Abstract

Provided herein are compositions and formulations comprising an antifungal agent. Pharmaceutical compositions comprising luliconazole in an amount effective for the treatment of onychomycosis are provided. Also provided are methods for treating dermatomycoses and onychomycosis using the compositions and formulations.

Claims (41)

1. A method of treating onychomycosis in an individual in need thereof, comprising contacting the individual's nail with a pharmaceutical composition comprising:

from about 9 weight percent to about 12.5 weight percent luliconazole;

from about 8 weight percent to about 15 weight percent acetone;

from about 3 weight percent to about 8 weight percent propylene carbonate;

from about 20 weight percent to about 30 weight percent of an ethylene glycol derivative of the formula HOCH 7 CH 2 OCH 7 CH 2 OR where R is an alkyl group having 1 to 6 carbon atoms;

from 0.01 weight percent to about 6 weight percent benzyl alcohol;

from 0.01 weight percent to about 4 weight percent of a film forming agent; and

from about 20 weight percent to about 60 weight percent of ethanol.

2. The method of claim 1 , wherein R is ethyl.

3. The method of claim 1 , wherein the composition comprises 2 weight percent to 4 weight percent benzyl alcohol.

4. The method of claim 1 , wherein the film-forming agent is a maleic anhydride/methyl vinyl ether copolymer.

5. The method of claim 1 , wherein the film forming agent is a butyl ester of polyvinylmethylether maleic anhydride copolymer.

6. The method of claim 1 , wherein the composition comprises from about 35 weight percent to about 45 weight percent ethanol.

7. The method of claim 3 , wherein R is ethyl.

8. The method of claim 4 , wherein the composition comprises about 2 weight percent to about 4 weight percent benzyl alcohol.

9. The method of claim 2 , wherein the film-forming agent is a maleic anhydride/methyl vinyl ether copolymer.

10. The method of claim 2 , wherein the film forming agent is a butyl ester of polyvinylmethylether maleic anhydride copolymer.

11. The method of claim 8 , wherein the composition comprises from about 35 weight percent to about 45 weight percent ethanol.

12. The method of claim 1 , wherein the composition comprises about 10 weight percent luliconazole.

13. The method of claim 1 , wherein the method is a method of treating distal subungual onychomycosis.

14. The method of claim 1 , wherein the onychomycosis is an infection of a toenail.

15. The method of claim 1 , wherein the onychomycosis is an infection of a fingernail.

16. The method of claim 1 , wherein the method comprises contacting the individual's nail with the composition once daily.

17. The method of claim 1 , wherein the individual is diabetic, is of an advanced age or is immunocompromised.

18. The method of claim 1 , wherein the composition comprises:

from 9 weight percent to 12.5 weight percent luliconazole;

from 8 weight percent to 15 weight percent acetone;

from 3 weight percent to 8 weight percent propylene carbonate;

from 20 weight percent to 30 weight percent of an ethylene glycol derivative of the formula HOCH 2 CH 2 OCH 2 CH 2 OR where R is an alkyl group having 1 to 6 carbon atoms;

from 0.01 weight percent to 6 weight percent benzyl alcohol;

from 0.01 weight percent to 4 weight percent of a film forming agent; and

from 20 weight percent to 60 weight percent of ethanol.

19. The method of claim 18 , wherein the composition comprises:

10 weight percent luliconazole;

12 weight percent acetone;

5 weight percent propylene carbonate;

25 weight percent of an ethylene glycol derivative of the formula HOCH 2 CH 2 OCH 2 CH 2 OR where R is ethyl; and

4 weight percent benzyl alcohol.

20. The method of claim 19 , wherein the composition further comprises a film forming agent in 1 weight percent.

21. The method of claim 20 , wherein the film-forming agent is a maleic anhydride/methyl vinyl ether copolymer.

22. The method of claim 20 , wherein the film forming agent is a butyl ester of polyvinylmethylether maleic anhydride copolymer.
