26
How does a drug move through the body?
after a drug is given (except topical), it makes its way into the bloodstream (absorption), then to its intended tissue (distribution)

Drug elimination usually requires _______________.
biotransformation and excretion
29
What are metabolites?
resulting drug components after biotransformation and excretion

What is pharmacodynamics?
the study of the mechanisms by which drugs produce physiological changes in the body
31
How do drugs "work"?

What is affinity?
tendency of a drug to bind to a receptor
33
What is an agonist?
high level affinity

What is an antagonist?
a drug that blocks another drug from combining with a receptor
35
What is efficacy?
represent the degree to which a drug produces a response in a patient
36
What is therapeutic index?
relationship between drugs ability to achieve desired effect and tendency to cause toxic effects (expressed as a ratio), quantitates margin of safety
37
What is an adverse drug event?
harm to patient caused by administration of a drug
38

a pharmacologic response to a drug that is caused by the presence of a second drug
39
What is a pharmacokinetic interaction?
absorption, distribution, metabolism, or excretion changed by another drug
40
What is a pharmacodynamic interaction?
the action or effect of one drug is altered by another
