Container closure integrity (CCI) testing of intravenous (IV) bags is an important quality control measure to ensure the safety and efficacy of the products. CCI testing helps verify that the container closure system, including the bag and its closure, maintains its integrity throughout the product's shelf life and prevents any leakage or contamination.

Various methods, including visual inspection, dye immersion testing, bubble emission testing, headspace gas analysis, and Vacuum decay testing can be employed to assess the integrity of the container closure system. These methods help to identify any defects or breaches that may compromise the sterility and stability of the IV bags. Manufacturers should select an appropriate method based on their specific requirements and regulatory guidelines to ensure the quality and safety of the IV bags.

Vacuum Decay Technology for CCI Testing of Intravenous Bags

Vacuum decay technology is an FDA-approved leak detection technique that can be used for CCI testing of high-risk package applications. The non-destructive nature of the process allows for greater understanding of packages, testing at a greater frequency with more accuracy and with less waste. Vacuum decay technology is capable of detecting leaks in sealed rigid, semi-rigid and flexible packaging made of non-porous or porous materials and has been proven to provide repeatable, reliable and quantitative test results.

VeriPac testing systems using Vacuum decay leak testing are highly effective for leak testing of IV bags. Using a differential pressure transducer leak test system, the test method is capable of detecting package leaks and invisible defects in the IV bag body and also in seams, welds and port areas. This method is non-invasive, non-subjective and does not require sample preparation.

The test method works by connecting the VeriPac test systems to a manually operated test chamber containing an IV bag. The next step is to draw a vacuum on the IV bag in the test chamber and observe any changes in the vacuum level. If there is any damage to the package, air or liquid will flow from the package into the chamber, causing pressure fluctuations. On the other hand, defect-free packages do not leak any pressure into the chamber, keeping the chamber vacuum level constant. Regardless of the location of the defect, the vacuum decay system can pick up both large and small defects. It takes about 30 seconds for testing IV bags, repeatable and sensitive to 15 microns for liquid and gas leaks.

• ASTM Test Method F2338, FDA Consensus Standard and referenced in USP 1207 Guidelines.
• Meets Annex 1 regulatory guidelines.

Recent regulatory changes have shifted requirements and strategies for container closure integrity. IV bags and flexible parenteral presentations have experienced the greatest impact from these new perspectives on quality. IV bags have always presented a significant risk. New provisions to Annex 1 have made the requirements for quality risk management (QRM) clear, and USP guidance documents outline the need for greater control. Based on the regulatory requirements and guidance, practical solutions for IV bag container closure integrity should offer non-destructive, practical and deterministic approaches to assure integrity. There are critical considerations for IV bag QRM, and strategic approaches to assuring integrity of IV bags and flexible parenteral presentations to satisfy the shifting regulatory environment.
