Abstract

A method of treating hearing loss includes the step administering a composition to the mammal, wherein the composition consists essentially of a biologically effective amount of vitamin A, vitamin E, vitamin C, a vasodilator comprising magnesium, and, optionally, a withanolide, and/or resveratrol.

First claim

What is claimed is:

1. A method of treating hearing loss, said method comprising the step of internally administering a composition to the mammal, wherein the composition consists essentially of a biologically effective amount of vitamin A, vitamin E, vitamin C, a vasodilator comprising magnesium, and, optionally, a withanolide, and/or resveratrol.

2. A method as set forth in claim 1 wherein the step of internally administering the composition is further defined as orally administering the composition to the mammal.

3. A method as set forth in claim 1 wherein the step of internally administering the composition is further defined as intravenously administering the composition to the mammal.

4. A method as set forth in claim 1 further comprising the step of detecting hearing loss in a mammal.

5. A method as set forth in claim 1 wherein the step of internally administering the composition occurs prior to the step of detecting the hearing loss in the mammal.

6. A method as set forth in claim 5 wherein an average difference in threshold shift in mammals from baseline threshold sensitivity at 4, 8, and 16 kHz, as compared to an untreated control, is at least 25 decibels when the trauma results from exposure to 120 decibel SPL Octave Band Noise centered at 4 kHz for five hours.

7. A method as set forth in claim 1 wherein the composition further comprises resveratrol.

8. A method as set forth in claim 1 wherein the vitamin A is present in the composition in an amount of at least 830 IU.

9. A method as set forth in claim 1 wherein the vitamin C is present in the composition in an amount of at least 4,000 IU.

10. A method as set forth in claim 1 wherein the vitamin E is further defined as a water-soluble analogue of alpha-tocopheral.

11. A method as set forth in claim 1 wherein the vitamin E is present in the composition in an amount of at least 75 IU.

12. A method as set forth in claim 1 wherein the composition further comprises the withanolide.

13. A method as set forth in claim 1 wherein the vasodilator is present in an amount of at least 50 mg.

14. A method as set forth in claim 1 wherein the composition provides an additive effect that is equal to or greater than a sum of the effects of the individual components.

15. A method of treating hearing loss, said method comprising the step of internally administering a composition to the mammal, wherein the composition consists essentially of a biologically effective amount of vitamin A, vitamin E, vitamin C, a vasodilator comprising magnesium, and, optionally, a withanolide, and/or resveratrol, and wherein the composition is administered after peroxyl radical formation.

16. A method as set forth in claim 15 wherein the formation of peroxyl radicals is further defined as oxidative DNA damage.

17. A method as set forth in claim 15 wherein the formation of peroxyl radicals is further defined as oxidative protein damage.

18. A method as set forth in claim 15 wherein the composition provides an additive effect that is equal to or greater than a sum of the effects of the individual components.

19. A method of treating hearing loss, said method comprising the step of internally administering a composition to the mammal, wherein the composition consists essentially of a biologically effective amount of vitamin A, vitamin E, vitamin C, a vasodilator comprising magnesium, and, optionally, a withanolide, and/or resveratrol, and wherein the composition is administered after lipid peroxidation in the mammal.

20. A method as set forth in claim 19 wherein the composition provides an additive effect that is equal to or greater than a sum of the effects of the individual components.

21. A method of treating hearing loss, said method comprising the step of internally administering a composition to the mammal, wherein the composition consists essentially of a biologically effective amount of vitamin A, vitamin E, vitamin C, a vasodilator comprising magnesium, and, optionally, a withanolide, and/or resveratrol, and wherein the composition is administered after vasoconstriction of blood vessels in an ear of the mammal.

22. A method as set forth in claim 21 wherein the composition provides an additive effect that is equal to or greater than a sum of the effects of the individual components.

23. A method of treating hearing loss, said method comprising the step of internally administering a composition to the mammal, wherein the composition consists essentially of a biologically effective amount of vitamin A, vitamin E, vitamin C, a vasodilator comprising magnesium, and, optionally, a withanolide, and/or resveratrol, and wherein the composition is administered after formation of lipid peroxyl radicals within a lipophilic compartment of a mitochondrial membrane in the mammal.

24. A method as set forth in claim 23 wherein the composition provides an additive effect that is equal to or greater than a sum of the effects of the individual components.
