USP 797 Cleanroom

Pharmacies that prepare Compounding Sterile Preparations (CSPs) must follow standards created by the United States Pharmacopeia (USP) chapter 797.

The compounding facility must comply with clean room classifications as defined by the International Organization for Standardization (ISO) in order to create a safe, clean environment.

Primary Engineering Controls (PECs) must meet ISO 5 clean room requirements. This is commonly achieved with laminar airflow workbenches or compounding aseptic isolators that are located in an ISO Class 7 clean-rooms.

A compounding aseptic isolator (CAI) is positively pressured with HEPA filtered air and used for compounding non-hazardous drugs.

What Is USP 797?

USP 797 is a publication issued by the United States Pharmacopeia in order to improve the safety of the compounding environment and all the products made in that environment.
