Abstract

Compositions and methods for treating Trichomoniasis using topically administered antibiotics such as aminoglycosides, including streptomycin, spectinomycin, kanamycin A, amikacin, tobramycin, dibekacin, gentamicin, sisomicin, netilmicin, neomycin B, neomycin C, neomycin E (paromomycin), and the like and combinations thereof.

Claims (21)

1. A method for treating Trichomonas , comprising administering to a subject in need of treatment a composition comprising a ribosomal RNA binding compound having a concentration of about 7.2% (w/w) to about 20% (w/w) and a debriding agent having a concentration of about 0.25% (w/w) to about 20% (w/w) topical debriding agent based on the total composition.

2. The method of claim 1 , wherein the ribosomal RNA binding compound is selected from the group consisting of streptomycin, spectinomycin, kanamycin A, amikacin, tobramycin, dibekacin, gentamicin, sisomicin, netilmicin, neomycin B, neomycin C, neomycin E, paromomycin, and combinations thereof.

3. The method of claim 1 , wherein the antibiotic is paromomycin.

4. The method of claim 1 , wherein the debriding agent is selected from the group consisting of papain, urea, balsam peru, castor oil, trypsin, chlorophyllin copper complex, collagenase, and combinations thereof.

5. The method of claim 1 , where the composition further comprises a base.

6. The method of claim 5 , wherein the base is selected from the group consisting of hydrophilic petrolatum, preserved water, sorbitan monooleate, benzalkonium chloride, mineral oil, plasticized base, glycerin, preserved water, and combinations, analogs, and pharmaceutically acceptable salts thereof.

7. The method of claim 5 , wherein the base has a concentration of about 65% (w/w) to about 90% (w/w) of the total composition.

8. The method of claim 1 , wherein the composition further comprises an emulsifier or surfactant.

9. The method of claim 8 , wherein the emulsifier or surfactant has a concentration of about 0.25% (w/w) to about 5% (w/w) of the total composition.

10. The method of claim 1 , wherein the composition further comprises a humectant.

11. The method of claim 10 , wherein the humectant is selected from the group consisting of calamine, dodecylsulphate, sodium lauryl sulphate (SLS), a polyoxyethylene ester of polysorbitan, sodium dioctylsulphosuccinate (DOSS), lecithin, sodium docusate, and combinations thereof.

12. The method of claim 10 , wherein the humectant is a polyoxyethylene ester of a compound is selected from monooleate, monopalmitate, monostearate, sorbitan, and polyoxyethylene ether.

13. The method of claim 10 , wherein the humectant has a concentration of about 0.01% (w/w) to 5% (w/w) of the total composition.

14. The method of claim 1 , wherein administering is selected from the group consisting of intravaginal, anal, extravaginal administration, and combinations thereof.

15. The method of claim 1 , wherein the composition is formulated in a form selected from the group consisting of creams, ointments, lotions, shampoos, liniments, foams, and soaps.

16. The method of claim 1 , wherein the administering is achieved using a suppository.

17. A composition comprising:

A ribosomal RNA binding compound having a concentration of about 7.2% (w/w) to about 20% (w/w) based on the total composition; and

A debriding agent having a concentration of about 0.25% (w/w) to about 20% (w/w) topical debriding agent based on the total composition.

18. The composition of claim 17 , wherein the ribosomal RNA binding compound is selected from the group consisting of streptomycin, spectinomycin, kanamycin A, amikacin, tobramycin, dibekacin, gentamicin, sisomicin, netilmicin, neomycin B, neomycin C, neomycin E, paromomycin, and combinations thereof.

19. The composition of claim 17 , wherein the debriding agent is selected from the group consisting of papain, urea, balsam peru, castor oil, trypsin, chlorophyllin copper complex, collagenase, and combinations thereof.
