Description
BACKGROUND OF THE INVENTION
[0002] 1. Field of Invention
[0003] The present invention relates to treatment and prevention of tinea cruris, commonly known as Jock Itch.
[0004] 2. Description of Related Art
[0005] Monomer and polymer adhesives are used in both industrial (including household) and medical applications. Included among these adhesives are the 1,1-disubstituted ethylene monomers and polymers, such as the α-cyanoacrylates. Since the discovery of the adhesive properties of such monomers and polymers, they have found wide use due to the speed with which they cure, the strength of the resulting bond formed, and their relative ease of use. These characteristics have made the α-cyanoacrylate adhesives the primary choice for numerous applications such as bonding plastics, rubbers, glass, metals, wood, and, more recently, biological tissues.
[0006] It is known that monomeric forms of α-cyanoacrylates are extremely reactive, polymerizing rapidly in the presence of even minute amounts of an initiator, including moisture present in the air or on moist surfaces such as animal (including human) tissue. Monomers of α-cyanoacrylates are anionically polymerizable or free radical polymerizable, or polymerizable by zwitterions or ion pairs to form polymers. Once polymerization has been initiated, the cure rate can be very rapid.
[0007] Medical applications of 1,1-disubstituted ethylene adhesive compositions include use as an alternate or an adjunct to surgical sutures and/or staples in wound closure, as well as for covering and protecting surface wounds such as lacerations, abrasions, burns, stomatitis, sores, minor cuts and scrapes, and other wounds. When an adhesive is applied to surfaces to be joined, it is usually applied in its monomeric form, and the resultant polymerization gives rise to the desired adhesive bond.

The cyanoacrylate adhesive forms a matrix for the therapeutic agent, with the therapeutic agent being released in vivo over time from the matrix during biodegradation of the polymer.
[0009] U.S. Pat. No. 5,762,955 to Smith discloses a treatment for healthy, damaged, diseased, or infected biological tissue by applying a bioadhesive coating in conjunction with a medication. The treatment is directed, in part, to treating external biological tissue that may be affected by harmful afflictions such as bruises, burns, dermatological afflictions, infections, gashes, wounds, herpes sores, canker sores, or intra-oral lesions, and skin cancers such as leukemia. Smith further discloses several medications that may be used including corticosteroids, fluoroouracil, obtundants, anesthetics, antibiotics, fungicides, anti-inflammatory agents, antibacterial agents, antiseptic agents, and other medications or combinations of medications used in processes for healing tissue, promoting or preventing blood clotting, destroying cancer cells, palliative treatments and killing of bacteria or viruses.

No. 4,880,416 to Horiuchi et al., discloses a dermal bandage of a preformed film-like adhesive material for preventing dermally applied ointments, creams, solutions, powders, etc. from falling off, and for delivering drugs, such as anti-fungal agents, to affected parts of the skin. U.S. Pat. Nos. 5,716,607 and 5,716,608, both to Byram et al., disclose the use of cyanoacrylate adhesives to prevent ionization radiation damage to skin. Such damage is prevented by applying the cyanoacrylate polymer to the skin to be protected. U.S. Pat. No. 5,653,769 to Barkey, Jr., et al., discloses protecting skin areas from irritation due to contact with artificial devices such as prosthetics, bandages and casts by applying a cyanoacrylate polymer to the desired skin areas that otherwise would be prone to ulceration or irritation by the devices.
[0011] U.S. Pat. No. 4,287,177 to Nakashima et al. discloses a protective covering material for forming a film or coat on the skin or wound surface, wherein the film may contain an anti-fungal agent that is controllably released when the composition is placed in contact with the skin. U.S. Pat. Nos. 5,684,042; 5,753,699; 5,762,919; 5,783,177; and 5,811,091 to Greffet al. disclose a cyanoacrylate composition with a compatible anti-fungal agent to form an anti-fungal polymeric cyanoacrylate film to be applied on mammalian skin as wound dressings, wound bandages, surgical incise drapes, wound closure materials and the like.
