Definitions
- the present invention relates to topical compositions for the treatment of fungal infections.
- topical compositions described herein are useful for the treatment of onychomycosis.
- onychomycosis has been treated with an oral medicine known as Griseofulvin®, which is largely ineffectual and has undesired side effects.
- Other treatments used to combat onychomycosis include Lamisil® (terbinafine), which is taken once a day for 90 days resulting in nail clearing in 70-80% of patients for one year.
- Lamisil® terbinafine
- Sporanox® itraconazole
- Cost is also a problem, with a typical course of itraconazole treatment in the $600 range.
- Fluconazole may also be used to treat onychomycosis, however, it also has severe side effects. Given the poor cure rate, undesirable side effects and high costs associated with existing treatments, a significant need exists for effect cost effective treatments for onychomycosis.

- the present invention is based, in part, on the findings of in vitro microbiological tests that a topical formulation containing one or more of the following active agents; (-) menthol, or a menthol derivative or analog, e.g., menthone, menthyl salicylate, (-) (1R) menthyl acetate, (-) (1R) menthyl chloride, and menthyloxyacetic acid, and preferably further comprising camphor, is effective in the topical treatment of fungal infections, particularly onychomycosis, as well as dermatophytic fungi.
- the formulation of the invention comprises either a cream-based carrier, petroleum hydrocarbon-based carrier, or, preferably, an alcohol-based gel carrier.
- the preferred alcohol-based gel carrier comprises a C j -C 9 alkyl alcohol, preferably ethanol; a gel forming agent, preferably either hydroxypropyl cellulose or carboxy methyl cellulose; and a preservative, preferably propylene glycol or methyl paraben.
- the present formulation has several advantages over prior art forr are particularly desirable for treating fungal infections of the nail, which include the ability to penetrate the nail, and attack fungus residing in the nail bed.
- the term "dermatophytic fungal infection” refers to an infection of the dermis or nails (fingernails, toenails, or, for non-human animals, hooves or claws) by a fungus.
- fungi include, but are not limited to, Trichophyton rubrum, Trichophyton mentagrophytes, Epidermophytonfloccosum, Aspergillus fumigatus, and Candida albicans.
- an infection can be called “onychomycosis,” which is a general term referring to the infection of the nail by any fungal species.
- the term “affected area” is understood herein to include dermis or nails.
- the term “nails” includes fingernails, toenails, or, for non-human animals, hooves or claws.
- menthol derivative or analog refers to a molecule that shares structural and functional features in common with menthol, and which may be prepared by chemical treatment of menthol.
- a menthol derivative or analog has antifungal activity.
- derivatives and analogs include, but are not limited to menthone, menthyl salicylate, menthyl acetate, menthyl chloride, and menthoxyacetic acid.
- pharmaceutically acceptable refers to molecular entities and compositions that are physiologically tolerable and do not typically produce an allergic or similar untoward reaction, such as gastric upset, dizziness and the like, when administered to a human.
- pharmaceutically acceptable means approved by a regulatory agency of the Federal or a state government, or listed in the U.S. Pharmacopeia or other generally recognized pharmacopeia for use in animals, and more particularly in humans.
- carrier refers to a diluent, adjuvant, excipient, or vehicle with which the compound is administered.
- Such pharmaceutical carriers can be sterile liquids, such as water and oils, including those of petroleum, animal, vegetable or synthetic origin, such as peanut oil, soybean oil, mineral oil, sesame oil and the like.
- Water or aqueous solution saline solutions and aqueous dextrose and glycerol solutions are preferably employed as carriers, particularly for injectable solutions.
- a pharmaceutically acceptable a preferably enhances delivery of the active agent (menthol or menthol derivative or analog) to the nail bed.
- Suitable pharmaceutical carriers are described in "Remington's Pharmaceutical Sciences” by E.W. Martin, 17 th Edition.
- therapeutically effective amount'Or “effective amount” is used herein to mean an amount sufficient to reduce by at least about 15 percent, preferably by at least 50 percent, more preferably by at least 90 percent, and most preferably prevent, a clinically significant deficit in the activity, function and response of the host. Alternatively, a therapeutically effective amount is sufficient to cause an improvement in a clinically significant condition in the host.
- the term "about” or “approximately” means that the referenced value can vary by 20%, preferably by 10%, more preferably by 5%, and more preferably by 1%.
- the term can also mean that the value varies by an acceptable amount, e.g. , the acceptable variance for components of a composition for regulatory approval, or within the limits of accurate measurement.
- compositions The amount of active agent(s) in the formulation of the invention may range from about 2% to about 10% by weight of the total composition, and preferably is about 4%. Additionally, camphor may be added to the formulation in an amount of from about 2% to about 11% by weight of the total composition, preferably about 2% to about 4.6%.
- a suitable pharmaceutically acceptable carrier provides high viscosity and adhesiveness to hold the active agent in place at the nail and to ensure sufficient opportunity for effective penetration.
- suitable carriers include petroleum hydrocarbon bases, creams, and gels, e.g., an alcohol-based gel.
- Petroleum hydrocarbons selected for compositions of the invention are preferably high molecular weight hydrocarbons, with a melting point above body temperature (37°C).
- petroleum or petroleum jelly may be employed as suitable carriers for the active ingredient(s).
