Final Flashcards
Indications
Reasons for giving a drug to a patient
Contraindications
Reasons for not giving a drug to a patient
Prescription (legend) drug
Drug that is regulated by the FDA due to having the ability to cause serious harm if not used in an appropriate manner
Conditions for valid VCPR
- Vet must assume responsibility for making clinical judgments
- Must have recently seen the animal and know its care
- Must be available for follow-up care
Regimen
Plan for administering drugs
Drug regimen consists of:
Kind of drug
Route of administration
Dosage
Frequency
Duration
Pharmacokinetics
Complex series of events that occurs once a drug is administered to the patient
Influences by the manner in which the drug is given
Some routes have limitations
Oral (PO)
By mouth
Contraindicated for animals with nausea/vomiting
Some taste horrible
Intravenous (IV)
Given in the vein
Takes effect almost immediately
Doesn’t last as long as drugs administered by other routes due to body eliminating drug rather quickly
Intramuscular (IM)
Given in the muscle
Sometimes painful
Absorbed more slowly than IV but faster than SQ
Subcutaneous (SQ or SC)
Given in tissue beneath the skin
Take longer to absorb than IV or IM
Intradermal (ID)
Given into the skin
Used for testing for allergies
Intraperitoneal (IP)
Given into the abdominal cavity
Intraarterial (IA)
An injection given into the artery
Intraarticular (IA)
An injection given into the joint
Intracardiac (IC)
An injection given into the heart
Used mostly for humane euthanasia and cardiopulmonary resuscitation (CPR)
Intramedullary
An injection given into the bone marrow cavity
Epidural/subdural
An injection given into the spine or near the spine
Nebulizer
Drug that can be inhaled in a fine mist
Antibiotics or bronchodilators can be inhaled into deep, small airways
Metered-dose inhaler
Administered by using a hand-held device that fits over an animal’s nose and mouth
Anesthetic gases
Gaseous forms given with vaporizers
Transdermal (topical)
Drugs that are placed on the skin
Gloves should always be worn when handling these drugs
Concentration Gradient
Drugs that move from one compartment of the body to another
Move from areas of high concentration to lower concentration
Bioavailability
Measures the amount of drug that gets absorbed and is available to the patient
