Flashcards in Terminology and Dosing Deck (18):
1

Pharmacology

study of the effects of drugs on the function of living systems

2

Drug

a chemical substance of known structure that when administered to a living organism produces a biological effect

3

Pharmacokinetics

the study of absorption, distribution, metabolism, & elimination (what the body does to the drug)

4

Pharmacodynamics

what a drug does to the body

5

Over-the-counter drugs

drugs considered safe to use by a lay person

6

Prescription drug

drugs not considered safe to be used by a lay person and require a prescription; CAUTION: law restricts this drug use by or on order of a licensed veterinarian

7

Veterinary Feed Directive (VFD) drugs

drugs that are approved for use in or on animal feed under the professional supervision of a licensed veterinarian

8

Dose

quantity of drug to be taken (e.g. mg/kg, mg/lb, ml/kg)

9

1 lb = ? g

454

10

Metric prefixes

kilo: 103 milli: 10-3 micro: 10-6

11

Percent weight-to-volume (%w/v)

# of grams of a drug per 100 mls of a solution

12

Percent volume-to-volume (%v/v)

# of mls of a drug per 100 mls of a solution

13

Percent weight-to-weight (%w/w)

# of grams of a drug per 100 g of a solution

14

Drug dosing calculation

(Desired dose * weight of patient)/Concentration of drug

15

Extra-label drug use

drugs are FDA approved for human use but efficacy is untested in animals

16

What act covers extra-label drug use?

Animal Medicinal Drug Use Clarification Act of 1994

17

Important equations

Amount of drug in a solution = drug concentration * solution volume

C1 x V1 = C2 x V2

C1 x V1 + C2 x V2 = CF x V(1 + 2)
