The dye ingress test method continues to be a widely used test method for Container Closure Integrity (CCI) within the pharmaceutical industry. For high risk parenteral applications this method is not a suitable approach due to reliability of the method and measure. For applications with large molecule drugs or for prefilled injectable container formats, the use of a dye ingress test method will simply not work. There is an active campaign to understand all the dynamics and implications of deploying a CCI test method. The transition to a deterministic test method for high risk CCI applications is a matter of common-sense patient safety.
