A method for providing a saccharide based lubricating or protective coating or layer on a substrate surface is provided. In particular, a lubricity and/or protective coating or layer made by said method is provided. Pharmaceutical packages or other vessels coated by said method and the use of such pharmaceutical packages or other vessels protecting a compound or composition contained or received in said vessel with a protective coating against mechanical and/or chemical effects of the surface of the vessel without a protective coating material are also provided.
1. A filled package comprising: a vessel having a lumen defined at least in part by a wall, the wall having an interior surface facing the lumen and an outer surface; a barrier coating of SiOx, wherein x is from 1.5 to 2.9, from 2 to 1000 nm thick, the barrier coating of SiOx having an interior surf
1. A filled package comprising: a vessel having a lumen defined at least in part by a wall, the wall having an interior surface facing the lumen and an outer surface; a barrier coating of SiOx, wherein x is from 1.5 to 2.9, from 2 to 1000 nm thick, the barrier coating of SiOx having an interior surface facing the lumen and an outer surface facing the wall interior surface, the barrier coating being effective to reduce the ingress of atmospheric gas into the lumen compared to an vessel without a barrier coating; a protective coating of a saccharide, the protective coating of a saccharide having an interior surface facing the lumen and an outer surface facing the interior surface of the barrier coating, the protective coating of a saccharide being effective to increase the calculated shelf life of the package (total Si/Si dissolution rate); and a fluid composition contained in the lumen and having a pH between 5 and 9; wherein the calculated shelf life of the package is more than six months at a storage temperature of 4° C. 2. The filled package of claim 1, in which at least a portion of the wall of the vessel comprises: a polyolefin, a polyester or a combination of a polyolefin and a polyester. 3. The filled package of claim 1, in which at least a portion of the wall of the vessel comprises or consists essentially of a member selected from the group consisting of: a cyclic olefin polymer, a cyclic olefin copolymer, polypropylene, a polyester and polyethylene terephthalate. 4. The filled package of claim 1, in which the vessel comprises a syringe barrel or a vial. 5. The filled package of claim 1 in which the protective coating of a saccharide further comprises a coupling agent linking the protective coating of a saccharide to the SiOx barrier coating. 6. The filled package of claim 5, in which the protective coating of a saccharide is a sugar that is a sorbitan or comprises hyaluronic acid. 7. The filled package of claim 5, in which the coupling agent has a functionality reactive with a saccharide hydroxyl functional group. 8. The filled package of claim 5, in which the coupling agent comprises a member selected from the group consisting of: a silane functional group that interacts with an SiOx barrier layer, trimethoxysilylpropyl isocyanate, and 3-Aminopropyltriethoxysilane (APTES). 9. The filled package of claim 1, in which the protective coating of a saccharide contacting the fluid composition is between 10 and 1000 nm thick two years after the filled package is assembled. 10. The filled package of claim 1, in which the rate of erosion of the protective coating of a saccharide, if directly contacted by a fluid composition having a pH of 8, is less than 20% of the rate of erosion of the barrier coating, if directly contacted by the same fluid composition under the same conditions. 11. The filled package of claim 1, in which the rate of erosion of the protective coating of a saccharide, if directly contacted by a fluid composition having a pH of 8, is from 5% to 20% of the rate of erosion of the barrier coating, if directly contacted by the same fluid composition under the same conditions. 12. The filled package of claim 1, in which the protective coating of a saccharide is at least coextensive with the barrier coating. 13. The filled package of claim 1, having a shelf life, after the filled package is assembled, of at least two years, in which the shelf life is determined at 4° C. 14. The filled package of claim 1, having a shelf life, after the filled package is assembled, of at least two years, in which the shelf life is determined at 20° C. 15. The filled package of claim 1, in which the fluid composition removes the protective coating of a saccharide at a rate of 1 nm or less of thickness per 44 hours of contact with the fluid composition. 16. The filled package of claim 1, in which the protective coating of a saccharide is effective to provide a lower frictional resistance than the uncoated interior surface, wherein the frictional resistance is reduced by at least 25% in comparison to the uncoated interior surface. 17. The filled package of claim 16 which is a syringe comprising a syringe barrel and a plunger and the wall defines at least a portion of the syringe barrel, in which the protective coating of a saccharide is effective to reduce the frictional resistance between the wall and the plunger at least two years after the filled package is assembled. 18. The filled package of claim 1, in which the silicon dissolution rate by a 50 mM potassium phosphate buffer diluted in water for injection, adjusted to pH 8 with concentrated nitric acid, and containing 0.2 wt. % polysorbate-80surfactant from the vessel is less than 170 ppb/day. 19. The filled package of claim 1, in which the total silicon content of the protective coating of a saccharide and barrier coating, upon dissolution into 0.1 N potassium hydroxide aqueous solution at 40° C. from the vessel, is less than 66 ppm. 20. The filled package of claim 1, in which the calculated shelf life (total Si/Si dissolution rate) is more than 2 years.
