Compositions and methods of reducing dry mouth
Oral compositions and methods of use thereof are provided herein. The oral compositions comprise a first component comprising at least one E h -raising compound and a pharmaceutically acceptable carrier, and a second component comprising at least one zinc compound, an anti-microbial agent and a pharmaceutically acceptable carrier.
1. A method for reducing or alleviating dry mouth comprising delivering an oral composition to an oral cavity in a subject in need thereof, wherein the oral composition comprises:
a first component comprising at least one E h -raising compound and a pharmaceutically acceptable carrier;
a second component comprising at least one zinc compound and a pharmaceutically acceptable carrier; and
at least one agent to reduce or alleviate dry mouth, wherein the at least one agent to reduce or alleviate dry mouth is present in the first component, or the second component, or both the first and the second component.
2. The method of claim 1 , further comprising mixing the first component and the second component prior to delivering the oral composition to the oral cavity in the subject.
3. The method of claim 1 , wherein the at least one E h -raising compound is selected from the group consisting of hydrogen peroxide, a fermentable sugar, an oxyhalogen compound, a biologically compatible oxidation-reduction buffer, and a combination thereof.
4. The method of claim 1 , wherein the at least one zinc compound is selected from the group consisting of zinc chloride, zinc acetate, zinc salicylate, zinc sulfate, zinc nitrate, and a combination thereof.
5. The method of claim 1 , wherein the at least one agent to reduce or alleviate dry mouth is selected from the group consisting of lactoferrin, lysozyme, lactoperoxidase, immunoglobulins, colustrum extract, glucose oxidase, amylase, amyloglucosidase, glucoxidase, papain, peptizyme, and aloe vera.
6. The method of claim 1 , wherein the at least one E h -raising compound is sodium chlorite, and wherein the at least one zinc compound is selected from the group consisting of zinc chloride and zinc acetate.
7. The method of claim 1 , wherein the first component comprises about 0.01% by weight to about 3.0% by weight of the at least one E h -raising compound, and wherein the second component comprises about 0.02% by weight to about 1.0% by weight of zinc compound.
8. The method of claim 1 , wherein the at least one E h -raising compound is selected from the group consisting of an oxyhalogen compound and hydrogen peroxide, and wherein the first component further comprises a chlorine-containing compound selected from the group consisting of an alkali metal chloride salt, an alkaline earth metal chloride salt, and a combination thereof.
9. The method of claim 8 , wherein the first component comprises about 0.5% by weight to about 2.5% by weight of the chlorine-containing compound, and wherein the second component comprises about 0.02% by weight to about 1.0% by weight of zinc compound.
10. The method of claim 1 , wherein a pH of the first component ranges from about 7.0 to about 8.5, and a pH of the second component ranges from about 3.0 to about 6.0.
11. The method of claim 1 , wherein the first component comprises about 0.04% by weight to about 1.2% by weight of sodium chlorite and a pH of the first component ranges from about 7.0 to about 8.5, and wherein the second component comprises about 0.04% by weight to about 0.7% by weight of zinc compound and a pH of the second component ranges from about 3.0 to about 6.0.
12. The method of claim 1 , wherein the subject is human.
13. The method of claim 1 , wherein the subject is a non-human animal.
14. A method for reducing or alleviating dry mouth comprising delivering an oral composition to an oral cavity in a subject in need thereof, wherein the oral composition comprises:
a first component comprising at least one E h -raising compound and a pharmaceutically acceptable carrier;
a second component comprising at least one zinc compound and a pharmaceutically acceptable carrier; and
at least one humectant, wherein the at least one humectant is present in the first component, or the second component, or both the first and the second component.
15. The method of claim 14 , wherein the humectant is selected from the group consisting of glycerin, propylene glycol, hydrogenated glucose syrup, polyethylene glycol, propylene glycol, glycerol, erythritol, xylitol, sorbitol, mannitol, lactitol, and hydrogenated starch hydrolyzates.
16. The method of claim 15 , wherein the humectant is sorbitol.
17. The method of claim 15 , wherein the at least one E h -raising compound is selected from the group consisting of hydrogen peroxide, sodium chlorite and a fermentable sugar; and the at least one zinc compound is selected from the group consisting of zinc chloride and zinc acetate.
18. The method of claim 14 , further comprising mixing the first component and the second component prior to delivering the oral composition to the oral cavity in the subject.
19. The method of claim 14 , wherein the at least one E h -raising compound is selected from the group consisting of hydrogen peroxide, a fermentable sugar, an oxyhalogen compound, a biologically compatible oxidation-reduction buffer, and a combination thereof.
20. The method of claim 14 , wherein the at least one zinc compound is selected from the group consisting of zinc chloride, zinc acetate, zinc salicylate, zinc sulfate, zinc nitrate, and a combination thereof.
