Abstract
A composition for treating hearing loss includes components that function through different biological mechanisms to provide an additive effect that is equal to or greater than a sum of the effect of the individual components. The composition includes a biologically effective amount of at least one scavenger of singlet oxygen, a donor antioxidant, a third antioxidant, and a vasodilator. A method of treating hearing loss includes the step of internally administering the composition including a biologically effective amount of the at least one scavenger of singlet oxygen, the donor antioxidant, the third antioxidant, and the vasodilator to a mammal within three days of trauma to a middle or inner ear of the mammal.
