that the proper drug is being
administered and should take care to
administer the correct dose by the correct
route. The technician should also be aware of
the expected effects and the potential adverse
side effects to be able to monitor the patient in

times and potential residue problems.
Describe the sequence of events that a drug undergoes from administration to excretion
- ANS-6. A drug is first absorbed (or directly placed)into the bloodstream. In the blood,
the drug
may bind with a plasma protein or may 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 and
allows the drug to enter the cell or bind with
surface receptors. The drug then exits the cell
(or its surface), moves back into the interstitial
fluid, reenters the circulation, and is
transported to the liver for metabolism. After it
is metabolized, the metabolite is transported to
the kidneys for excretion.
