Substances used to diagnose, cure, mitigate, treat, or prevent disease are commonly known as what?

• A. Drugs
• B. Therapies
• C. Remedies
• D. Medicines

Answer: (A)

Substances used to diagnose, cure, mitigate, treat, or prevent disease are called drugs. This term specifically names the chemical or biological agents that produce therapeutic effects in the body, whether they’re natural or synthetic and whether given as pills, injections, inhalants, or other forms. It’s helpful to distinguish drugs from therapies, which are the methods or approaches of treatment (like surgery or psychotherapy) rather than the agents themselves. Medicines is a common everyday term, but in pharmacology the precise label for the active agents used to manage disease is drugs, while remedies is a broader, less precise term that often implies traditional or non-evidence-based treatments. An example is aspirin, a drug used to relieve pain and reduce risk of heart-related events, illustrating how a substance with a pharmacologic action fits the definition.
