Norepinephrine

Question 13

Pharmacokinetics

Answer 13

What the body does to a drug/How it handles or processes it

Question 14

Pharmacodynamics

Answer 14

What the drug does to the body (effects of a drug)

Question 15

Dose vs Dosage

Answer 15

Dose - specific amount of a medication

Dosage - frequency or duration of dose

Question 16

Idiosyncrasy

Answer 16

Drug effect unique to an individual

Question 17

Cross Tolerance

Answer 17

tolerance for a drug that develops after administration of a different drug

Question 18

Tachyphylaxis

Answer 18

rapidly occurring tolerance to a drug

Question 19

Cumulative Effect

Answer 19

Increased effectiveness when a drug is given in several doses

Question 20

Drug Antagonism

Answer 20

the effects of one drug lock the response to another drug

Question 21

Summation

Answer 21

known as the additive effect, two drugs with the same effect are given together, 1+1=2

Question 22

Synergism

Answer 22

two drugs with the same effect are given together and produce a response greater than the sum of their individual responses, 1+1=3

Question 23

Potentiation

Answer 23

one drug enhances the effect of another

Question 24

Interference

Answer 24

direct biochemical interaction between two drugs; one drug affects the pharmacology of another drug
