Compositions and uses of alpha-adrenergic agents
The disclosure provides cosmetic and therapeutic compositions of alpha-adrenergic agents. Compositions of the disclosure may be used for topical, transdermal or parenteral administration to the eye or eyelid. The compositions of the disclosure may be used cosmetically to improve the appearance of the eye or therapeutically to treat ptosis.
1. A cosmetic gel composition for the eyelid comprising an alpha-adrenergic agent and a permeation enhancer,
wherein a dose of the cosmetic gel composition comprises from about 0.5 mg to 8 mg of the alpha-adrenergic agent
wherein the alpha-adrenergic agent is oxymetazoline or a salt thereof,
wherein the permeation enhancer is less than 40% by weight of the total composition, and
wherein the cosmetic gel composition comprises one or more cosmetic excipients.
2. The cosmetic gel composition of claim 1 , wherein the dose of the cosmetic gel composition comprises from about 3 to 6 mg of oxymetazoline or a salt thereof.
3. The cosmetic gel composition of claim 1 , wherein the permeation enhancer is less than 30% by weight of the total composition.
4. The cosmetic gel composition of claim 1 , wherein the permeation enhancer is less than 20% by weight of the total composition.
5. The cosmetic gel composition of claim 1 , wherein the permeation enhancer is selected from ethanol, propylene glycol, dodecyl-N,N-dimethyl-aminoacetate, ethylacetate, azone, sodium dodecyl sulfate, d-limonene, oleic acid, 1,3-diphenyl-urea, N-methyl-2-pyrrolidone, beta-cyclodextrin, and dimethylsulfoxide.
6. The cosmetic gel composition of claim 1 , wherein said permeation enhancer comprises an alcohol.
7. The cosmetic gel composition of claim 6 , wherein said permeation enhancer comprises propylene glycol.
8. The cosmetic gel composition of claim 1 , wherein said cosmetic gel composition is a controlled-release composition.
9. The cosmetic gel composition of claim 5 , wherein the permeation enhancer increases skin permeation of the alpha-adrenergic agent or the salt thereof by about 0.5 mm or more relative to a composition without the permeation enhancer.
10. The cosmetic gel composition of claim 5 , wherein the permeation enhancer increases skin permeation of the alpha-adrenergic agent or the salt thereof by about 2-fold or greater relative to a composition without the permeation enhancer.
11. The cosmetic gel composition of claim 10 , wherein the permeation enhancer increases skin permeation of oxymetazoline or a salt thereof by about 3-fold or greater relative to a composition without the permeation enhancer.
12. The cosmetic gel composition of claim 1 , further comprising one or more dermatologically acceptable carriers.
13. The cosmetic gel composition of claim 1 , wherein the one or more dermatologically acceptable carriers are individually selected from buffers, preservatives, gelling agents, rheological modifiers and stabilizers, moisturizers, and humectants.
14. The cosmetic gel composition of claim 1 , wherein the one or more cosmetic excipients are individually selected from sunscreens, fragrances, pigments and antioxidants.
15. A method of contacting Muller's muscle with an alpha-adrenergic agent, comprising applying a dose of the cosmetic gel of claim 1 to the exterior surface of the upper eyelid of a subject.
16. A method of permeating the septal fat pad with an alpha-adrenergic agent, comprising applying a dose of the cosmetic gel of claim 1 to the exterior surface of the upper eyelid of a subject.
