The requirement for animal testing before human trials applies to drugs in what categories?

• A. Prescription and OTC drugs
• B. Medical devices
• C. Vitamins and minerals only
• D. Cosmetics only

Answer: (A)

Before humans can participate in trials of a new drug, regulators require safety testing in animals to assess toxicity, understand how the drug behaves in the body, and establish safe starting doses. This preclinical step is needed for drugs that will be used as medicines, which includes both prescription and OTC products, so animal testing is required before any human trials proceed.

Other product categories follow different regulatory paths. Medical devices are evaluated for safety and performance as devices, not as drugs, so they don’t hinge on the same drug-specific animal preclinical testing. Vitamins and minerals used as dietary supplements aren’t medicines and are governed by food/supplement safety rules rather than drug preclinical programs. Cosmetics are regulated separately, with safety data often gathered through pathways that don’t require a drug-like animal tox screening before human use.
