What defines a Category 1 CSP?

A Category 1 Compounded Sterile Preparation (CSP) is specifically defined as a preparation that is for immediate use and does not require stringent environmental controls or the utilization of sterile compounding facilities. This means that Category 1 CSPs can be prepared in a manner that is more flexible than other categories, such as those requiring controlled environments or lengthy stability.

The focus of Category 1 is on preparations that are made under conditions that maintain sterility due to the nature of their immediate use, which typically includes situations like emergency situations where rapid intervention is necessary.

This classification allows for flexibility in compounding practices, recognizing that certain preparations can be made quickly and effectively without the more cumbersome requirements that other categories entail. Thus, it's vital for practitioners to understand that the primary feature defining a Category 1 CSP is indeed its immediacy and lack of requirement for strict environmental controls.
