1. A coated glass pharmaceutical package comprising:
a glass body having a Type 1 chemical durability according to USP 660, at least a class A2 base resistance or better according to ISO 695, and at least a type HGB2 hydrolytic resistance or better according to ISO 719, the glass body having an interior surface and an exterior surface and a wall extending therebetween;
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, wherein:
the portion of the exterior surface of the coated glass package with the lubricous coating has a coefficient of friction that is at least 20% less than an uncoated glass package formed from the same glass composition and the coefficient of friction does not increase by more than 30% after undergoing a depyrogenation cycle comprising exposure to a temperature of 250° C. for a time period of 30 minutes; and
a horizontal compression strength of the coated glass package is at least 10% greater than an uncoated glass package formed from the same glass composition and the horizontal compression strength is not reduced by more than 20% after undergoing the depyrogenation cycle comprising exposure to a temperature of 250° C. for a time period of 30 minutes and then being abraded,
wherein the lubricous coating comprises a polymer.
