Before human testing, laboratory animal testing is required for which products?

• A. Prescription and Over-the-Counter Drugs
• B. Cosmetics and personal care items only
• C. Food supplements only
• D. Medical devices only

Answer: (A)

Before human testing, products intended to treat or prevent disease undergo animal testing to evaluate safety and pharmacological effects. This preclinical work is required for medicines because regulators use animal data to estimate safe starting doses for humans, identify potential toxicities, and establish risk versus benefit before any clinical trial in people can begin. That is why prescription and over-the-counter drugs specifically must show this animal safety and efficacy groundwork before an Investigational New Drug or equivalent human study can be approved.

Other product categories follow different paths. Cosmetics and personal care items are not universally required to undergo animal testing before human use, and many regions encourage or require non-animal safety assessments. Food supplements rely on separate safety and manufacturing controls rather than mandatory animal toxicology data for human trials, and medical devices have their own regulatory criteria that may or may not include animal testing depending on risk class and intended use.
