Patent Claims: |
1. A stable topical cream composition comprising: a) 0.2-5% of ozenoxacin, and b) a suitable carrier comprising: b.1) 15-25% of one or more emulsifiers selected from
the group consisting of ethylene glycol monostearate, sorbitan tristearate, a mixture of PEG6 stearate, glycol stearate and PEG32 stearate, and hydrogenated lecithin, and mixtures thereof; b.2) 10-20% of one or more surfactants selected from the group
consisting of sorbitan oleate monoolein/propylene glycol, C.sub.8C.sub.10 fatty acid mono- and diglycerides from coconut oil, soy lecithin, egg phosphatides, citric acid esters of monoglycerides, lactic acid esters of monoglycerides, diacetyl tartaric
acid esters of monoglycerides, succinic acid esters of monoglycerides, sucrose fatty acid esters, polyglycolyzed glycerides of oleic acids, polyglycolyzed glycerides of linoleic acid, polyglycerol esters of fatty acids, and polyglyceryl esters of mixed
fatty acids, and mixtures thereof; b.3) 5-15% of an oil component which is the Guerbet alcohol 2-octyl dodecanol; b.4) 1-10% of one or more low melting point waxes selected from the group consisting of fatty alcohols having 8 to 30 carbon atoms and
mixtures thereof; b.5) water; b.6) 10-20% of one or more water dispersible components selected from the group consisting of polyethylene glycol 400, hexylene glycol, propylene glycol, polypropylene glycol-10 methylglucose ether, ethoxydiglycol,
polyethylene glycol-6 caprylic/capric glyceride, ethylene glycol monobutyl ether, polyethylene glycol-8 caprylic/capric glycerides, 3-methoxy-3-methyl-1-butanol, dimethyl isosorbide, and mixtures thereof; and b.7) 0.01-1% of one or more
non-formaldehyde-donating preservatives; wherein the amount of component b.5 is an amount to complete 100 percent by weight and all percentages being weight percent and based on the total weight of the composition.
2. The stable topical cream composition according to claim 1, wherein the emulsifier is a mixture of PEG6 stearate, glycol stearate and PEG32 stearate. 3. The stable topical cream composition according to claim 1 or 2, wherein the surfactants are polyglycolyzed glycerides of oleic acids. 4. The stable topical cream composition according to claim 1, wherein said low melting point wax is stearyl alcohol. 5. The stable topical cream composition according to claim 1, wherein the water dispersible component is propylene glycol. 6. The stable topical cream composition according to claim 1, wherein the non-formaldehyde-donating preservative is benzoic acid. 7. The stable topical cream composition according to claim 1, wherein the carrier comprises: 18 to 22% of component b.1; 13 to 15% of component b.2; 7 to 9% of component b.3; 3 to 5% of component b.4; component b.5; 13 to 17% of component b.6; 0.05 to 0.15% of component b.7; wherein the amount of component b.5 is an amount to complete 100 percent by weight. 8. The stable topical cream composition according to claim 7, wherein the carrier comprises: 20% of component b.1; 14% of component b.2; 8% of component b.3; 4% of component b.4; component b.5; 15% of component b.6; 0.1% of component b.7; wherein the amount of component b.5 is an amount to complete 100 percent by weight. 9. The stable topical cream composition according to claim 1 in the treatment of skin and skin structure infections in a human or an animal. 10. The stable topical cream composition according to claim 1 in the treatment of sexually transmitted diseases and genital tract infections in a human or an animal. 11. The stable topical cream composition according to claim 1 for use in the eradication of nasopharynx infections in asymptomatic nasal carriers in a human or an animal. 12. A method for treating bacterial infection caused by S. aureus comprising administering the stable topical cream composition of claim 1 to a subject in need thereof. 13. A method for treating bacterial infection caused by Staphylococcus aureus and/or Streptococcus pyogenes comprising administering the stable topical cream composition of claim 1 to a subject in need thereof. |
