Mitigate risk of chemical and physical deterioration of plungers


West Pharmaceutical Services, a manufacturer of systems and components for injectable drug administration, has announced a new line of steam-sterilised plungers for prefillable glass syringes.

The Westar Ready-to-Use (RU) steam-sterilised plungers can mitigate risk of chemical and physical deterioration of plungers through a steam sterilisation cycle that can minimise impact on the elastomer’s physical characteristics and on chemical oxidation and degradation during the plungers’ shelf life, the Lionville, PA, US-based firm says.

The new plungers can also decrease the number and lower the levels of extractables, with less potential for interaction between the plunger and the drug; and improve the function of the prefilled syringe due to lower and more consistent break loose forces.

The Westar RU steam sterilisation process is fully validated and supported by West’s technical and regulatory expertise.

Plungers are available from West and its long-time partner, Daikyo Seiko. They fit standard prefillable syringes and comply with US, European and Japanese pharmacopeias.

Particulates in parenterals

Particulate matter is a key indicator of quality for injectable drug products. Test methods are being improved with the intent to find the materials responsible for the particle(s). The desired goal of zero defects is not a workable acceptance criterion for visible particulate matter because of current packaging components and processing capabilities. The value of vision inspection systems for elastomeric primary components is shown to mitigate the risk of particulates in finished parenteral drug products.

Avoiding glass delamination

Contamination with glass flakes caused by delamination of the internal finish of container closure systems or prefilled syringes has caused numerous drug recalls. Surface imperfections and aggressive drug components can lead to interaction between product and container, resulting in leaching, dissolution, ion exchange and formation of precipitants or particles; use of cyclic olefin polymers as an alternative to glass can avoid these issues