[0012] Tinea cruris, also referred to generally as jock itch or ringworm of the groin, is a fungal infection or dermatophytosis of the groin, perineum and perineal regions, generally seen in males, and sometimes spreading to contiguous areas, generally caused by fungal species such as those of Microsporum, Trichophyton, and Epidermophyton, particularly by the fungal species of Trichophyton and Epidermophyton. The condition generally includes severely pruritic, sharply demarcated lesions with a raised erythematous margin and thin, dry scaling. Tinea cruris often accompanies tinea pedis, or Athlete's Foot.
[0013] Physicians commonly prescribe medications in the form of powders, aerosols, liquids or creams for the treatment of tinea cruris. Such medications are also commonly obtained by individuals “over-the-counter” for treatment of the same skin condition. The source of the affliction often is a public safety and health concern, as the occurrence of tinea cruris is higher in public areas such as locker rooms, public showers, sports facilities, and the like.
[0014] Often the condition occurs on the skin areas of the groin, perineum and perineal regions that are prone to higher levels of moisture and that come into frequent frictional contact with a patient's clothing or with other skin surfaces. As a result of this frictional contact, as well as contact with clothing and the like, topically applied medications can be more easily removed from the affected areas of a patient's skin. Moreover, the topically applied medications are more prone to the affects of moisture that is present at the affected area of skin. These difficulties mean that treatment is significantly reduced, because the medication is not held in place for a sufficient time. As a result, the efficacy of the treatment is significantly reduced, and patients must frequently reapply medications so that the affected area receives proper treatment. Furthermore, the inconvenience of bandages due to constant or frequent movement and flexing of the skin, the small surface area usually involved, friction and moisture, make bandages impractical for minimizing frictional contact that occurs at the affected areas of a patient's skin, as well as impractical as a means to hold the medication in place for longer periods of time.
[0015] In addition, conventional treatment regimens for tinea cruris continue to pose significant public health and safety concerns. Because conventional treatments have the above-described problems of being easily removed from the afflicted skin and being susceptible to moisture, there is a much greater chance that the fungal infection can be spread. This spread of the fungus can be either to other parts of the same patient's body, or to other individuals.
[0016] Despite the known use of adhesives, such as described above, such adhesives have not been used in the treatment of tinea cruris. Instead, the majority of tinea cruris treatments currently on the market include topically applied medications that have the problems of being easily removed from the application site, being prone to moisture effects, and resulting in higher spread or transmission rates. Therefore, there is a need for an alternative tinea cruris treatment that remains at the application site for longer periods, that reduces the spread or transmission of the fungal infection, and that provides fast, effective relief from the symptoms of tinea cruris.
SUMMARY OF THE INVENTION
[0017] The present invention provides methods for preventing and/or treating tinea cruris by applying a monomeric adhesive composition to the affected area, or to areas that are prone to infection. The monomeric adhesive composition of the present invention preferably comprises a polymerizable 1,1-disubstituted ethylene monomer such as a cyanoacrylate monomer, that may include or be accompanied by an additional anti-fungal agent. The composition reduces moisture contact with the affected skin area, keeps any active ingredients in contact with the affected skin area for a longer time, provides fast and effective treatment of tinea cruris, and can act to prevent infection in the first instance, or prevent the spread of an infection to other areas.
[0018] The present invention provides an unexpected treatment or prevention composition and method for tinea cruris, because polymerizable monomers such as 1,1-disubstitutyed ethylene monomers and cyanoacrylates have not previously been used to treat or prevent such skin conditions. Moreover, while such polymerizable monomers have been variously used on other parts of the body, such as for sealing open wounds, their use for treating or preventing tinea cruris, on areas of skin in the groin and surrounding areas, is an entirely and new and unexpected use of the materials.
[0019] The present treatment for or prevention of tinea cruris is advantageous for several reasons. First, because tinea cruris affects the skin in a patient's groin and surrounding areas, it is often very difficult for the patient to keep a treatment agent in contact with the affected skin area for an extended period of time. This is either because frictional contact with the affected area tends to disturb any applied active agents, or because higher levels of moisture present in the area tend to affect or likewise disturb the applied agent. Furthermore, because the treatment and prevention methods of the present invention provide a stronger physical barrier at the affected skin area, the risks of spread or transmission of the fungal infection, either to other areas of the patient's body or to other individuals, is significantly decreased. The present invention thus provides significant public health benefits.
