CSPs prepared in an ISO class 5 environment with a classified cleanroom suite fall under which category?

• A. Category 1
• B. Category 2
• C. Category 3
• D. Category 4

Answer: (B)

CSPs, or Compounded Sterile Preparations, prepared in an ISO class 5 environment with a classified cleanroom suite are classified as Category 2. This classification is essential for understanding the environmental controls and requirements for compounding sterile products.

The Category 2 designation is specifically designed for CSPs that are prepared under more controlled conditions, focusing on ensuring that these preparations will maintain sterility and are defined by specific storage times and methods when dealing with non-hazardous and some hazardous drugs. An ISO class 5 environment meets the required standards for limiting airborne particles specifically aimed at creating a sterile environment, which is critical for the preparation of these types of compounds.

In contrast, Category 1 and Category 3 designs are attributed to different levels of risk and specific conditions that don’t align with the enhanced control measures associated with sterile compounding in an ISO class 5 environment. Category 4 is focused on compounding involving hazardous drugs within stricter guidelines and does not apply to non-hazardous preparations in a cleanroom setting. Thus, the correct classification for CSPs prepared in an ISO class 5 environment is indeed Category 2.
