What is a primary characteristic of Category 3 CSPs?

The primary characteristic of Category 3 Compounded Sterile Preparations (CSPs) is that they are prepared under the most controlled conditions. This categorization applies to CSPs that may require more stringent procedures and quality checks due to their complexity or the specific requirements for their preparation.

Category 3 CSPs must be compounded using aseptic techniques and typically involve a higher risk of contamination. Therefore, they necessitate a controlled environment, such as a cleanroom or laminar airflow hood, to minimize that risk. The stringent conditions are meant to ensure patient safety and the integrity of the sterile product.

In the context of this category, the use of specific equipment and practices is enforced to maintain sterility and quality, which distinguishes them from lower categories with less stringent requirements. This level of control is paramount for ensuring that the final compounded product is safe for patient use.
