Which of the following is a characteristic of a low risk compounded sterile preparation (CSP)?

In the context of low-risk compounded sterile preparations (CSPs), one of the key characteristics is that they include no more than two entries into any one sterile container. This criterion is vital for ensuring that the risk of contamination during the compounding process is minimized, as limiting the number of entries reduces the potential exposure of the sterile ingredients to environmental contaminants.

Low-risk CSPs are typically prepared under conditions that maintain sterility, which usually involves using aseptic technique and preparing the compounds in a clean environment, such as a laminar flow hood. By restricting the number of times that a sterile container is accessed, the procedure adheres to guidelines that help control the risk factors involved with compounding sterile products.

Other characteristics of low-risk CSPs include the use of three or fewer sterile ingredients and the procedure being completed within a specific time frame, but these are not the focus of the selected characteristic. Understanding the conditions and limitations for compounding sterile preparations is essential, especially for pharmacists involved in sterile compounding, to ensure patient safety and compliance with regulatory standards.
