Sciele Pharma, Inc., has introduced the Adrenaclick, a single-dose epinephrine auto-injector for emergency treatment of anaphylaxis.  It is available as a single unit or two pack, with two dosing options (0.15 mg or 0.3mg).

At first glance of the company's video demo, the device looks similar to a TwinJect, so it appears there is no practical size advantage over the existing Epipens and TwinJect.
