Sterilization by filtration is a critical step in the manufacturing of sterile pharmaceutical products. As described by Nelson Labs, this process assures sterility by physically removing microorganisms from the fluid stream.
Importantly, proper filtration sterilization causes no adverse effects to product quality. It is especially important in dealing with thermally sensitive products.
In this Pharma Matters Q&A, Tonya Morris, Nelson Labs Global Segment Director, Pharmaceutical Microbiology, contributes an overview of filtration sterilization in aseptic processing. She and Isabel Vance, Nelson Labs Study Director III, then address certain key quality attributes. Among these are microbial retention and the testing that validates this.
Morris and Vance also look at the regulatory side of the process, and how it has changed over time.
