Treatment of allergic eye conditions with cyclodextrins
The present disclosure provides methods of treating eye allergies and allergic conjunctivitis with cyclodextrin. Ophthalmic compositions of cyclodextrin for topical administration are also provided.
1. A method of treating eye allergy, comprising topically administering to an eye of a subject in need thereof a therapeutically effective amount of an ophthalmic composition comprising a cyclodextrin, wherein the composition has cyclodextrin as the sole pharmaceutically active agent.
2. The method of claim 1 , wherein the eye allergy is manifested as allergic conjunctivitis.
3. The method of claim 1 , wherein the allergic conjunctivitis is seasonal allergic conjunctivitis, perennial allergic conjunctivitis, vernal conjunctivitis, or atopic keratoconjunctivitis.
4. The method of claim 1 , wherein the cyclodextrin is selected from α-cyclodextrin, β-cyclodextrin, γ-cyclodextrin, derivatives thereof, and combinations thereof.
5. The method of claim 1 , wherein the cyclodextrin comprises β-cyclodextrin or a derivative thereof.
6. The method of claim 5 , wherein the β-cyclodextrin or a derivative thereof is carboxyalkyl-β-cyclodextrin, hydroxyalkyl-β-cyclodextrin, sulfoalkylether-β-cyclodextrin, alkyl-β-cyclodextrin, or combinations thereof.
7. The method of claim 5 , wherein the β-cyclodextrin is sulfoalkylether-β-cyclodextrin or hydroxyalkyl-β-cyclodextrin.
8. The method of claim 7 , wherein the sulfoalkylether-β-cyclodextrin is sulfobutylether-β-cyclodextrin.
9. The method of claim 7 , wherein the hydroxyalkyl-β-cyclodextrin is hydroxypropyl-β-cyclodextrin.
10. The method of claim 1 , wherein the cyclodextrin is present at about 0.1 to about 30% w/v.
11. The method of claim 1 , wherein the cyclodextrin is present at about 0.1 to about 25% w/v.
12. The method of claim 1 , wherein the cyclodextrin is present at about 0.1 to about 20% w/v.
13. The method of claim 1 , wherein the cyclodextrin is present at about 0.5% to about 10% w/v.
14. The method of claim 1 , wherein the composition further comprises one or more of an ophthalmic pharmaceutically acceptable excipient.
15. The method of claim 14 , wherein the ophthalmic pharmaceutically acceptable excipient is selected from a tonicity agent, preservative, buffering agent, wetting agent, viscosity enhancing agent, lubricating agent, chelating agent, and antioxidant.
16. A method of preventing or ameliorating onset of symptoms of eye allergy, comprising topically administering to an eye of a subject in need thereof an effective amount of an ophthalmic composition comprising a cyclodextrin, wherein the composition has cyclodextrin as the sole pharmaceutically active agent and wherein the subject has been previously diagnosed with an eye allergy.
17. The method of claim 16 , wherein the cyclodextrin is selected from α-cyclodextrin, β-cyclodextrin, γ-cyclodextrin, derivatives thereof, and combinations thereof.
18. The method of claim 17 , wherein the cyclodextrin comprises β-cyclodextrin or a derivative thereof.
19. The method of claim 18 , wherein the β-cyclodextrin or a derivative thereof is carboxyalkyl-β-cyclodextrin, hydroxyalkyl-β-cyclodextrin, sulfoalkylether-β-cyclodextrin, alkyl-β-cyclodextrin, or combinations thereof.
20. The method of claim 19 , wherein the β-cyclodextrin is sulfoalkylether-β-cyclodextrin or hydroxyalkyl-β-cyclodextrin.
21. The method of claim 20 , wherein the sulfoalkylether-β-cyclodextrin is sulfobutylether-β-cyclodextrin.
22. The method of claim 20 , wherein the hydroxyalkyl-β-cyclodextrin is hydroxypropyl-β-cyclodextrin.
23. The method of claim 16 , wherein the cyclodextrin is present at about 0.1 to about 30% w/v.
24. The method of claim 16 , wherein the composition further comprises one or more of an ophthalmic pharmaceutically acceptable excipient.
25. The method of claim 24 , wherein the ophthalmic pharmaceutically acceptable excipient is selected from a tonicity agent, preservative, buffering agent, wetting agent, viscosity enhancing agent, lubricating agent, chelating agent, and antioxidant.
26. The method of claim 16 , wherein the cyclodextrin is present at about 0.1 to about 20% w/v.
27. The method of claim 16 , wherein the cyclodextrin is present at about 0.5% to about 10% w/v.
28. The method of claim 1 , wherein the composition is administered as needed.
29. The method of claim 1 , wherein the composition is administered at least once per day.
30. The method of claim 1 , wherein the composition is administered at least two times per day, at least three times per day, at least four times per day, at least five times per day, or at least six times per day.
