Antares Pharma, Inc. (Antares) is a specialty pharmaceutical Company that focuses on developing and commercializing self-administered parenteral pharmaceutical products and technologies. The Company develops and manufactures for itself and with partners, pressure-assisted injectors, with and without needles, which allow patients to self-inject drugs. It has developed variations of the needle-free injector by adding a small shielded needle to a pre-filled, single-use disposable injector, called the Vibex pressure assisted auto injection system. This system is an alternative to the needle-free system for use with injectable drugs in unit dose containers and is suitable for branded and generic injectables. It has also developed a disposable multi-dose pen injector for use with standard cartridges.
