South Carolina Multistate Pharmacy Jurisprudence Examination (MPJE) Practice Exam

What is the expiration period for water-containing products?

1. 7 days

2. 14 days

3. 30 days

4. 60 days

The correct answer is: 14 days

The correct expiration period for water-containing products is 14 days when stored at controlled room temperature. This guideline is established to ensure the stability and safety of these products, as water can promote microbial growth, leading to potential contamination and compromised effectiveness. In the pharmacy setting, this is particularly important for products such as compounded preparations that include aqueous solutions. The 14-day expiration is intended to minimize risks associated with the use of these products after a certain timeframe, ensuring patients receive effective and safe medications. Other options like 7 days, 30 days, and 60 days do not align with standard regulations or guidelines for the stability of compounded water-containing products, which is why they are not the correct answer. Understanding the specific expiration periods of different types of pharmaceutical products is crucial for maintaining quality control in pharmacy practice.
