Topical pterostilbene compositions for use in treating UV-induced loss of barrier function in skin
View Patent ↗A chemoprotective method for treating, inhibiting or preventing loss of barrier function in skin caused by ultraviolet (UV) light by using an effective amount of pterostilbene is provided. Pharmaceutical and nutraceutical compositions containing pterostilbene suitable for administration to an individual in order to prevent subsequent UV-mediated loss of barrier function in skin are provided.
1. A method for treating, inhibiting or preventing loss of barrier function in skin due to a burn injury, as indicated by transepidermal water loss (TEWL), the method comprising administering to an individual in need of such treatment an effective amount of the compound pterostilbene.
2. The method of claim 1 , wherein the individual is a human.
3. The method of claim 2 , wherein the pterostilbene compound is provided in a composition comprising a pharmaceutically or nutraceutically acceptable carrier.
4. The method of claim 3 , wherein the effective amount of pterostilbene 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.
5. The method of claim 4 , wherein the effective amount of pterostilbene for a total daily dose is in a range of about 1 mg to about 1000 mg.
6. The method of claim 1 , wherein the route of administration of the compound is selected from the group consisting of oral, topical, intradermal, transdermal, and subcutaneous.
7. The method of claim 1 , wherein the route of administration is topical.
8. The method of claim 7 , wherein the individual is a human.
9. The method of claim 8 , wherein the pterostilbene compound is provided in a composition comprising a pharmaceutically acceptable carrier.
10. The method of claim 9 , wherein the effective amount of pterostilbene 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.
11. The method of claim 10 , wherein the effective amount of pterostilbene for a total daily dose is in a range of about 1 mg to about 1000 mg.
12. The method of claim 1 , wherein the method comprises measuring TEWL in the individual before and after administration of pterostilbene.
13. The method of claim 12 , wherein the loss of barrier function indicated by TEWL is decreased, relative to the loss of barrier function expected for untreated skin.
