Abstract

The present invention relates to topical antibacterial compositions. The compositions comprise an antibacterial agent such as mupirocin, water, a polymer and a volatile solvent present in an amount of less than about 40%. The invention also relates to methods of treatment by administering the compositions to a patient in need thereof, and to the use of such compositions in the treatment of bacterial conditions.

Claims

1. A topical pharmaceutical composition comprising a therapeutically effective amount of an antibacterial agent, a polymer, water, less than about 40% w/w of at least one volatile solvent, and optionally one or more dermatologically acceptable excipients.

2. The composition according to claim 1 wherein the antibacterial agent is mupirocin, gentamicin, neomycin, streptomycin, cefpodoxime proxetil, clindamycin, lincomycin, erythromycin, bacitracin, gramicidin(s), vancomycin, doxycycline, minocycline, oxytetracycline, tetracycline, fosfomycin, fusidic acid, sulfacetamide, metronidazole, benzoyl peroxide and dapsone, pharmaceutically acceptable salts thereof, and mixtures thereof.

3. The composition according to claim 2 wherein the antibacterial agent is present in an amount from about 0.1% to about 10% by weight.

4. The composition according to claim 1 wherein the at least one volatile solvent is selected from ethanol, propanol, iso-propanol, n-butyl alcohol, t-butyl alcohol, butoxy ethanol, acetone, ethyl acetate or butyl acetate.

5. The composition according to claim 4 wherein the at least one volatile solvent present in the composition is ethanol.

6. The composition according to claim 5 wherein the volatile solvent is a mixture of at least two volatile solvents, and wherein the first volatile solvent is ethanol.

7. The composition according to claim 6 wherein the volatile solvent is a mixture of ethanol and iso-propanol.

8. The composition according to claim 6 wherein the volatile solvent is a mixture of ethanol and ethyl acetate.

9. The composition according to claim 1 wherein the topical pharmaceutical composition further comprises a second pharmaceutically acceptable active agent.

10. The composition according to claim 9 wherein the second pharmaceutically acceptable active agent is selected from the group consisting of a second antibacterial agent, a retinoid, a corticosteroid, an antifungal agent, a skin conditioning agent, a nutritional agent, or an antiseptic agent.

11. The composition according to claim 1 wherein the one or more dermatologically acceptable excipients are selected from the group consisting of at least one co-solvent, a pH adjusting agent, a humectant, a film extender, a chelating agent, an antioxidant, a preservative, a gelling agent, a fragrance, a colorant, a penetration enhancer, and a combination or mixture thereof.

12. The composition according to claim 11 wherein the at least one co-solvent is selected from an alcohol, a carboxylic acid, a diol, a polyol or a combination or mixture thereof, present in an amount from about 1% to about 30% by weight.

13. The composition according to claim 12 wherein the alcohol is selected from amyl alcohol, benzyl alcohol, cyclohexanedimethanol, diacetone alcohol, hexyl alcohol, or tetrahydrofurfuryl alcohol;

and the diol is selected from 1,2-hexanediol, butylene glycol, diethylene glycol, dipropylene glycol, ethyl hexanediol, ethylene glycol, hexylene glycol, pentylene glycol, propylene glycol, tetraethylene glycol, triethylene glycol, or tripropylene glycol; and

the polyol is selected from polyethylene glycol, butanetriol, glycerol and 1,2,6-hexanetriol.

14. The composition according to claim 11 wherein the at least one co-solvent is propylene glycol, the co-solvent is a mixture of at least two co-solvents which are polyethylene glycol and propylene glycol.

15. The composition according to claim 1 which comprises a volatile solvent present in an amount from about 10% to about 25% by weight and which composition is substantially devoid or devoid of a co-solvent.

19. A method of treating a bacterial infection of the skin in a mammal in need thereof, comprising administering to said mammal, a topical pharmaceutical composition according to claim 1.

20. The method according to claim 19 wherein the bacterial infection of the skin is acne, impetigo, superficially infected dermatoses, wounds which have become infected, rosacea or folliculitis.

16. A topical pharmaceutical composition comprising:

(a) calcium mupirocin,

(b) a PVP/VA co-polymer in an amount from about 30% to about 60% by weight,

(c) water in an amount from about 20% to about 40% by weight, and

(d) a volatile solvent in an amount from about 10% to about 25% by weight; and

optionally a gelling agent, and other dermatologically acceptable excipients thereof.

70 to about 70;

30.

18. The composition according to claim 17 wherein the PVP/VA is present in a ratio of about 30:

70 and wherein the composition is free of hexylene glycol.

21. A method of treating a bacterial infection of the skin in a mammal in need thereof, comprising administering to said mammal, a topical pharmaceutical composition according to claim 16.

22. The method according to claim 21 wherein the bacterial infection of the skin is acne, impetigo, superficially infected dermatoses, wounds which have become infected, rosacea or folliculitis.
