  • PHARMACEUTICAL CONTAINER AND LIQUID COMPOSITION
    Publication number: 20230201464
    Abstract: A pharmaceutical container for drug delivery includes a barrel configured to slidably receive a stopper, the stopper having a proximal end suitable for contacting a plunger rod and a distal end suitable for contacting a pharmaceutical composition, the stopper having a circumferential surface partially contacting an inner surface of the barrel, a surface roughness of the inner surface of the barrel declines from the stopper's start position to its end position by at least 3% of at least one of Ra roughness or Rms roughness, the inner surface of the barrel having a surface roughness Ra of less than 100 nm.

  • Pharmaceutical container and liquid composition
    Patent number: 11426521
    Abstract: A pharmaceutical container for drug delivery includes a barrel configured to slidably receive a stopper. The container exhibits a ratio of a break loose force (BLF) relative to a glide force (GF) of BLF/GF?2 during a break loose and glide force test and a total glide force variation TGFV=GFmax?GFmin measured when the stopper is moved from a start position to its end position is TGFV<2 N.
