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.
