Principles of Pharmacology Exam 1 2025
Questions and Answers
What are drugs? - --Answer --Substances that act on biologic systems at the
chemical level and alter their function.
Why are drugs used? - --Answer --They are used to treat, diagnose, or
prevent disease
What do drugs do? - --Answer --They act to increase or decrease normal
function of tissues or organs. They do not confer new functions in tissues or
organs
What is the goal of drug therapy? - --Answer --To selectively alter specific
tissue or function
How do drugs exert their beneficial effects? - --Answer --By reaching some
specific target cell or tissue and change the function of the cell either to help
restore normal physiological function or to prevent a disease process from
occurring

,Why is dosage important? - --Answer --Dosage must be generally large
enough to allow an adequate concentration to reach the target site and produce a
beneficial response without being too excessive that it causes toxicological effect
What are important basic questions a provider must ask about pharmacology? - --
Answer --1. Once a drug is taken, what happens to it?
2. Where does it go with the body?
3. What, if anything, does the body do to the drug?
4. How does the body get rid of it?
Pharmacotherapeutics - --Answer --area of pharmacology that refers to the
use of specific drugs to prevent, treat, or diagnose a disease
Pharmacodynamics - --Answer --the analysis of what the drug does to the
body, including the mechanism by which the drug exerts its effect - "what drugs do
to the body"
Pharmacokinetics - --Answer --Study of how the body absorbs, distributes,
metabolizes, and eliminates drugs - "What the body does to the drugs"

, Toxiccology - --Answer --study of the harmful effects of chemical
Pharmacy - --Answer --deals with the preparation and dispensing of
medications
Pharmacogenetics - --Answer --Deals with the genetic basis for drug
responses, especially variations in drug response from person to person