- petrolatum has been found to be a particularly suitable vehicle to use.
- Cream formulations are widely used, industry standard, buffered formulations, typically used for agents which are soluble in alcohol and poorly soluble in water.
- Such creams may contain cetyl alcohol, cetyl palmitate, copolyol, EDTA, glycerin, H 2 0, imidazole-urea, isopropyl palmitate, methyl paraben, PEG- 100 stearate, sodium hydroxide, turpentine, stearic acid, or stearyl alcohol.
- Creams which include lotions, salves, and the like, are well known in the art.

- a preferred alcoholic-based gel carrier contains a C C 9 alkyl alcohol, preferably ethanol, present in about 15% to about 50%) of the total composition.
- the carrier also preferably includes a gel forming agent, preferably either hydroxypropyl cellulose or carboxymethylcellulose present in a concentration of about 1 % to 5% by weight of the total composition.
- the alcohol-based gel composition can be brought to 100% by the addition of water and brought to neutral pH (pH 7) by the addition of sodium hydroxide.
- the alcohol used in the composition should be water free.
- the carrier includes a preservative, preferably either propylene glycol or methyl paraben present in a concentration of about 5% to 25% by weight of the total composition.
- a preferred alcoholic composition of the present invention comprises 2% (w/w) carboxymethylcellulose; 30%) (w/w) ethanol; 15% propylene glycol or methyl paraben; 4% (w/w) menthol and 2% (w/w) camphor. Water is then added to bring the total to 100% and the solution neutralized to pH 7 by the addition of sodium hydroxide.
- compositions of the present invention may be packaged in an appropriate container.
- the compositions may be supplied in bottles with brush applicators or applicator tipped bottles or glass rod applicator bottles.
- Treatment of Fungal Infections A typical protocol for using the compositions of the invention on an animal with onychomycosis is as follows.
- compositions of the invention should follow thorough cleansing of the affected area, and be as complete as possible.
- topical administration of the composition of the invention should follow thorough cleansing of the affected area, and be as complete as possible.
- the composition is worked under the nail, e.g., into any spaces that have formed, and around the edge of the nail.
- the antifungal compositions of the invention are applied twice within every 24 hour period.
- the compositions of the invention may be applied for at least about one month for a milder infection, and for about two or more months to clear a more advanced infection, or where the entire nail is involved.
- Therapeutic effectiveness is observed by a reversal of nail deterioration or pain, and by an improvement in nail appearance. These methods can also be used to treat reinfection, should that occur.
- Agents (A) and (B) were dissolved in H 2 O.
- Agents (E), (F) and (H) were dissolved in 90% Ethanol as the vehicle.
- Agents (C) and (D) were heated to approximately 80 °C in a sealed container to render them more liquid and easier to spread on the petri dish.
- An additional petri dish with no agent added served as a control and supported fungal growth identical to that seen in the plates treated with 90% ethanol. Fungal growth is evident as black areas on the petri dish following a period of growth (typically 7-14 days) at
- Menthone > Menthol Menthyloxyacetic acid> Menthyl salicylate> Menthyl acetate> Menthyl chloride.
- Camphor on its own, has little or no detectable anti-fungal activity. However a composition of 4% Menthol with 2% Camphor was significantly more potent in its ability to kill toenail fungus. The camphor also likely acted as a penetration agent allowing better access of the Menthol to the fungus under the toenail bed.
- EXAMPLE 2 Antifungal Compositions This example describes two formulations for delivery of a topical anti- onychomycotic agent.
- the formulations contain Menthol or an Analogue at 4% (W/V), and
- This example describes a simplified gel for topical delivery of Menthol and Camphor, useful as an anti-onychomycotic agent.
- the formulation of the gel is: 2% (w/v) carboxymethylcellulose (gelling agent), 30% (v/v) ethanol (to maintain Menthol and Camphor in solution), 15% (w/v) propylene glycol or methyl paraben (as a preservative), neutralized with sodium hydroxide, and completed to 100% with H 2 0.
- Menthol is added to 4% (w/v), and camphor to 2% (w/v).
- EXAMPLE 4 Antifungal Activity of Compositions This example reports results using menthol at concentrations of 0, 0.1 , 0.3 , 1 ,
- Candida albicans and Epidermophytonfloccosum were each inoculated onto a petri dish, scraped off, vortexed to break up mycelial bodies and diluted before being replated on petri dishes with menthol or menthol/camphor in the concentrations described above. After the appropriate growth period (2-3 weeks for Trichophyton rubrum, Trichophyton mentagrophytes and Epidermophytonfloccosum, 1 week for Aspergillus fumigatus and 5 days for Candida albicans) each dish was scored for colony number compared to the control plates.
- Affected nail including all 'white-tarnished' infected regions is removed, without injuring the cuticle or underlying nail bed.
- a sharp pair of nail-clippers is an ideal tool, preferably not leaving infected sections of nail undisturbed.
- composition of the invention is applied, paying particular attention to spaces where the nail is no longer attached to the nail bed.
- the composition is pushed under and in-between all accessible areas.
- Application is repeated twice daily (once in the morning and once at night) for 6 weeks for less severe infections, or for two months where the infection is long- term and the entire nail is affected. A significant improvement in the treated nail's appearance is evident after 3-4 weeks.
