An aqueous solution comprising a chelating agent at a concentration of about 0.1-0.5%, and an antioxidant agent at a concentration of about 0.1-0.5%, wherein the pH of the solution is between about 4.5 and about 7.5 is disclosed. The aqueous solution may comprise a tetracycline composition wherein the tetracycline is formulated in the aqueous solution. A method for reducing the rate and/or overall extent of degradation of a tetracycline in aqueous solution, comprising admixing in a tetracycline containing solution a chelating agent at a concentration of about 0.1-0.5% and an antioxidant at a concentration of about 0.1-0.5% and, as necessary, adjusting the pH of the solution so that it is between about 4.5 and about 7.5 is also disclosed. Tetracycline compositions of the invention may be used to treat inflammatory and/or tissue degeneration conditions. |
