Pharmacology is the study of the biologic effects of chemicals. Nurses are involved
with clinical pharmacology or pharmacotherapeutics, which is a branch of
pharmacology that deals with the uses of drugs to treat, prevent, and diagnose disease.
The radiology nurse is administering a drug to help diagnose a disease. The oncology
nurse is administering a drug to help treat a disease. Pharmacoeconomics includes any
costs involved in drug therapy. Pharmacodynamics involves how a drug affects the
body and pharmacokinetics is how the body acts on the body.
