Methods are disclosed for enhanced terminal sterilization of packaged, pre-filled syringes containing drug solutions. The methods utilize a sequence of autoclave steps - including vacuum application, dynamic steam pulsing, and controlled counterpressure - to sterilize both the syringe and its enclosing semipermeable pouch without compromising structural integrity or drug quality. The vacuum removes air from the secondary7 space within the pouch, while steam pulsing ensures thorough penetration. Counterpressure is applied to prevent plunger movement caused by internal expansion. The process concludes with drying and cooling phases. The methods maintain sterility to a sterilization assurance level (SAL) of 10 6 and are suitable for use with a range of syringe and packaging materials. The resulting product is sterile field ready, single-use compliant, and structurally intact. These techniques are adaptable to various sterilization times and temperatures, ensuring flexibility across drug formulations and syringe configurations.
