Particle Management in Single-Use Systems

 

Introduction

Particles management for single-use systems (SUS) is not always an obvious consideration. There are currently no standards or regulations directly applicable to SUS. The specification for the SUS used in a pharmaceutical process must be derived from the regulations applicable to the drug product in its final container. Here is a list of what Pall Biotech feels are the most important regulations and guidance documents on this topic. These references provide deeper insight and help to understand the main elements of this complex and evolving subject in more detail. 

 

Regulations Applicable to the Drug Product in its Final Container 

1. International Council for Harmonization of Technical Requirements for Pharmaceuticals for Human Use (ICH) Q4B Annex 3(R1) Test for Particulate Contamination: Sub-Visible Particles General Chapter. 

2. European Pharmacopoeia (EP) general chapter 2.9.19. Particulate Contamination: sub-visible particles. 

3. EP, 2.9.20. Particulate Contamination: visible particles. 

4. Japanese Pharmacopoeia (JP), 6.07 Insoluble Particulate Matter Test for Injections. 

5. United States Pharmacopeia (USP) <788> Particulate Matter in Injections. 

6. USP <790> Visible Particulates in Injections. 

7. USP <1790> Visual Inspection of Injections.
