Abstract

Provided herein is a method for manufacturing a prefilled syringe. The method includes providing a prefilled syringe including a syringe barrel defining a chamber containing a fluid therein and a stopper axially sealing the fluid in the chamber, with the stopper including one or more ribs forming a sealing surface with the syringe barrel. The method also includes performing a terminal steaming process on the prefilled syringe, with the terminal steaming process including a first steaming cycle that exposes the syringe to steam at a set temperature and a set pressure and a second steaming cycle that exposes the syringe to steam at the set temperature and the set pressure. Performing of the terminal steaming process reduces a diameter of at least one rib of the one or more ribs, to reduce a contact pressure between the stopper and the syringe barrel.
