As drug manufacturers aim for higher safety standards and enhanced patient care, controlling the drug product at the point-of-use in a hospital or clinical environment remains a significant challenge. The method of vial access often varies, increasing the risk of adverse patient outcomes, such as stopper cores or fragments entering the drug product. If injected, these fragments can lead to cardiovascular events and other complications. Several factors contribute to stopper coring and fragmentation in the field, primarily influenced by the technique of the practitioner and the properties of the elastomeric closure.

Use of Vial Adapters Can Reduce Drug Overfill

By Fabrice Berthelot

January 22, 2018

Vial adapters are easy to use and pose less risk of needlestick injury than traditional syringe and needle manipulation. They not only provide needle-free transfer of liquid for reconstitution, but also enable consistent withdrawal of drug product from a vial. By providing such consistent withdrawal, the use of vial adapters can aid in reducing the amount of required overfill (extra drug product in a vial to address the fact that not all drug product can be removed), which may result in cost savings.
