CA 2423201

Provided are stabilized aqueous solutions containing low concentrations of hydrogen peroxide as a preservative. Such solutions are effectively stabilized at pH > 8 by the use of certain biocompatible organophophorous compounds as chelating stabilizers. These ophthalmologically acceptable compositions are especially useful in buffered saline for eye care solutions either with or without ophthalmic medicinal agents.

L'invention concerne des solutions aqueuses stabilisées renfermant de faibles concentrations de peroxyde d'hydrogène comme agent de conservation. On stabilise de manière efficace de telles solutions à un pH supérieur à 8 en utilisant certains composés organophosphoreux biocompatibles comme stabilisants de chélation. On utilise, notamment, ces compositions acceptables sur le plan ophtalmique dans une solution saline tamponnée destinée aux solutions de soins oculaires, avec ou sans agents médicinaux ophtalmiques.
