6. The gel composition of claim 5 , wherein the alkyl alcohol is ethanol.
7. The gel composition of claim 1 , wherein the hydroxy cellulose is hydroxyethyl cellulose.
8. The gel composition of claim 1 , wherein the polysorbate solubilizing agent is Polysorbate 20.
9. The gel composition of claim 1 , wherein the polysorbate solubilizing agent is Polysorbate 80.
10. The gel composition of claim 1 , wherein the naftifine, or pharmaceutically acceptable salt thereof, is naftifine hydrochloride.
11. The gel composition of claim 1 , wherein the naftifine, or a pharmaceutically acceptable salt thereof, is present in an amount of about 2.0 wt %, the glycol solvent is present in an amount of about 20 wt %, the alkyl alcohol solvent is present in an amount of about 19 wt %, the non-carbomer rheology modifier is present in an amount of about 1.75 wt %, and the polysorbate solubilizing agent is present in an amount of about 5 wt %.
12. The gel composition of claim 11 , wherein the glycol solvent is propylene glycol.
13. The gel composition of claim 11 , wherein the alcohol solvent is ethanol.
14. The gel composition of claim 11 , wherein the non-carbomer rheology modifier is hydroxyethyl cellulose.
15. The gel composition of claim 11 , wherein the polysorbate solubilizing agent is Polysorbate 20 or Polysorbate 80.
16. The gel composition of claim 11 , wherein the naftifine or pharmaceutically acceptable salt thereof is naftifine hydrochloride.
17. The gel composition of claim 1 , wherein the pH adjuster is present in an amount of from about 0.14 wt % to about 0.21 wt %.
18. The gel composition of claim 17 , wherein the pH adjuster is present in an amount of from about 0.15 wt % to about 0.2 wt %.
19. The gel composition of claim 18 , wherein the pH adjuster is present in an amount of from about 0.16 wt % to about 0.19 wt %.
20. A gel composition for topical administration comprising:
(i) naftifine or a pharmaceutically acceptable salt thereof, present in an amount of from about 0.5 wt % to about 4 wt %;
(ii) a solvent comprising an alkyl alcohol solvent component, present in an amount of from about 10 wt % to about 50 wt %;
(iii) a non-carbomer rheology modifier selected from a hydroxy cellulose, present in an amount of from about 0.75 wt % to about 2.25 wt %;
(iv) a polysorbate solubilizing agent present in an amount of from about 3 wt % to about 8 wt %;
(v) an amine pH adjuster; and
one or more of: water, a preservative, a chelating agent, a coloring agent, and a fragrance.
21. The gel composition according to claim 20 , wherein the non-carbomer rheology modifier is hydroxypropyl cellulose.
22. The gel composition according to claim 20 , wherein the alkyl alcohol solvent is present in an amount of from about 20 wt % to about 45 wt %.