[0020] Because cyanoacrylates tend to polymerize rapidly to form a relatively robust polymerized film, cyanoacrylates applied to an affected area of a patient's groin (or to an area prone or susceptible to infection) can provide fast, effective protection over the affected area and other skin surfaces. By protecting the affected area from moisture and frictional contact, the cyanoacrylate compound can hold any applied active agents in place for a longer period of time and can accordingly significantly increase the time of exposure of an applied medication to the affected area, ensure more effective treatment, and minimize the possibility of re-infection or transmission of the fungal infection to other areas of the patient's body or to other individuals. Likewise, the same benefits can be obtained by applying the composition of the present invention to an area prone or susceptible to infection, which in turn aids in preventing spread or transmission of the infection.
[0021] In addition to forming a stronger barrier to keep moisture away from the affected area while maintaining active agents in contact with the area, cyanoacrylate compounds are also desirable for the treatment or prevention of tinea cruris because of their inherent anti-fungal properties. In laboratory tests, it has been discovered that at least some cyanoacrylate compounds or formulations, even in the absence of an added anti-fungal agent, appears to inhibit fungal infections. Because of this anti-fungal property, such cyanoacrylate compounds and formulations may be especially desirable for treating or preventing tinea cruris, even without the introduction or pre-application of other anti-fungal agents. Moreover, the anti-fungal properties of such cyanoacrylate compounds and formulations may also be beneficial in instances where an anti-fungal agent is applied before, or together with, the cyanoacrylate, because the cyanoacrylate can continue to provide its anti-fungal effect even after the applied anti-fungal agent has been completely absorbed or used up.
[0022] In addition, cyanoacrylate compounds are also useful as anti-fungal agent carriers or delivery agents. In this capacity, the cyanoacrylate compound provides the same protective and anti-fungal benefits, but also offers the added benefit of enhancing the treatment of the affected area by controllably releasing an anti-fungal agent to the affected area, or providing prolonged preventative benefits to an applied area by controllably releasing an anti-fungal agent to the area.
[0023] The present invention also provides various applicators that are suitable for applying the adhesive composition.
DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
[0024] This invention is directed to methods of treating tinea cruris, commonly known as Jock Itch, by applying a monomeric adhesive composition to an afflicted area of a patient's skin, in particular the groin, perineum and perineal regions. This invention is also directed to methods of preventing tinea cruris by applying a monomeric adhesive composition to an area of a patient's skin that is prone or susceptible to such infection.
[0025] According to embodiments of the present invention, the adhesive composition can be applied alone, or it can be applied subsequent to or concurrent with the application of a separate anti-fungal agent. Furthermore, in embodiments, the cyanoacrylate composition can itself include an anti-fungal agent in addition to polymerizable monomer.
[0026] According to the present invention, “treat” (or other forms of the word such as “treating” and “treatment”) refers to employment of the methods against an established fungal infection. “Treat” thus encompasses both amelioration of effects of the fungal infection, such as by reducing swelling, irritation, pain and the like, and active reduction of the infection such as by killing the fungus and preventing re-growth of the fungus at an infected area.
[0027] According to the present invention, “prevent” (or other forms of the word such as “preventing” and “prevention”) refers to employment of the methods against a subsequent fungal infection, such as at areas of skin that are prone or susceptible to fungal infection. “Prevent” thus encompasses both prevention of spread of an established fungal infection, as well as prevention of infection in the first instance on the particular patient.
[0028] In embodiments of the invention, an adhesive composition can be used alone for treating or preventing tinea cruris. In such embodiments, a patient or care-provider simply applies the composition to an area of the skin, such as the groin, perineum and perineal regions, afflicted with tinea cruris, or to an area where prevention of infection is desired. The composition then is permitted to polymerize to form a robust polymeric coating that effectively covers and protects the affected or applied area of the patient's skin. Anti-fungal properties of the composition may inhibit or kill microbes, and the robust polymeric coating that the composition forms protects the area from frictional contact with clothing or other skin surfaces so that prolonged treatment or prevention can be achieved.
