A drug agonist is an extrinsic drug that activates the receptor sites of a cell and mimics the actions

pharmacologic term.

6. Which term describes how the body affects drug activity?
a. Drug potency
b Pharmacodynamics
.
c. Therapeutic effect
d Pharmacokinetics

SELECTED ANSWER: D
The term pharmacokinetics refers to drug metabolism and how the body changes a drug.
Pharmacodynamics refers to how a drug works to change body function. Drug potency refers to
how strongly or to what degree a drug exerts its effects. The therapeutic effect is closer to
pharmacodynamics, meaning how a drug works to change body function.
