What is the purpose of an ante-room in sterile compounding?

The purpose of an ante-room in sterile compounding is to serve as a transition space between unclassified areas and the buffer room, which is the area where sterile compounding takes place. This designated area helps to ensure that the airflow and environmental conditions can be controlled, thereby minimizing the risk of contamination to the sterile products being prepared.

The ante-room helps in preparing staff, materials, and equipment before they enter the buffer room, which is crucial in maintaining the sterility of the compounded products. Activities like handwashing, gowning, and donning personal protective equipment occur here to minimize the particulate and microbial load that could affect the sterility of compounded preparations.

In contrast, while the ante-room may have some space for equipment storage, its primary function is not for equipment storage. Compounding activities must specifically be performed within the controlled environment of the buffer room, not in the ante-room. Additionally, though cleaning procedures may occur, the ante-room is not limited to cleaning but supports the entire process leading into the sterile compounding space.
