Which environment is necessary for sterile products compounded in a PEC in an SCA?

For the compounding of sterile products, the environment in which they are prepared is crucial to ensure the safety and efficacy of the products. In this context, the Primary Engineering Control (PEC) in a Sterile Compounding Area (SCA) must maintain specific cleanliness and particulate control standards.

An ISO 5 environment is necessary for the compounding of sterile products because it limits the allowable particulate matter and ensures that the environment remains free from microbial contamination during the preparation of medications. An ISO 5 cleanroom can provide a maximum allowable particle concentration of 3,520 particles per cubic meter for particles 0.5 micrometers in size, which is essential to protect the sterile products being compounded.

While ISO 7 and ISO 8 environments are certainly cleaner than unclassified spaces, they do not meet the stringent requirements necessary for sterile compounding. ISO 7 allows for more particles than ISO 5, and thus would not provide the same level of protection against contamination. The absence of a specific environmental requirement is also not applicable, as sterile compounding demands rigorous controls to minimize any contamination risks.

In sum, an ISO 5 environment is a fundamental requirement for a PEC in an SCA to ensure that sterile products are compounded safely and effectively
