USP 381

Understanding USP 381 and Its Role in Pharmaceutical Packaging USP 381 defines the performance requirements for elastomeric closures used in injectable drug packaging. These closures must maintain container integrity while allowing repeated needle access without compromising sterility. The standard focuses on three critical functionality evaluations: penetrability, fragmentation, and self-sealing capacity. Pharmaceutical manufacturers and quality control teams rely on USP 381 to ensure closures perform consistently during clinical use. Failures in these parameters can lead to contamination, dosage inaccuracies, or patient safety risks. Therefore, laboratories must implement precise and repeatable testing procedures aligned with the standard.
