If a drug does not meet assay limits, how is it classified?

1. Misbranded

2. Adulterated

3. Neither

4. Both

The correct answer is: Neither

When evaluating the classification of a drug that does not meet assay limits, it is important to understand the definitions of misbranding and adulteration under pharmaceutical regulations. A drug that fails to meet its assay limits is considered adulterated because it does not conform to the quality standards established by regulatory authorities. Adulteration typically refers to a product that is contaminated or does not meet the purity, strength, or quality standards required for safe consumption. If an assay fails, this would indicate that the drug may not contain the proper amount of active ingredient or may be contaminated, thus compromising its safety and effectiveness. On the other hand, misbranding generally pertains to issues related to labeling or marketing rather than the substance of the drug itself. Misbranding might occur if a drug's labeling is false or misleading, but it focuses on the representation of the product rather than its formulation or quality. Given this context, a drug that does not meet assay limits would specifically be classified as adulterated, rather than being classified as neither or both. Therefore, the interpretation that a lack of meeting assay limits does not indicate misbranding or anything else categorically incorrect, supports that it is not classified as “C” (neither) but should correctly be seen as adulterated.
