Description

Stable pharmaceutical formulations and methods of making same are provided. In a general embodiment, the present disclosure provides a method of making a stable pharmaceutical formulation comprising adding one or more vitrifying additives to an aqueous pharmaceutical solution to raise the glass transition temperature of the aqueous pharmaceutical solution. The aqueous pharmaceutical solution can be cooled to a temperature of about -50 C to about -10 C. The vitrifying additive enhances the formation of a glass or amorphous solid of the aqueous pharmaceutical solution at cryogenic temperatures (-50 to -10C), and the pharmaceutical formulation can be thawed to liquid form and administered to a mammalian subject.

La présente invention concerne des formulations pharmaceutiques stables, et des procédés de fabrication correspondants. Un mode de réalisation général de la présente invention concerne un procédé de fabrication d'une formulation pharmaceutique stable en ajoutant à une solution pharmaceutique aqueuse un ou plusieurs additifs vitrificateurs de façon à augmenter la température de transition vitreuse de la solution pharmaceutique aqueuse. La solution pharmaceutique aqueuse peut être refroidie jusqu'à une température se situant dans une plage d'environ -50°C à -10°C. L'additif vitrificateur améliore la vitrification ou la solidification amorphe de la solution pharmaceutique aqueuse à des températures cryogènes (-50°C à -10°C), la formulation pharmaceutique pouvant se liquéfier par décongélation et s'administrer à un sujet mammifère.
