Abstract
A reduced-dissolved-oxygen-content drug solution produced by filling and sealing the drug solution in a drug solution container () formed of a plastic material having an oxygen permeability of not lower than 200 cm/m·24 h·atm at 25° C. at 60% RH within 12 hours after a steam sterilization process or a hot water sterilization process and having a steady-state oxygen permeability of not higher than 100 cm/m·24 h·atm at 25° C. at 60% RH, subjecting the drug solution container to the steam sterilization process or the hot water sterilization process, and storing the drug solution container in an environment having deoxidization means for reducing the dissolved oxygen concentration of the drug solution to not higher than 2 ppm when the oxygen permeability of the plastic material reaches the steady-state level.
