Emulsions inverses stables à forte concentration en composé(s) fluoré(s) et leur utilisation pour l'administration pulmonaire de médicaments et pour la fabrication d'émulsions multiples.

摘要

Stable reverse water-in-fluorocarbon emulsions and water-in-fluorocarbon-in-water multiple emulsions comprising the reverse fluorocarbon emulsions. The reverse emulsions comprise a continuous phase which is a highly fluorinated or perfluorinated compound, a discontinuous aqueous phase and a fluorinated surfactant or mixture of surfactants. The multiple emulsions comprise an aqueous continuous phase and a discontinuous phase comprising globules formed of aqueous droplets dispersed into a highly fluorinated or perfluorinated compound. The emulsions can contain pharmacologically active agents, and are particularly suitable for pulmonary drug delivery.
