A pharmaceutical container for drug delivery includes a barrel configured to slidably receive a stopper. The stopper has a proximal end suitable for contacting a plunger rod and a distal end suitable for contacting a pharmaceutical composition. The stopper has 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.

Pharmaceutical container and liquid composition

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&#x2264;2 during a break loose and glide force test and a total glide force variation TGFV=GF&#x2212;GFmeasured when the stopper is moved from a start position to its end position is TGFV&#x3c;2 N.
