Designing Disposable Single Use Filling Lines for Minimizing Losses and Maximizing Yield

The advent of ready to use single use filling line has revolutionized the fill-finish process for sterile injectables, enabling faster product changeovers and reducing risks related to cleaning validation and cross-contamination. However, concerns remain around E&L, particulate contamination, variable fills, adsorption, and product loss, especially with high-value drugs.

These challenges can be addressed by careful material selection, Efficient design, and monitoring and Control of Particulate Matter during manufacture of these complex single use systems.

Careful Selection of Materials

Careful selection of single-use components with low extractables is crucial to minimize leachable risks, avoiding costly redesigns and delays. At MDI, our advanced analytical labs offer extractables profiling and toxicological assessments to identify target leachables. To address product loss from adsorption, especially in low-volume or high-value drug; we provide validation services to evaluate component compatibility and recommend surface modifications or material change, or flush volumes to ensure label claim compliance.

Barrier filters that simplify PUPSIT by supporting both liquid and air passage

Final sterile filtration is the subject of intense regulatory attention in the pharmaceutical and biopharmaceutical industries. According to EU Annex 1 2022 PUPSIT of final sterilizing grade filter is one of the requirements, additionally almost all other regulatory agency insist on using redundant filtration system.

Following these regulatory guidelines makes the filtration and filling process challenging and assembly more complex. While performing PUPSIT, wetting the filters, conducting integrity test, reducing product loss, maximizing product recovery, maintaining sterility of downstream side of the filter, in some specific cases eliminating drug product dilution and drying of filter are challenges. AseptiCap® VK Barrier filters simplify PUPSIT of Redundant filtration assembly by supporting both liquid and air passage.
