Nicotinamide riboside compositions for topical use in treating skin conditions
Compositions containing nicotinamide riboside (NR) are provided. NR containing compositions are used in the care or treatment of skin and skin conditions. In some embodiments, the invention relates to pharmaceutical compositions and cosmetic compositions containing nicotinamide riboside. In further embodiments, the invention relates to methods of using nicotinamide riboside to promote the increase of intracellular levels of nicotinamide adenine dinucleotide (NAD+) in cells and tissues for improving cell and tissue survival. A method of treating signs or symptoms of aging or skin wrinkles in an individual is provided, comprising topically administering to the individual in need of such treatment an effective amount of the compound nicotinamide riboside, or salts thereof.
1. A chemoprotective method for treating UV-mediated DNA damage in the skin of an individual comprising topically administering to the individual in need of such treatment a therapeutically effective amount of the compound nicotinamide riboside, or a salt thereof.
2. The chemoprotective method of claim 1 , wherein the individual is a human.
3. The chemoprotective method of claim 2 , wherein the nicotinamide riboside compound, or a salt thereof, is provided in a composition comprising a pharmaceutically acceptable carrier.
4. The chemoprotective method of claim 3 , wherein the nicotinamide riboside compound is a salt selected from the group consisting of fluoride, chloride, bromide, iodide, formate, acetate, ascorbate, benzoate, carbonate, citrate, carbamate, gluconate, lactate, methyl bromide, methyl sulfate, nitrate, phosphate, diphosphate, succinate, sulfate, and trifluoroacetate.
5. The chemoprotective method of claim 4 , wherein the nicotinamide riboside compound is a chloride salt.
6. The chemoprotective method of claim 3 , wherein the therapeutically effective amount of nicotinamide riboside compound, or a salt thereof, for a total dose is in a range of about 0.01% by weight to about 50% by weight based on the total weight of the composition.
7. The chemoprotective method of claim 3 , wherein the therapeutically effective amount of nicotinamide riboside compound, or a salt thereof, for a total dose is in a range of about 0.1% by weight to about 10% by weight based on the total weight of the composition.
8. The chemoprotective method of claim 1 , wherein DNA damage indicated by formation of cyclobutane-pyrimidine dimers (CPDs) or 6-4 photoproducts (64 pps) is decreased by greater than about 10%.
9. A cytoprotective method for treating oxidative damage in the skin of an individual comprising topically administering to the individual in need of such treatment a therapeutically effective amount of the compound nicotinamide riboside, or a salt thereof.
10. The cytoprotective method of claim 9 , wherein the individual is a human.
11. The cytoprotective method of claim 10 , wherein the nicotinamide riboside compound, or a salt thereof, is provided in a composition comprising a pharmaceutically acceptable carrier.
12. The cytoprotective method of claim 11 , wherein the nicotinamide riboside compound is a salt selected from the group consisting of fluoride, chloride, bromide, iodide, formate, acetate, ascorbate, benzoate, carbonate, citrate, carbamate, gluconate, lactate, methyl bromide, methyl sulfate, nitrate, phosphate, diphosphate, succinate, sulfate, and trifluoroacetate.
13. The cytoprotective method of claim 12 , wherein the nicotinamide riboside compound is a chloride salt.
14. The cytoprotective method of claim 11 , wherein the therapeutically effective amount of nicotinamide riboside compound, or a salt thereof, for a total dose is in a range of about 0.01% by weight to about 50% by weight based on the total weight of the composition.
15. The cytoprotective method of claim 11 , wherein the therapeutically effective amount of nicotinamide riboside compound, or a salt thereof, for a total dose is in a range of about 0.1% by weight to about 10% by weight based on the total weight of the composition.
16. The cytoprotective method of claim 9 , wherein cell death is decreased by greater than about 10%.
