Which USP guidelines are designed for non-sterile preparations?

USP 795 provides guidelines specifically for non-sterile compounding of medications. This standard establishes the procedures and best practices to ensure the safety and quality of compounded preparations that are not intended for sterility. It addresses issues such as facility requirements, equipment, training of personnel, and the overall compounding process to help minimize contamination and ensure that the compounded drugs are safe for patient use.

The other options relate to different aspects of compounding. For example, USP 797 focuses on guidelines for sterile compounding to ensure that sterile products are prepared in a safe environment to prevent contamination. USP 800 outlines the handling of hazardous drugs, ensuring that staff and patients are protected from potential risks associated with these substances. USP 400 does not pertain to compounding guidelines, as there is no such standard in the USP related to this context. Therefore, USP 795 is the correct choice regarding guidelines specifically for non-sterile preparations.
