Arizona MPJE (Pharmacy Jurisprudence) Practice Exam

Drugs that fail to meet the purity or strength standards established by USP/NF are considered:

1. Misbranded

2. Adulterated

3. Counterfeit

4. Expired

The correct answer is: Misbranded

The correct answer is that drugs failing to meet the purity or strength standards established by USP/NF are considered adulterated. Adulteration refers to the situation where a drug's composition has been compromised, making it impure or less effective than the standards established by the United States Pharmacopeia/National Formulary (USP/NF). This could occur due to contamination, incorrect manufacturing practices, or degradation over time. When a drug does not adhere to the quality specifications set forth by these authoritative standards, it poses a risk to patient safety and is classified as adulterated. In contrast, misbranding pertains to labeling issues or marketing claims that may be misleading but do not directly impact the drug's quality or purity. Counterfeit drugs involve the fraudulent production of medications that may use false labeling or imitation of legitimate products, which may or may not adhere to USP/NF standards. Expired products refer to drugs that have passed their designated shelf life, affecting efficacy but not necessarily their adherence to USP/NF standards before expiration.
