| Gain a comprehensive understanding of Container Closure Integrity Testing (CCIT), an essential quality assurance practice for pharmaceutical and medical device packaging. This overview explores the fundamental concepts behind CCIT, explaining why maintaining a sterile barrier is critical to product safety, efficacy, and shelf life. It outlines key testing principles, including deterministic and probabilistic methods used to detect leaks and package defects. The description also addresses global regulatory expectations and guidance that influence CCIT strategy, validation, and routine testing. Designed for professionals across development, validation, and manufacturing, this overview highlights how CCIT supports regulatory compliance, risk mitigation, and consistent protection of sterile products throughout their lifecycle. |
