Question 39

The Durham-Humphrey Amendment of 1951 established legend and non-legend categories of medication.

This amendment differentiated between prescription and over-the-counter medications, thus creating the legend category for drugs that require a prescription and the non-legend category for those that do not.

A) Drug Listing Act of 1972

The Drug Listing Act of 1972 primarily focuses on the establishment of a comprehensive listing of all drugs, including their ingredients, strength, and dosage forms. It does not address the categorization of medications into legend and non-legend, making it incorrect for this question.

B) Durham-Humphrey Amendment of 1951

This amendment is significant as it clearly defined the roles of prescription and over-the-counter drugs, establishing the legend category for medications that require a prescription (legend drugs) and the non-legend category for those available without a prescription. This makes it the correct answer to the question.

C) Food, Drug, and Cosmetic Act of 1938

While the Food, Drug, and Cosmetic Act of 1938 was crucial in ensuring the safety and efficacy of drugs and cosmetics, it did not specifically create the legend and non-legend categories. Instead, it laid the groundwork for subsequent amendments, including the Durham-Humphrey Amendment.

D) Kefauver-Harris Amendment of 1962

The Kefauver-Harris Amendment primarily focused on drug efficacy and safety, requiring manufacturers to provide substantial evidence of a drug's effectiveness. It did not establish the legend and non-legend categories, making it irrelevant to the question.

Conclusion

The Durham-Humphrey Amendment of 1951 is the definitive law that established the distinction between legend and non-legend medications, directly addressing the requirements for prescription and over-the-counter drugs. The other options, while significant in the context of drug regulation, do not pertain to the categorization of medications as required by the question.
