How to Qualify Container Closure Systems for Compounding Pharmacy (503Bs)

We are pleased to announce our recent publication in the November/December 2019 Issue of the International Journal of Pharmaceutical Compounding. In the article “How to Qualify Container Closure Systems, Part 1,” we address how compounding pharmacies (503Bs) can qualify systems for intended use via container closure integrity (CCI) to meet FDA Guidance requirements.1

The FDA Guidance requires container closure systems be tested for integrity under appropriate storage conditions and beyond the desired beyond-use date (BUD).2 The article breaks down the USP <1207> concept of maximum allowable leak limit (MALL) (i.e., the smallest gap, or leak rate, that places drug product quality at risk) and methods for measuring CCI.3 CCI data can show loss of sterility, permeation of gas, or loss of vacuum due to defects in container closure systems. Assessing CCI data against MALL and drug product critical sensitivities can establish whether container closure systems can provide required performance over drug BUD at required storage conditions, i.e. intended use. Our article shows representative CCI data on vial systems, along with the benefits and other type of information gleaned from different CCI methods.

West can guide 503Bs through the agency and compendia requirements. West’s Integrated Solutions strategy can help Simplify the Journey™ for customers by taking the guesswork out of designing and executing CCI studies.
