The term pharmacology is defined as which of the following?

• A. The study of drugs and their actions on the body
• B. The study of drug excretion from the body
• C. The study of how medications affect the brain
• D. The study of drugs produced illegally

Answer: (A)

Pharmacology is about how drugs interact with living organisms. It isn’t limited to one organ or to a single process; it covers what drugs do to the body (therapeutic and adverse effects) and, in a broader sense, how the body handles drugs (absorption, distribution, metabolism, and excretion). The strongest description emphasizes the study of drugs and their actions on the body, which is the core idea behind pharmacology. The other options are too narrow or off-target. Excretion describes only one aspect of how the body processes drugs, not the full scope of pharmacology. Focusing on how medications affect the brain narrows pharmacology to neuropharmacology and to one organ system rather than the whole body. Studying drugs produced illegally fits under certain topics within pharmacology or toxicology but does not define the field itself.
