Which statement about the Drug definition is true?

Which statement about the Drug definition is true?

• A. It includes only substances listed in pharmacopoeias
• B. It includes substances recognized in official pharmacopoeias and formularies and may be used to diagnose, cure, mitigate, treat, or prevent disease, or to affect body structure or function
• C. It excludes substances used as dietary supplements
• D. It is confined to prescription medications

Answer: (B)

The test is looking at how a drug is defined in health and safety terms: it must be a substance that is officially recognized in pharmacopoeias and formularies and is intended to diagnose, cure, mitigate, treat, or prevent disease, or to affect the structure or function of the body. This framing shows why the statement is correct: it ties together formal recognition (in pharmacopoeias/formularies) with a medical purpose or effect on the body. It also makes clear why drugs aren’t limited to prescription meds or to dietary supplements treated as medicines in every case. The other choices are too narrow or inaccurate: restricting to substances listed only in pharmacopoeias ignores the broader recognition and uses allowed by formularies; stating dietary supplements are excluded ignores the possibility that they can be used to diagnose, cure, mitigate, treat, or prevent disease or to affect body function; and confining drugs to prescription medications omits over-the-counter drugs that meet the same definition.
