Under MEDIUM RISK conditions in the absence of sterility testing, how long can preparations be stored under refrigeration?

• A. 9 days
• B. 24 hours
• C. 3 days
• D. 7 days

Answer: (A)

Beyond-use dating for compounded sterile products depends on the level of risk in the preparation and the storage conditions. For medium-risk preparations that are not subjected to sterility testing, storing under refrigeration limits the BUD to nine days. This reflects the greater complexity and handling involved in medium-risk compounding and the reduced assurance of sterility without testing. Refrigeration helps slow microbial growth and chemical degradation, but without sterility confirmation, nine days provides a safety buffer to use the preparation while keeping potency and safety acceptable. If sterility testing were performed and passed, a longer BUD could be supported; different storage conditions would carry different BUDs, but under these specific conditions, nine days is the appropriate limit.
