Administering Medication
Pharmacology
Pharmacology is the study of medicines, including:
•
The source of the drug
•
The composition of the drug
•
The effects of the drug
Administering Medication
Drug Groups
The Veterinary Medicines Regulations classify all animal medicines into one
of four categories:
•
POM-V (Prescription Only Medicine – Veterinarian) – must be prescribed by a
veterinary surgeon, and can be dispensed by any veterinary surgeon or
pharmacist
•
Examples of POM-V medications include vaccinations or antibiotics.
Administering Medication
Drug Groups
•
POM-VPS (Prescription Only Medicine – Veterinarian, Pharmacist, Suitably
Qualified Person)– must be prescribed by a veterinary surgeon, pharmacist
or SQP, and can be dispensed by any of those persons
•
Examples of POM-VPS medicines include many medications for horses and
farm animals.
Administering Medication
Drug Groups
•
NFA-VPS (Non-Food Animal medicine – Veterinarian, Pharmacist, Suitably
Qualified Person) – must be supplied by a veterinary surgeon, pharmacist
or SQP
•
Examples of NFA-VPS medicines include certain flea and worm treatments.
Administering Medication
Drug Groups
•
AVM-GSL (Authorised Veterinary Medicine – General Sales List) – can be
supplied by anyone.
•
Examples include vitamins and minerals.
Administering Medication
Controlled Drugs
•
Controlled Drugs are a special category of drugs that can be misused by
humans.
•
Controlled drugs are regulated by the Misuse of Drugs Regulations 1985,
which divides them into five different groups.
•
These groups are either banned from possession or use, have their use
carefully monitored, or must be kept in a locked cupboard, depending on
how dangerous they are.
•
An example of a controlled drug is morphine.
Administering Medication
Drug Routes
•
Drugs may be administered in various ways. The route chosen depends on
the part of the body the drug needs to affect, how quickly the drug needs to
work, and the ability of the owner to give the drug.
Administering Medication
Topical
Some drugs can be applied directly to where they are needed. These are called
TOPICAL preparations and can be used to treat eye, ear or skin problems.
Topical preparations are available in different forms:-
•
•
•
•
•
CREAMS – the drug is dissolved in water and mixed with oil or fat. Creams
spread easily and penetrate the outer layers of the skin.
OINTMENTS – the drugs are present in a base of wax or fat. They do not
penetrate the skin.
POWDERS – fine powders to apply to the skin e.g. flea powders.
MEDICATED SHAMPOOS – drugs mixed with detergents which penetrate
the coat. Shampoos are left in contact with the skin for the recommended
amount of time and then should be rinsed off thoroughly.
SPRAYS – a way of applying liquids in fine droplet form e.g. flea sprays.
Administering Medication
Examples
•
EYE & EAR MEDICATIONS – these are both
examples of topical medication.
•
Eye medications should be sterile. Once they
have been opened they should be stored only
for the length of time recommended by the
manufacturer.
Administering Medication
Systemic
•
Some drugs cannot be applied directly where they are needed. Instead they
need to travel through the animal’s system until they get to where they are
needed. These drugs are said to be given SYSTEMICALLY.
•
Examples include oral preparations and injections.
Administering Medication
Oral Preparations
•
These are given by mouth. This is often the only way that owners can give
medications to their pets.
•
There are some problems with giving drugs orally-
•
It takes longer for a drug to be absorbed into the bloodstream than if the
drug was given by injection
•
Some drugs may be broken down by digestive enzymes
•
Having food in the gut may slow down the absorption of the drug
Administering Medication
Oral Preparations
•
TABLETS – tablets are made by taking a
powdered drug and compressing it.
•
Many tablets are then coated with another
substance e.g sugar coating.
•
This coating protects the tablet from moisture and
hides any bitter taste.
•
Crushing a coated tablet destroys this protective
layer so always check if a tablet can be crushed
first.
Administering Medication
Oral Preparations
•
CAPSULES – capsules are made up of
powder or granules inside a gelatine capsule
•
MEDICINES – liquid medicines contain the
drug dissolved or suspended in water.
Suspensions need to be shaken well before
dosing.
Administering Medication
Parenteral Preparations
•
These are drugs that can be given by injection.
All drugs in this form must be sterile. The most
common routes of injection of drugs in small
animal practice are:-
•
INTRAVENOUS (I/V) – directly into a vein
•
INTRAMUSCULAR (I/M) – into a muscle
•
SUBCUTANEOUS (S/CUT) – under the skin
(usually given into the scruff of the neck)
•
INTRAPERITONEAL (I/P)– into the abdomen
Administering Medication
Parenteral Preparations
Other methods include:
•
NASAL – up the nose (e.g. kennel cough vaccine)
•
RECTAL – into the rectum (e.g. diazepam to stop fits)
Administering Medication
Health & Safety and Administering Medicines
•
Health and safety should be considered in order to make sure that we don’t
get hurt whilst administering medicines.
•
It is also important to ensure that the animal doesn’t get hurt or frightened.
