What is the BUD for Category 3 compounding?

The correct answer is based on the guidelines established for compounded sterile preparations categorized under Category 3, which are intended for use in a more controlled environment but can still present various risks for contamination and degradation over time.

For Category 3 compounding, the Beyond Use Date (BUD) is set at 90 days when stored under refrigeration. This longer BUD reflects the enhanced stability of preparations made with sterile techniques that include more stringent controls against contaminants, allowing them to maintain their efficacy for an extended period when handled properly.

This time frame is essential for ensuring patient safety and effective treatment, as it allows for the effective management of compounded preparations that may need to be used within a specified time to remain potent and safe. Understanding these durability timelines is crucial for professional practice in sterile compounding to prevent wastage while ensuring patient care quality.
