Performance evaluation is governed by standards published by organizations such as International Organization for Standardization (ISO), United States Pharmacopeial Convention (USP), European Directorate for Quality of Medicines (Ph. Eur.), and China National Medical Products Administration (NMPA). Key properties of a stopper are:
- Penetrability: force required to penetrate with a needle -
- Fragmentation: number of fragments released upon needle penetration (essential to understand for multi-use stoppers)
- Self-Sealing: ability to re-seal after multiple needle penetrations
- Container Closure Integrity: ability of assembled container system to protect drug product
Acceptable performance depends upon the standard considered, and the drug product for which the stopper is being used. West Analytical Lab Services has the staff, knowledge, and facility to perform evaluations according to all the standards cited, and offers testing through its Integrated Solutions platform.
