Pda Technical Report 27 Pdf -

Implementing in-process controls (e.g., capping force and crimp evaluations) alongside physical leak testing to ensure manufacturing equipment does not compromise seal integrity.

Selecting the right materials (glass, plastics, elastomers) and designing the closure system.

The report emphasizes that integrity is not just a one-time test at the end of production. It must be considered throughout the product lifecycle: pda technical report 27 pdf

| Term | Definition per TR 27 | |-------|----------------------| | | The ability of a container-closure system to prevent loss of product, entry of microorganisms, and ingress of gases/vapors (e.g., oxygen, moisture). | | Maximum Allowable Leakage Limit (MALL) | The largest leak that still ensures sterility; derived from microbial ingress studies (e.g., ~0.2–5 μm for most sterile products). | | Leak | An unintended passage through the container-closure system. | | Deterministic Method | A test that physically measures a leak (e.g., pressure decay, vacuum decay, tracer gas). | | Probabilistic Method | A test that relies on the probability of a dye or microbial challenge entering a leak (e.g., dye ingress, microbial immersion). |

Within the report, methods are categorized by their reliability: Implementing in-process controls (e

The report categorizes testing methods into two main groups:

TR 27 has significantly influenced regulatory expectations from the and EMA regarding sterile drug quality. By emphasizing science-based validation over simple "pass/fail" end-product testing, it has helped the industry reduce risks associated with contamination, which remains a leading cause of parenteral drug recalls.
