Which agency oversees the safety and efficacy of the nation's drug supply?

• A. U.S. Department of Justice Drug Enforcement Administration (DEA)
• B. U.S. Food and Drug Administration (FDA)
• C. Environmental Protection Agency (EPA)
• D. State Boards of Pharmacy

Answer: (B)

The agency responsible for ensuring the safety and effectiveness of drugs available to the public is the FDA. Before a new medication can be marketed, the FDA reviews data from laboratory studies and human clinical trials to determine that the drug provides more benefit than risk. If it meets safety and efficacy standards, the FDA approves it and then sets labeling, dosing guidelines, and manufacturing requirements to ensure consistent quality through Good Manufacturing Practices. After a drug is on the market, the FDA continues to monitor safety, collects adverse event reports, and can require actions like labeling changes or recalls if new risks emerge.

Other agencies have different roles: the Drug Enforcement Administration focuses on controlling illegal drug distribution; the Environmental Protection Agency regulates environmental impacts of chemicals and some pesticides; and State Boards of Pharmacy oversee pharmacist licensure and practice within a state, including dispensing practices, but they do not oversee nationwide drug safety and efficacy approvals.
