Abstract

In one aspect, a self-lubricating component is provided for a pharmaceutical packaging assembly. The self-lubricating component comprises a polymer composition and an effective amount of a lubricating additive such as, for example, boron nitride. In another aspect, a pharmaceutical packaging assembly may be provided having a surface thereof coated with a lubricating composition comprising boron nitride. The pharmaceutical packaging composition may be, for example, a pre-filled syringe comprising a body (barrel) and a plunger assembly.
