Drawing from West’s deep elastomer formulation expertise and using QbD principles, the development of the 4040/40 elastomer formulation was focused on raw material selection to make significant progress in mitigating the risk of particulates, extractables& leachables, and fragmentation & coring.

4040 LyoTec® components provide confidence you have chosen a high-performing primary packaging product, de-risking your new drug from development through patient administration.
