For Category 2 CSPs that are Aseptically Prepared with No sterility testing results and sterile components, what is the BUD at controlled room temperature?

For Category 2 CSPs that are Aseptically Prepared with No sterility testing results and sterile components, what is the BUD at controlled room temperature?

• A. 4 days
• B. 10 days
• C. 30 days
• D. 60 days

Answer: (A)

The test here is about how sterility assurance and component sterility affect the time you can hold a compounded sterile product. When a CSP is prepared aseptically using sterile components but there are no sterility testing results for the final product, you must assign a conservative BUD to limit risk if contamination is present. For Category 2 CSPs with sterile components and no sterility test results, the BUD at controlled room temperature is four days. This short window reflects the lack of final sterility confirmation and the desire to minimize the chance of microbial growth or deterioration when stored at room temperature. If sterility testing had been performed and passed, or if the components and processes carried different validated assurances, longer BUDs could be used. The other durations would require those additional confirmations or conditions beyond this scenario.
