NAPLEX (North American Pharmacist Licensure Examination) Practice Exam

What is the BUD for water-containing oral formulations?

1. 14 days at controlled cold temperatures

2. 6 months (180 days) at room temperature

3. 30 days at room temperature

4. 28 days

The correct answer is: 14 days at controlled cold temperatures

Water-containing oral formulations are sensitive to various factors such as temperature, light, and air. This means that they have a limited shelf life and can become ineffective or even harmful if not stored properly. Therefore, the Beyond Use Date (BUD) is important to ensure the quality and safety of the medication. Option B is incorrect because storing the formulations at room temperature for 6 months is too long and may lead to degradation. Option C is incorrect because 30 days at room temperature is also considered a long period and poses a risk for potential contamination. Option D is incorrect because the standard BUD for oral formulations is usually shorter than 28 days. Therefore, option A, with a BUD of 14 days at controlled cold temperatures, is the most appropriate and safe choice for water-containing oral formulations.
