Abstract

Methods and compositions for treating various indications by lessening oxidative stress in a patient are provided. A pharmaceutical composition comprises between about 0.001% to about 10.0%), or more specifically between about 0.015% to about 5%, sodium iodine or catalase by weight. The iodine ion or the catalase dissociates hydrogen peroxide into water and molecular oxygen to interrupt biological events that result in negative side effects. The pharmaceutical composition further comprises in some cases a reducing agent or various carrier materials. The pharmaceutical composition is in some cases formulated for a variety of delivery methods.

Claims

1. A stable pharmaceutical composition for use in corneal collagen cross-linking, comprising (a) between about 0.015% to about 5% sodium iodide by weight, (b) riboflavin, and (c) a pharmaceutically-acceptable excipient appropriate for ocular administration, wherein the pharmaceutical composition maintains a basic pH that permits iodide ion to catalytically break hydrogen peroxide into water and oxygen.

2. The pharmaceutical composition of claim 1, wherein the pharmaceutical composition comprises about 0.015% sodium iodide by weight.

3. The pharmaceutical composition of claim 1, wherein the basic pH is between 7 and 8.4.

4. The pharmaceutical composition of claim 3, further comprising a reducing agent.

5. The pharmaceutical composition of claim 4, wherein the reducing agent is thiosulfate, vitamin C, or sodium bisulfate.

6. The pharmaceutical composition of claim 1, wherein the pharmaceutically-acceptable excipient is an artificial tear solution.

7. The pharmaceutical composition of claim 1, wherein the pharmaceutical composition is a solution adapted for introduction into the eye and diffusion into the cornea for promoting photochemical corneal cross-linking and reducing oxidative stress.

9. The pharmaceutical composition of claim 1, further comprising 0.5% riboflavin by weight.

10. The pharmaceutical composition of claim 2, further comprising 0.5% riboflavin by weight.

8. A stable pharmaceutical composition, comprising 0.015% sodium iodide by weight and 0.5% riboflavin by weight, and wherein the pharmaceutical composition maintains a basic pH that permits iodide ions to catalytically break hydrogen peroxide into water and oxygen.
