Question 1

Drug receptors

Answer 1

Specific sites where drugs form chemical bonds

Question 2

Pharmacodynamics

Answer 2

Study of interactions between drugs and
their receptors and the series of events that result in a
pharmacologic response

Question 3

Agonists

Answer 3

Drugs that interact with a receptor to stimulate a

response

Question 4

Antagonist

Answer 4

Drugs that attach to a receptor but do not stimulate a

response-

Question 5

Partial agonists:

Answer 5

Drugs that interact with a receptor to

stimulate a response but inhibit other responses.

Question 6

An antagonist are sometimes called

Answer 6

blockers

Question 7

partial agonist

Answer 7

bind and activate a given receptor, but have only partial efficacy at the receptor

Question 8

why are Agents like buprenorphine are used to treat opiate dependence?

Answer 8

they

produce milder effects on the opioid receptor with lower dependence and abuse potential

Question 9

Enteral

Answer 9

Via the gastrointestinal tract by the oral, rectal, or

nasogastric routes

Question 10

Parenteral

Answer 10

Bypasses the GI tract by using subcutaneous,

intramuscular, and intravenous injection

Question 11

Percutaneous

Answer 11

Absorbed through the skin and mucous

membranes (i.e. Inhalation, sublingual, or topical )

Question 12

LADME

Answer 12

liberation, absorption, distribution, metabolism, and excretion

Question 13

liberation

Answer 13

Drug released from dosage form

Question 14

absorption

Answer 14

Depends on route of administration-

Oral drugs won’t take effect as quickly as IVs

Question 15

distribution

Answer 15

Depends on circulation to be
transported throughout body-blood and lymph
systems affect drug transport.

Question 16

metabolism

Answer 16

Depends on enzyme systems-
concurrent use of other drugs, environmental
pollutants, disease processes, and age affect
this process.

Question 17

excretion

Answer 17

Depends on GI tract and kidneys-
Other excretion routes besides the GI tract and
kidneys (i.e., skin and lungs).

the site of action is sufficient to start a physiologic
response

Question 25
