An auto-injector is a drug delivery system designed to deliver a single dose of a drug typically ≤1mL fill volume. Most auto-injectors perform like spring-loaded syringes. By design, auto-injectors are easy to use and are intended for self-administration by patients, or administration by untrained personnel. Auto-injectors were initially designed to overcome the hesitation associated with self-administration of the pre-filled syringe. With a spring loaded auto-injector, the patient does not have control over the injection rate, which at times can cause increased injection site pain during administration. An example of this issue reported from one patient is provided below.
“I tried auto-injectors and the pain was INTENSE to say the very least. It was already painful enough from the pre-filled syringe but the auto-injector does the whole injection in just 15 seconds and for me, that much medicine going into my subcutaneous fat is uncomfortable just from the sheer volume of it, let alone the horrible sting.”
A new injector technology option, the SelfDose® self-injector system provides an integrated drug delivery solution that is manually controlled to minimize discomfort. Furthermore, the integrated safety system helps mitigate the risk of accidental needlestick injuries.
West and one of its pharmaceutical partners conducted multiple human factors studies that reported very favorable results with high scores for “ease of administration,” “confidence of a complete injection without pain” and “satisfied with the injector system.” The following are reported statements from patients, healthcare practitioners and caregivers:
