PACKAGE FOR PHARMACEUTICAL FORMULATION

摘要

Cartridges (10) are provided for storing and facilitating the delivery of pharmaceutical formulations. In one preferred embodiment, the cartridge comprises a body (20) including a bore (30) extending through the body (20), and a plunger (60) movably disposed in the bore (30). 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 (62) that is transversely coextensive with the bore (30) 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.
