Cartridges are provided for storing and facilitating the delivery of pharmaceutical formulations. In one preferred embodiment, the cartridge comprises a body including a bore extending through the body, and a plunger movable disposed in the bore. The bore has a transverse dimension at a distal end that is equivalent to that at a midpoint. The plunger has a planar contact surface that is transversely coextensive with the bore for applying a force to a pharmaceutical formulation contained in the bore. This configuration helps to eliminate dead volume, and therefor enables filing by volume rather than weight to ensure accurate dosing
