  • Publication number: 20090169635
    Abstract: Colloidal compositions, loaded with non-covalently bonded antibiotics, can be efficiently used for the treatment of severe bacterial pneumonia and other serious lung infections such as tuberculosis. Such formulations, comprised of biodegradable nanoparticles or nanocapsules with incorporated antibiotics, show a significant increase in antibacterial activity, extended and sustained drug release and a decrease in frequency of the drug administration. Antibiotics of various types, such as aminoglycosides, glycopeptides and others can be successfully incorporated into a nanoparticulate colloidal delivery system.

  • Publication number: 20080149521
    Abstract: A method of packaging of azithromycin which provides improved stability of azithromycin upon storage. Additionally, 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.
