Category 4 under the 797 standards is designed for the highest level of environmental control. This category encompasses compounded sterile preparations that involve higher risk factors, necessitating more stringent controls to ensure the safety and sterility of the products.

In this category, the compounding environment must maintain a sterile condition to protect patients from potential contamination. This includes rigorous practices like using cleanrooms and advanced air filtration systems, along with the need for meticulous procedures when handling hazardous substances. Category 4 is essential for ensuring that preparations posing the greatest risk do not compromise patient safety, making it critical for healthcare settings dealing with vulnerable populations or complex therapies.

Categories 1, 2, and 3 impose lower requirements regarding environmental controls, focusing primarily on standard sterile compounding processes, which may not need the same level of rigorous monitoring or protective measures as those demanded by Category 4. Thus, Category 4's requirements reflect the need for enhanced environmental controls to mitigate the risk associated with higher complexity formulations.
