A low-friction thermally stable coating having a thickness of .ltoreq.1 .mu.m may be positioned on at least a portion of the exterior surface. The low-friction coating may comprise a silane. The portion of the exterior surface of the coated pharmaceutical package may have a coefficient of friction that is at least 20% less than an uncoated pharmaceutical package formed from the same borosilicate glass composition.
