Efficacy of a Novel Prefilled Single-Use Needle-Free Device (Zeneo®) in Achieving Intramuscular Agent Delivery: An Observational Study

摘要

BackgroundIt is recognized that, as a result of variation in tissue anatomy, current auto-injectors may have insufficient needle length to achieve successful intramuscular agent delivery in a number of patients. The Zeneo^® auto-injector is a novel prefilled, single-use, needle-free device currently in development for intradermal, subcutaneous, and intramuscular agent delivery across a variety of clinical indications. We aimed to evaluate delivery depth of the device calibrated at pressure appropriate for intramuscular (IM) administration.
