Claim 9:
10. A coated borosilicate glass pharmaceutical package comprising:
a body formed from a borosilicate glass body having a Type 1 chemical durability according to USP 660, the body having an interior surface and an exterior surface and a wall extending therebetween; and
a lubricous coating having a thickness of less than or equal to 90 nm positioned on at least a portion of the exterior surface but not on any portion of the interior surface, the lubricous coating comprising a polymer, wherein:
the portion of the exterior surface of the coated borosilicate glass pharmaceutical package with the lubricous coating has a coefficient of friction of less than or equal to 0.6 relative to a like-coated borosilicate glass pharmaceutical package formed from the same glass composition after a depyrogenation cycle comprising exposure to a temperature of 250° C. for a time period of 30 minutes; and
a light transmission through the portion of the exterior surface of the coated borosilicate glass pharmaceutical package is greater than or equal to about 55% of a light transmission through an uncoated borosilicate glass pharmaceutical package formed from the same glass composition for each wavelength from about 400 nm to about 700 nm after the depyrogenation cycle.
