Title: PDA Technical Report 26 (TR 26): The Industry Standard for Sterilizing Filtration
In the world of pharmaceutical and biotechnology manufacturing, few documents are as critical to sterile drug production as PDA Technical Report 26 (TR 26). Titled “Sterilizing Filtration of Liquids,” this document is the global benchmark for anyone involved in validation, quality assurance, and manufacturing of sterile products.
If you are looking for a detailed summary, a breakdown of its chapters, or guidance on how to access the PDA Technical Report 26 PDF, this post covers everything you need to know.
Impact of pressure, flow rate, temperature, and time on filter performance.
The report outlines the requirements for validating that a filter can retain a specific bacterial challenge (usually Brevundimonas diminuta). It discusses how to validate filters for "worst-case" scenarios and the importance of product-specific validation.
Records required for regulatory submission (NDA, BLA, ANDA). Any change in filter supplier, pore size, or process requires revalidation.
