A container for retaining a fluent therapeutic has a fluid transfer tube having a proximal end in fluid communication with an interior space of the container, a distal end accessible outside of the container and an inner surface defining a flow passage through which fluent therapeutic is delivered from the interior space of the container. At least a portion of the tube inner surface is textured such that the inner surface has a surface roughness equal to or greater than about 20 microinches. In a method for making such a container, the fluid transfer tube is extruded from an extruder and its inner surface is textured to have a surface roughness equal to or greater than about 20 microinches. The tube is secured to the container with a proximal end in fluid communication with the interior space of the container and a distal end accessible outside of the container.
