UPDATE
define agonist
A drug with a high level of affinity and efficacy that binds to a receptor and casues a
specific action.
define contraindiction
a reason not to use a drug in a particular situation, causes undesirable side effects
define efficacy
the degree to which a drug produces its desired response.
define over the counter drug
a drug that may be purchased without a prescription from a vet
define prescription drug
a drug that must be prescribed by a vet and taken while under the supervision of a vet
define receptor
a molecule located on a cell that binds with drugs or neurotransmitters to cause an
effect
define therapeutic index
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
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
the relationship that must exist between the veterinarians, hris or her patient and the
patient's owner before prescription drugs may be dispensed
List four sources of drugs used in veterinary medicine
, animal products, plant products, minerals, and synthetic products
what are four components of a drug regimen
includes the dose, the route of administration, the frequency of administration, and the
duration of administration
discuss the conditions that must be met before a valid veterinarian-client-patient
relationship can be shown to exist.
1. the vet must assume responsibility for making clinical judgements in relation to the
health of the animal. 2. the vet must have recently seen the animal and be acquainted
with its care and 3. the vet must be available for follow up care of the animal.
discuss the responsibilities of a veterinary technician in the administration of
drug orders.
carry out orders correctly, read the drug label 3x to ensure that the proper drug is being
adminstered and take care to administer the correct dose by the correct route. be aware
of posibble side effects and monitor patient in a responsible way.
Describe the sequense of events that a drug undergoes from administration to
excretion.
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.
List 11 possible routes for administering a drug and discuss the advatages and/or
disadvantages of each.
1. oral route 2. SQ 3.IM 4. IV 5. IP 6. IA, intraarterial 7. IC, intracardiac 8. IM,
intramedullary 9. Inhalation 10. topical 11. intradermal
List some of the factors that influence drug absorption
1. method of absorbtion, 2. the ph of the durg and its ionization status, 3. the absorptive
surface area, 4. the blood supply to the area, 5. the solubility of the drug, 6. the dosage
form, 7. the status of the gi tract 8 interactions with other drugs
