Abstract
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.
