Zusammenfassung:A cartridge is configured to receive an injectable drug. The cartridge includes a body, and the body includes a proximal end portion having a proximal opening, a distal end portion having a distal opening, and a bore coupling the proximal opening and the distal opening. The cartridge further includes a pierceable septum coupled to the distal opening and a plunger movably carried within the bore. A volume is disposed in the bore between the pierceable septum and the plunger. The volume has a reduced pressure, and the reduced pressure is less than atmospheric pressure. A stopper is detachably coupled to the distal opening.
