|Title:||Aqueous ophthalmic formulations and methods for preserving same|
|Abstract:||Stabilized chlorine dioxide is a preservative for ophthalmic formulations. The stabilized chlorine dioxide, when employed as a preservative ophthalmic formulations is preferably present in an amount of from about 0.0002 or about 0.002 to about 0.02 weight/volume percent. The aqueous ophthalmic formulations, in addition to the stabilized chlorine dioxide and the water which functions as a vehicle for the formulations, contains an ophthalmically acceptable tonicity component effective to maintain the osmolality of the formulation at least about 200 mOsmol/kg, and a buffer to maintain the pH of the ophthalmic formulation within an acceptable physiological range. A method for preserving aqueous ophthalmic formulations utilizing stabilized chlorine dioxide is also set forth.|
