Veterinary Medical Applications
What is “Pharmacology”?
• The branch of veterinary medicine
concerned with the uses, effects, and
administration of drugs.
• The study of drugs.
Identifying Medications
To identify medications in the
veterinary clinic you must first identify
the following:
Classification of drug
Form of drug
Route of administration
Method of administration
Classifications of Drugs
• What is a drug classification?
–Characterized by a drug’s action(s)
in the body or on target tissues.
Classifications of Drugs
Emetics- drugs used to induce vomiting
Antiemetics- drugs that relieve vomiting
Antidiarrheal agents- drugs used to lessen diarrhea
Cathartics- drugs that increase bowel motility or loosen
stools
Classifications of Drugs
Antacids- drugs that counteract stomach acid
Diuretics- drugs that increase the production of urine
Antibiotics- drugs that kill/inhibit growth of bacteria
Anti-inflammatories- drugs that reduce inflammation
Classifications of Drugs
Analgesics-drugs that relieve pain and raise the pain
threshold
Anesthetics- drugs that decreases feeling sensation; numbing
Anticonvulsants-drugs that inhibit seizures
Stimulants-drugs that excite the functional activity of an organ
Tranquilizers- drugs that sedate/quiet an anxious patient
Forms of Drugs
• What is a form?
–Characterized by a drug’s physical
composition or state such as:
– Solid tablet, syrup, lotion, ointment,
injectable, extract, etc…
Forms of Drugs
Solid- include tablets, gel capsules & coated tablets
Solution- a drug that is dissolved in a liquid and will
not settle if left sitting; syrups and elixirs
Suspension- a drug that is suspended but not
dissolved in the liquid. The particles will settle and
must be shaken before administered
Extract- agent composed of prepared plant/animal
parts rather than manufactured chemicals
Forms of Drugs
Topical- drugs that are liquid at room temperature
and applied to the surface of the skin; include
liniments and lotions
Semisolid- drugs that are semisolid in state at
room temperature and applied to the skin; include
ointments and pastes.
Injectable- drugs that are administered via a
needle and syringe
Routes of Drug Administration
What does “route of administration”
mean?
-the pathway a drug enters the body.
– Amount of drug that reaches the target tissue can be
significantly altered if the proper route is not used.
– Each route has its own pattern (speed/degree) of
drug absorption.
Routes of Drug Administration
Intravenous- (IV) injection into the vein
Intramuscular- (IM) injection into the muscle
Subcutaneous- (Sub-Q, SQ, SC) injection below the skin
Intradermal- application through the skin
Oral- given by mouth for digestive absorption
Inhalation- administration of aerosol, mist or gas for
respiratory absorption
Methods of Drug Administration
What are methods of administration?
-The techniques used to give the
drug to the patient.
Methods of Drug Administration
1. Injection administration
(given by a shot)
2. Oral administration
(given by mouth)
3. Topical administration
(applied to surface of skin)
4. Aerosol administration
(mist or gas for respiratory tract)
It’s the law!
Controlled Substances – a substance that
has the potential for physical addiction,
physiologic addiction and/or abuse.
Controlled Substances Act of 1970 - a
practitioner who has controlled substances
stored in his/her office must keep these
drugs in a securely locked, substantially
constructed cabinet or safe.
Schedules of Controlled
Substances
C-I—No medical value, greatest restrictions; e.g., LSD, heroin
C-II—highly addictive; e.g., opium, morphine
C-III— some potential for abuse, less than C-II; e.g., ketamine
C-IV— low potential for abuse, may lead to limited
dependence; includes valium
C-V— subject to state/local regulation, low abuse potential;
least restrictions
Controlled Substances
Kept in a locked, sturdy storage cabinet.
Log must be kept of any controlled drug
that was used.
Records must state: date, purpose and
amount.
Records must include receipts of purchase
and sale of drugs.
Log must be kept for at least 2 years.
Equipment used in the
pharmacy
Pill Counter
Pill Cutter
Equipment used to
Administer Medications
Tools used to administer solid pills, capsules and caplets
Pet Piller
Balling gun
Using a Pet Piller
Equipment used to
Administer Medications
Syringes
Used to administer liquids
to a patient
– Disposable: to be
disposed of after one use
– Automatic/ Re-usable:
to be used many times
Syringes
-Identified by capacity (cc)
-larger cc syringes hold larger amounts of liquid
Equipment used to
Administer Medications
Needle Sizes come in various lengths.
– Sizes come in gauges 4-30.
– The larger the gauge #, the smaller the needle.
*Remember to dispose of properly in sharps container*
Equipment used to
Administer Medications
Notice how the smallest needle has the
largest gauge #.
Needles
Disposable
needles may be
identified by their
color code.

130.6 Veterinary Medical Applications
•
(15) The student identifies pharmacology-assisting procedures, skills, and
objectives that are included in the job description of an animal care
assistant. The student is expected to:
A. identify medications according to their classification, form, routes, and methods
of administration;
B. explain handling and distribution, protocol, and laws for controlled substances;
C. calculate dosage using factors such as concentration of drug, weight of animal,
and required dosage;
D. complete a prescription label with identifiers that are required by the United
States Food and Drug Administration; and
E. select equipment and instruments used to give medications.
