Which United States agency is charged with protecting public health and regulating medicines?

• A. CDC
• B. NIH
• C. FDA
• D. CMS

Answer: (C)

Regulation of medicines to safeguard public health is the role of the FDA. The Food and Drug Administration oversees the development, approval, labeling, manufacturing, and post-market monitoring of drugs and medical products, ensuring they are safe and effective for patients. This includes evaluating clinical trial data before a drug is approved, enforcing good manufacturing practices, and tracking adverse effects with recalls when necessary. While the CDC focuses on disease prevention and outbreak control, the NIH on biomedical research, and CMS on Medicare/Medicaid programs, none of these primarily regulate medicines for safety and efficacy. So, the agency responsible for protecting public health through drug regulation is the FDA.