[0029] Preferably, the composition is applied in a sufficient amount to entirely cover the desired area, which generally would correspond to an affected area where tinea cruris is present, or to an areas that is prone or susceptible to tinea cruris. In embodiments, the composition covers an additional area around the desired area, for example to prevent further infection.
[0030] According to the present invention, the adhesive composition is preferably permitted to substantially or fully polymerize to form a polymer film before the treated area is permitted to contact other surfaces. Thus, for example, when the composition is applied to the groin, the thighs and other skin areas are preferably kept separated from each other until the composition has substantially or fully polymerized, to prevent bonding the thighs and other skin areas together.
[0031] In further embodiments of the present invention, the adhesive composition can be applied over a medicament for treating or preventing tinea cruris. The medicament in this embodiment is not particularly limited, and can include any of the available medicaments for the skin condition. The medicament can also be, or comprise, any suitable anti-fungal agent, as described below. In this embodiment, the medicament can be first applied to the affected or desired area, followed by application of a polymerizable adhesive composition. The medicament can be in any suitable form, including liquid, solid, powder, cream or the like, and can include only a medicament or can include other suitable additives such as diluents, carriers or the like. Where the medicament is in a liquid or a semi-liquid form, it is preferred that the medicament be permitted to dry, substantially or completely, prior to application of the adhesive composition. However, the adhesive composition can also be immediately applied over the applied medicament, or can be applied prior to drying of the medicament, if desired.
[0032] In embodiments of the present invention, an appropriate, preferably monomer-compatible, anti-fungal agent can be mixed with the polymerizable adhesive composition and a resultant composition applied to the affected or desired area. In this embodiment, the anti-fungal agent can be mixed with the polymerizable adhesive composition during manufacture (i.e. prior to packaging the materials), or immediately prior to use. However, the present invention is not limited to such embodiments. Thus, for example, the anti-fungal agent need not be monomer-compatible. In these embodiments, the anti-fungal agent can be mixed or combined with the polymerizable adhesive composition, usually just prior to application, and a resultant composition applied to the affected or desired area
[0033] In further embodiments of the present invention the anti-fungal agent may also serve as a polymerization initiator or a stabilizer. Thus, the anti-fungal agent can provide not only a biological activity, but a chemical one as well.
[0034] Anti-fungal agents that also serve as polymerization initiators can initiate and/or accelerate the polymerization of the composition when applied to an affected or desired area of skin. Accelerated polymerization reduces the waiting time necessary after application, and makes the composition more convenient to apply. Suitable anti-fungal agents that can also serve as initiators include, but are not limited to, certain acidic and quaternary ammonium compounds. In embodiments where the anti-fungal agent also acts as a polymerization initiator or rate modifier, the present invention provides the additional advantage of not requiring that a further, separate polymerization initiator or rate modifier be used. Furthermore, in these embodiments, the anti-fungal agent is preferably located in a non-contacting relationship with the adhesive composition prior to use, so that premature polymerization of the adhesive composition does not occur.
[0035] Anti-fungal agents that also serve as stabilizers can extend the useful life of the composition. By increasing the useful life of the composition, the composition can be stored and packaged for longer periods of time without the risk of premature polymerization. Suitable anti-fungal agents that can also serve as stabilizers can include, but are not limited to, certain acidic and phenolic compounds such as phenolic antioxidants. In embodiments where the anti-fungal agent also acts as a stabilizer for the adhesive composition, the present invention provides the additional advantage of not requiring that a further, separate stabilizer be used. Furthermore, in these embodiments, the anti-fungal agent is preferably located in a contacting relationship with the adhesive composition, such as being mixed with the adhesive composition, prior to use.
[0036] Although a mixture of anti-fungal agent and cyanoacrylate, according to the present invention, is not limited to a specific ratio of anti-fungal agent to cyanoacrylate, the anti-fungal agent is preferably present in an effective amount, preferably a therapeutically effective amount for treating or preventing the tinea cruris.
