Lyophilization (also called freeze drying) is the process of dehydrating a material at low temperature and reduced pressure. It is used to extend the shelf life of many biologic drug products. Absent water, drug metabolic degradation processes are greatly reduced. Clearly, it is crucial to know the water content of elastomer stoppers for vial-based primary packaging systems for lyophilized drug products.

West Pharmaceutical Services’ elastomeric formulations for injectable packaging components for vials and syringes may contain Dry Natural Rubber (DNR) in the form of crepe, but the formulations do not incorporate NRL.
