An improved cartridge for the packaging of a pharmaceutical, and preferably a radiopharmaceutical, comprising a low UV-absorbing plastic barrel, closed at one end by a cap and at the other end by a piston. Said cap is provided at least partly with: a shoulder cooperating with the barrel in a double-level snap-on system; a cavity to cooperate with an elastomeric protection sleeve of an injection means fitting, to make a seal, said cap being terminated at a first end by a peel-off porous liner covering said cavity; a first plurality of radial fins protruding inside said cavity, for screwing the injection means fitting and with a second plurality of radial fins protruding on the outside of the cap to ensure fixation of the cap into a cartridge protection shield; a second end opposite to the first end, shaped so that to minimize a shadow area in the case of UV flash lamp sterilization and to ensure sufficient clearance for inserting a spike of the injection means, said second end having a reduced wall thickness for acting as a septum intended to be pierced by said spike at the time of setting up for dispensing the pharmaceutical to a patient; an external cylindrical zone at this second end to ensure leak tightness between the cap and the barrel.