[0037] When mixed or combined immediately prior to use, the anti-fungal agent can be mixed with the polymerizable cyanoacrylate composition in a suitable container and thereafter applied. Alternatively, mixing can be conducted during the application process, for example by using an applicator that is loaded with anti-fungal agent, which thereby mixes the agent with the adhesive composition during application.
[0038] Suitable anti-fungal agents include, but are not limited to, known agents such as parabens, cresols, azoles, allylamines, pollyenes, acidics, mercurials, quaternary ammonium compounds, other agents, non-polymer-stabilized compounds, i.e., that are not complexed with or otherwise part of a polymer species, mixtures thereof, and the like. Such anti-fungal agents should preferably be present in a therapeutically effective amount, particularly in cases where higher amounts may otherwise be toxic to the patient.
[0039] For example, suitable parabens include, but are not limited to, alkyl parabens and salts thereof, such as methylparaben, methylparaben sodium, ethylparaben, propylparaben, propylparaben sodium, butylparaben, and the like. Butyl-paraben is especially preferred as it can also act as a stabilizer for certain polymerizable monomers, such as cyanoacrylate monomers, in the adhesive composition. Suitable cresols include, but are not limited to, cresol, chlorocresol, and the like. Suitable azoles include, but are not limited to, voriconazole, ketoconazole, fluconazole, itraconazole, miconazole, clotrimazole, saperconazole, neticonazole, oxiconazole, isoconazole, sulconazole, tercanazole, tioconazole, and the like. Suitable allylamines include, but are not limited to, naftifine, SF86-327, and the like. Suitable polyenes include, but are not limited to, nyastatin, amphotericin B, pimaricin, and the like. Suitable acidics include, but are not limited to, benzoic acid and salts thereof, sorbic acid and salts thereof, propionic acids and salts thereof, boric acid and salts thereof, dehydroacetic acid, sulphurous and vanillic acids, and alkyl esters of pararhydrobenzoic acid. Suitable mercurials include but are not limited to, thiomersal, phenylmercuric acetate and nitrate, nitromersol and sodium ethylmercurithiosalicylate. Suitable quaternary ammonium compounds include, but are not limited to, benzalkonium chloride, cetylpyridinium chloride, benzethonium chloride, and cetyltrimethyl ammonium bromide. Other known agents that can be used include, but are not limited to, hydroquinone, pyrocatechol, resorcinol, 4-n-hexyl resorcinol, captan (i.e., 3a,4,7,7a-tetrahydro-2-((trichloromethyl)thio)-1H-isoindole-1,3(2H)-dione), benzalkonium chloride, benzalkonium chloride solution, benzethonium chloride, benzoic acid, benzyl alcohol, cetylpyridinium chloride, chlorobutanol, dehydroacetic acid, o-phenylphenol, phenol, phenylethyl alcohol, potassium benzoate, potassium sorbate, sodium benzoate, sodium dehydroacetate, sodium propionate, sorbic acid, thimerosal, thymol, chlorothymol, alcohols, chlorobutanol, phenoxy-2-ethanol, benzyl alcohol, β-phenylethyl alcohol, chlorhexidine, 6-acetoxy-2,4-dimethyl-m-dioxane 2, 4,4′trichloro-2′-hydroxy-diphenylether, imidizoldinylether urea compound, bromo-2-nitropropanediol-1,3 5-bromo-5-nitrol-1,3dioxane 2-methyl 1-4-isothiazolin-3-one and 5 chloro derivative 1-(3-chloroallyl)-3,5,7-triazo 1-azoniaadamantane chloride (Dowicil 200), phenylmercuric compounds such as phenylmercuric borate, phenylmercuric nitrate and phenylmercuric acetate, formaldehyde, formaldehyde generators such as the preservatives Germall II® and Germall 115® (imidazolidinyl urea, available from Sutton Laboratories, Charthan, N.J.), morpholines, salicylic and benzoic acids, sodium and potassium iodides, flucytosine, 5-flucytosine, griseofulvin, terbinafine, cidofovir, famicoclovir, valacyclovir, echinocandins, pneumocandins, pradimicins, benanomicins, nikkomycins, amorolfine, polyoxins, duanorubicin citrate, doxorubicin hydrocholride, tolnaftate, ciclopirox, butenafine, and ergestrol biosynthesis inhibitors.
