Abstract:
Glass pharmaceutical packages comprising glass containers are disclosed. In embodiments, a coated glass pharmaceutical package includes a glass container formed from one of a borosilicate glass composition that meets Type 1 criteria according to USP or an alkali aluminosilicate glass having a Class HGA 1 hydrolytic resistance when tested according to the ISO 720-1985 testing standard. A lubricous coating may be positioned on at least a portion of the exterior surface of the glass container. The portion of the coated glass pharmaceutical package with the lubricous coating has a coefficient of friction that is at least 20% less than an uncoated glass container formed from the same glass composition. A horizontal compression strength of the portion of the coated glass pharmaceutical package with the lubricous coating may be at least 10% greater than an uncoated glass container formed from the same glass composition.
