Biodel’s glucagon device speeds the preparation process for lifesaving glucagon — and minimizes confusion. Traditional glucagon kits require users to inject liquid from a syringe into a vial of glucagon powder, shake the vial until the liquid turns clear, and withdraw the liquid into the syringe before injecting. Biodel’s innovative glucagon pen cuts the complex instructions by more than half. Here’s how it works: twist the body of the pen to mix the powder and liquid held inside, remove the needle shield, inject, and press the plunger to deliver the dose. The needle automatically retracts once glucagon is delivered. Biodel plans to file for FDA approval of the device in 2015.
