The pharmaceutical industry is shifting toward pre-filled syringes (PFS) as the optimal delivery system for many drug products. The utility of a syringe system is dependent upon its ability to maintain good container closure integrity (CCI) through drug product shelf life.
CCI failure presents a risk to patient safety – thus the ability to measure CCI is critical. USP <1207> (Package Integrity Evaluation – Sterile Products) endorses several deterministic methods; one of which, high-voltage leak detection (HVLD), is very well suited to syringe systems. HVLD equipment operates by moving a high-voltage probe along the length of a syringe; a defect (as small as 2 microns) usually results in a visible discharge through the fluid in the syringe system, however the position of the defect is always recorded.
HVLD can be useful for detecting a defect between the syringe body and plunger. West has full capability to measure CCI by HVLD, including a state-of-the art system suitable for polymer-based syringe systems with non-conductive fluids. This capability includes development and validation of a unique method for each syringe/drug system.
The scientists at West are available to help customers determine how HVLD can best serve them – from study design through execution – to ensure that West syringe components and customer drug products combine to fully meet the goal of patient safety.
