Abstract
A method of sterilizing a prefilled syringe comprises assembling a syringe assembly and performing at least one ethylene oxide (EtO) sterilization procedure cycle. The assembling step includes inserting a tip cap at a first end of a plunger, filling a non-glass barrel with sterilization sensitive material at a second end of the barrel, and inserting the plunger into the barrel at a second end to seal the sterilization sensitive material within the barrel. The EtO sterilization procedure cycle comprises undergoing a preprocessing stage, a wash and conditioning stage, an EtO sterilization stage and a wash and post exposure stage. Upon completing the EtO sterilization procedure cycle, a resultant pH of the sterilization-sensitive material does not exceed an acceptable pH range as defined by the United States Pharmacopeia. The disclosure also discusses inserting an assembled prefilled syringe into a procedure tray prior to performing the EtO sterilization procedure cycle.
