Which category includes CSPs prepared in an ISO class 5 environment but in an uncontrolled space?

The category that includes compounded sterile preparations (CSPs) made in an ISO class 5 environment but in an uncontrolled space is indeed Category 1.

Category 1 CSPs are those that are prepared using good compounding practices and are dispensed in situations that do not require environmental control as stringent as those required by higher categories. These preparations are typically made in an ISO class 5 environment, which indicates that the air quality is appropriate to minimize the risk of contamination. However, the lack of additional controls in the surrounding environment does increase the potential risk for microbial contamination and chemical stability issues.

In contrast, other categories involve stricter guidelines regarding environmental controls or specific preparation conditions, which are not applicable when discussing preparations made specifically in uncontrolled spaces. Thus, Category 1 is the appropriate choice since it acknowledges the less restrictive environment of preparation while still maintaining good compounding practices in ISO class 5 air quality.