[0040] Non-polymer-stabilized compounds, i.e., that are not complexed with or otherwise part of a polymer species, which can be either soluble or insoluble in the monomeric composition, can also be used. Where the compounds are insoluble in the monomeric composition, they must generally be capable of releasing species, such as ions, which are soluble in the monomer composition and provide the anti-fungal effect. Thus such compounds either themselves are, or provide, the anti-fungal agent. Such suitable non-polymer-complexed materials include, but are not limited to, metals and metal compounds. Examples of such metal compounds or elemental metals include, but not limited to, mercurial compounds, such as phenolmercuric chloride, phenolmercuric acetate, acetomeroctol, nitromersol, thimerosal, mercurochrome, mercuric chloride, and mercuric iodide; elemental metals, such as silver and copper; and metal compounds, such as copper chloride, copper sulfate, copper peptides, zinc chloride, zinc sulfate, zinc salts of cyanoacrylic acid, zinc salts of cyanoacetic acid, zinc salts of dicyanoglutaric acid, zinc salts of rosin, zinc oxide, zinc salts of polycyanoacrylic acid, zinc salts of polyacrylic acid, zinc bacitracin, zinc salicylate, zinc stearate, zinc citrate, zinc lactate, silver nitrate, silver iodide, silver acetate, silver benzoate, silver carbonate, silver chloride, silver citrate, silver oxide, silver sulfate, and tincture of iodine; as well as mixtures thereof and the like. Copper peptides are discussed, for example, in “Copper: An Essential Element for Life,” ProCyte Corporation, available at http://www.humatech.com/technology.html (Oct. 28, 1999), the entire disclosure of which is incorporated herein by reference. Further information on anti-fungal activities of metals can be found, for example, in S. Seymour Block, Disinfection, Sterilization and Preservation,3rdEd.,Philadelphia:Lea & Febiger, 1983, the entire disclosure of which is incorporated herein by reference. The ions from the metal, which constitute the anti-fungal agent, diffuse into and through the adhesive composition.
[0041] Other suitable anti-fungal agents include the various compounds identified as such in The Merck Index,12thEd. (1996), incorporated herein by reference. Such agents include acrisorein, 3-amino-4-hydroxybutyric acid, ammonium mercuric chloride, amorolfine, amphotericin B, anthralin, azaserine, benzoic acid, bifonazole, biphenamine, boric acid, bromosalicylchloranilide, buclosamide, butenafine, butoconazole, calcium propionate, candicidin, chlordantoin, chlormidazole, chlorphenesin, chlorquinaldol, ciclopirox, cloconazole, clotrimazole, cloxyquin, coparaffinate, m-cresyl acetate, cupric sulfate, dermostatin, diamthazole dihydrochloride, econazole, enilconazole, etisazol, exalamide, fenticonazole, filipin, fluconazole, flucytosine, flutrimazole, fungichromin, griseofulvin, hachimycin, halethazole, hamycin, hexetidine, isoconazole, itraconazole, ketoconazole, lanoconazole, loflucarban, lucensomycin, Magenta I, mepartricin, 2-(methoxymethyl)-5-nitrofuran, miconazole, monensin, myxin, naftifine, natamycin, neomycin undecylenate, nifuratel, nystatin, oligomycins, omoconazole, ontianil, oxiconazole nitrate, pecilocin, perimycin, phenylmurcuric nitrate (basic), potassium iodide, propionic acid, pyrithione, pyrrolnitrin, rubijervine, salicylanilide, salicylic acid, saperconazole, sertaconzole, siccanin, sodium propionate, sulbentine, sulconazole, tenonitrozole, terbinafine, terconazole, thimerosal, tioconazole, tolciclate, tolindate, tolnaftate, triacetin, 2,4,6-tribromo-m-cresol, tubercidin, ujothion, undecylenic acid, viridin, zinc propionate, mixtures thereof, and the like.
