Container-content interactions with radiopharmaceuticals: Seeing is believing.

This perspective article addresses the critical issue of container-content interactions in the administration of intravenous medications, with a focus on radiopharmaceuticals used in nuclear medicine. Medication administration errors pose a significant challenge to patient safety. The "five rights" framework-ensuring the right patient, drug, time, dose, and route-serves as a cornerstone for safe drug administration. In the context of radiopharmaceuticals, notable for their use in nuclear medicine, adherence to these principles is paramount due to their unique properties and role in diagnostic and therapeutic procedures. The article explores the impact of container materials, particularly in syringes, on radiopharmaceutical stability and administration accuracy. It delves into the complexities of sorption phenomena, highlighting studies demonstrating its occurrence and potential consequences, including variations in administered doses and compromised diagnostic or therapeutic outcomes. Noteworthy factors influencing sorption include the type of radiopharmaceutical, container composition, molecular properties, and dilution. Findings revealing residual activity in syringes and identifying specific components, such as lubricants, silicon gaskets, and plungers, contributing to adsorption are presented. Migration of metal contaminants from container to content is discussed, emphasizing the potential impact on radiochemical yield and stability. There is a need for comprehensive studies to characterize drug-container interactions and poses crucial questions about the true benefit patients derive from prescribed activities. It challenges current practices, suggesting a need for tailored activity levels, container validation protocols, and rigorous testing of hospital preparations. Ultimately, this perspective paper calls for a deeper understanding of these interactions, urging regulatory consideration and standardization to ensure optimal drug administration and patient outcomes.
