Which description best fits a drug?
A A substance that must bind a receptor and activate it to qualify as a drug
B A substance that alters body function only when it reaches systemic circulation
C A chemical substance used only to treat or cure an existing disease

2 SHORT ANSWER
A researcher tracks how a drug is absorbed, distributed, metabolized, and excreted over time. What field is being
studied?
3 TRUE / FALSE
Pharmacodynamics studies how a drug produces effects on the body, including its mechanism of action and the
relationship between concentration and response.
True False
