Many medical conditions require chronic treatment with subcutaneous injectable biologics often exceeding 1.0 mL. However, subcutaneous administration of volumes of 2.0 mL or greater using a standard needle and syringe or auto-injector proves challenging, and patients often must administer two separate injections to achieve their full dose or endure injection times in excess of 10 s if using a mechanical autoinjector. In addition, needle-based injections often cause patient anxiety and discomfort. In this article, we describe an approach to meet these needs with a needle-free medication delivery device capable of rapidly delivering up to 2.0 mL with minimal discomfort. A pilot study was conducted with this needle-free injection system to evaluate the delivery of a 2.0 mL volume in human subjects. The results demonstrated that injections of up to 2.0 mL were well tolerated and often preferred over two separate 1.0 mL injections using the needle-free injection system. |
