Before humans are involved, laboratory animals must be used to test which products?

• A. Prescription and Over-the-Counter Drugs
• B. Cosmetics alone
• C. Medical devices alone
• D. Food flavorings

Answer: (A)

Before humans are involved, testing in animals is used to evaluate whether a new drug is safe and how it behaves in the body. This preclinical step helps determine potential toxicities, how the drug is absorbed and processed, and the appropriate starting dose for first-in-human trials. Regulatory agencies require this animal testing for medicines intended for human use—both prescription and over-the-counter drugs—because it provides essential safety data before people are exposed to the compound.

Other product areas have different safety pathways. Cosmetics, medical devices, and flavorings don’t universally require animal testing prior to human exposure; many regions are moving toward non-animal methods or case-by-case assessments, and some products may rely on existing toxicology data rather than animal studies.
