Which act distinguished between legend (prescription) and nonlegend (OTC) drugs?

• A. Durham-Humphrey Amendment
• B. Kefauver-Harris Amendment
• C. Orphan Drug Act
• D. Harrison Narcotic Act

Answer: (D)

The idea being tested is how drugs are classified as prescription versus over-the-counter. That classification was created by the Durham-Humphrey Amendment to the Federal Food, Drug, and Cosmetic Act in 1951. This amendment established two distinct categories: prescription (legend) drugs, which require a valid doctor’s order, and nonprescription (OTC) drugs, which can be sold directly to consumers. It also allowed verbal or telephone orders and refills for prescription medications and required labeling that warned about the necessity of a prescription. In short, it formalized the distinction between legend and nonlegend drugs and defined how each is dispensed and labeled. The other acts don’t fit this specific distinction. The Harrison Narcotic Act focused on regulating narcotics themselves rather than creating the general prescription-versus-OTC framework. The Kefauver-Harris Amendment addressed drug safety and efficacy requirements. The Orphan Drug Act provides incentives for developing treatments for rare diseases.
