What does "batch preparation" mean in sterile compounding?

Batch preparation in sterile compounding refers to the compounding of multiple units in a single process. This approach is typically utilized when a pharmacist anticipates needing multiple doses of a sterile preparation, allowing for efficiency and consistency in the final product. When a batch is compounded, the entire quantity is prepared at once, which helps to ensure that all units come from the same formulation and thus maintain uniform quality in terms of sterility and concentration.

In contrast, single unit compounding for immediate use focuses on preparing just the amounts necessary for one patient at that moment, lacking the efficiency of producing multiple units simultaneously. The mixing of non-sterile products is not specific to sterile compounding, as batch preparation specifically refers to sterile processes. Finally, while customized prescriptions can certainly be prepared as part of batch compounding, the main distinction lies in the fact that batch preparation encompasses the production of multiple units in a single compounding session rather than responding to on-demand prescriptions. This comprehensive understanding of batch preparation underscores its importance in maintaining quality and efficacy in sterile compounding practices.
