Which term refers to a substance used in the diagnosis, treatment, or prevention of a disease?

• A. Drug
• B. Ethical Drug
• C. Excretion
• D. Generic

Answer: (A)

A substance used to diagnose, treat, or prevent disease is called a drug. Drugs include medicines prescribed by a clinician as well as over-the-counter products that help relieve symptoms or prevent illness. They work by interacting with the body’s systems to influence how disease processes unfold or how the body responds to illness. Using them safely involves correct dosing, timing, and awareness of possible side effects or interactions with other substances. Excretion is the process of eliminating wastes from the body, not a substance used for diagnosis or treatment. A generic drug refers to a non-brand-name version that contains the same active ingredient as a brand-name product; it describes naming and cost, not the function of the substance. An ethical drug isn’t a standard term used to classify medicines in this context.
