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.

Adding Color to Your Closure Choices

By Michelle Deutsch

October 20, 2017

Color has a surprising number of uses in injectables packaging.

European guidance states that “similarity in packaging which contributes to medication error can be reduced by the judicious use of color on the pack” ¹. Draft guidance issued by the U.S Food and Drug Administration (FDA)² similarly recommends that “sponsors use color prudently to bring attention to the product name, strength, and important warning(s).” Color – when applied thoughtfully and with full awareness of the context in which the drug will be used – can be an important way for manufacturers to help practitioners and patients differentiate products and support their correct use.
