Abstract
The prefilled syringe filled with a drug in advance, leaking of liquid from the cap is prevented, gas barrier properties are given to the whole of the barrel filled with the drug and the shoulder section so that degradation of the drug is prevented, permeation of microbial contaminants is prevented to a high extent, and efficiency of packing as a compact container can be increased. The prefilled syringe includes a guard-shaped extension projecting from the outer periphery of a shoulder section of the syringe barrel on the nozzle side, and a range from a part where a gasket of the plunger is positioned on the outer surface of the syringe barrel filled with the drug to the guard-shaped extension is covered with barrier packaging.
