What is the beyond-use date (BUD) for a non-sterile compound that is a non-aqueous topical formulation?

• A. 3 days at room temperature
• B. 1 month refrigerated
• C. 6 months at room temperature
• D. 2 weeks at room temperature

Answer: (C)

The beyond-use date (BUD) for a non-sterile compound that is a non-aqueous topical formulation is set at 6 months when stored at room temperature. This is based on recommendations from the United States Pharmacopeia (USP) guidelines, which provide stability parameters for compounding. Non-aqueous formulations have a longer shelf life compared to aqueous formulations because they are less susceptible to microbial contamination and degradation. The 6-month BUD is a reflection of this stability, as these compounds can maintain their integrity and potency for a longer duration when stored properly away from direct light and extreme temperatures. In contrast, choices like 3 days at room temperature or 2 weeks at room temperature are too short for non-aqueous topical formulations, which generally do not require such stringent limits. Additionally, while 1 month refrigerated may seem reasonable for certain compounds, it does not apply to this specific category of non-aqueous formulations, which have demonstrated stability at room temperature for up to 6 months.
