Abstract
Compositions and methods of stabilizing azithromycin compositions are described. Stabilized azithromycin compositions comprise an intimate admixture of azithromycin and a stabilizing-effective amount of an antioxidant to improve the resistance of the azithromycin to degradation. Coprecipitation or co-milling of azithromycin and an antioxidant are particularly preferred means of achieving an intimate admixture. Pharmaceutical formulations comprising a stabilized azithromycin composition and methods of making such formulations are also described.
