Blow Fill Seal (BFS) and Form Fill Seal (FFS) Technology in Sterile Manufacturing

Blow Fill Seal (BFS) and Form Fill Seal (FFS) Technology in Sterile Manufacturing Know about sterile pharmaceutical production using Blow Fill Seal (BFS) and Form Fill Seal (FFS) technology. Both of these techniques are used to manufacture sterile pharmaceutical products as parenteral (LVP & SVP), infusions, ophthalmic and inhalation products. These are automated techniques to prepare sterile products. The basic concept of the FFS and BFS is to reduce the contamination by forming the container, filling and sealing in a closed sterile chamber of the machine. There is no personnel intervention to reduce the chances of the contamination during the manufacturing of sterile products. It gives more production at very low operational cost with the high assurance of sterility . Blow fill seal technology is widely used and accepted by the various pharmaceutical regulatory authorities as US-FDA and MHRA. The system is being used for over 30 years a...

High-Efficiency Particulate Air (HEPA) and Its Significance in Sterile Pharmaceutical Preparations

High-Efficiency Particulate Air (HEPA) and Its Significance in Sterile Pharmaceutical Preparations Everything about HEPA filters as pore size, leak test, DOP test and importance in sterile pharmaceutical manufacturing and analysis. HEPA filter integrity should be maintained to ensure aseptic conditions. Leak testing should be performed at installation to detect integrity breaches around the sealing gaskets, through the frames, or through various points on the filter media. Thereafter, leak tests should be performed at suitable time intervals for HEPA filters in the aseptic processing facility. For example, such testing should be performed twice a year in the aseptic processing room. Additional testing may be appropriate when air quality is found to be unacceptable, facility renovations might be the cause of disturbances to ceiling or wall structures, or as part of an investigation into a media fill or drug product sterility failure. Among the filters that should be leak tested ar...