[0042] In embodiments of the present invention, the monomer composition can also be applied in conjunction with one or more conventional skin care additives. Suitable skin care additives that are typically used in the treatment of tinea cruris and that can be applied in place of or in conjunction with the monomer composition and/or the anti-fungal agent of the present invention include, but are not limited to, miconazole nitrate, povidone iodine complex, cliquinol, haloprogin, tolnaftate and undecylenic acid, mixtures thereof, and the like.
[0043] In addition, in embodiments where monomer additives including, but not limited to those listed above, are insoluble with the monomer composition, the additive can be applied to a skin area before applying the monomer composition. In such embodiments, the additive and the monomer composition can be provided, for example, in separate packages in a kit.
[0044] In other embodiments, where such additives are soluble with the monomer composition, the additives can be combined with the monomer composition during manufacture of the composition. Moreover, in cases where the additive is soluble with the monomer composition, the additive can be applied before the monomer composition is applied, it can be pre-mixed with and applied together with the monomer composition, it can be mixed together with the monomer composition immediately before application, or it can even be applied after the monomer composition has been applied. As a result, in cases where a soluble additive is to be applied, the additive and the composition can be provided in a kit where the additive and the monomer composition are pre-mixed, or the additive and the monomer composition can be provided separately to be applied separately or mixed together immediately prior to, during, or after application.
[0045] Although a mixture of additive and cyanoacrylate, according to the present invention is not limited to a specific ratio of additive to cyanoacrylate, the additive is preferably present in an effective amount, and preferably in a therapeutically effective amount.
[0046] When mixed immediately prior to use, the additive can be mixed with the polymerized cyanoacrylate composition in a suitable container and thereafter applied. Alternatively, mixing can be conducted during the application process, for example by using an applicator loaded with skin care additive, which thereby mixes the additive with the adhesive composition during application.
[0047] In addition, as discussed above with respect to suitable anti-fungal agents, various skin care additives may also serve as polymerization initiators or rate modifiers. Also, suitable skin care additives may serve as stabilizers for the adhesive composition.
[0048] In embodiments, the monomer composition and/or its packaging can be sterilized. However, sterilization is by no means required, particularly in view of the fact that most commercially available products for the treatment of tinea cruris are not sterilized. Furthermore, whether or not the composition and container is sterilized, the composition can further include one or more suitable preservative, as described below.
[0049] Sterilization of the monomer composition and/or its packaging can be accomplished by techniques known to the skilled artisan, and is preferably accomplished by methods including, but not limited to, chemical, physical, and/or irradiation methods. Examples of chemical methods include, but are not limited to, exposure to ethylene oxide or hydrogen peroxide vapor. Examples of physical methods include, but are not limited to, sterilization by heat (dry or moist) or retort canning. Examples of irradiation methods include, but are not limited to, gamma irradiation, electron beam irradiation, and microwave irradiation. A preferred method is electron beam irradiation, as described in U.S. patent application Ser. No. 09/025,472, filed on Feb. 18, 1998, the entire disclosure of which is incorporated herein by reference. The composition should also show low levels of toxicity to living tissue during its useful life. In preferred embodiments of the present invention, the composition is sterilized to provide a Sterility Assurance Level (SAL) of at least 10−3. In embodiments, the Sterility Assurance Level may be at least 10−4, or may be at least 10−5, or may be at least 10−6.
[0050] The monomer (including prepolymeric) adhesive composition may include one or more polymerizable monomers. Preferred monomers that may be used in this invention are readily polymerizable, e.g. anionically polymerizable or free radical polymerizable, or polymerizable by zwitterions or ion pairs to form polymers. Such monomers include those that form polymers, that may, but do not need to, biodegrade. Such monomers are disclosed in, for example, U.S. Pat. Nos. 5,328,687 and 5,928,611 to Leung et al., U.S. patent application Ser. No. 09/430,177, filed on Oct. 29, 1999, and U.S. patent application Ser. No. 09/471,392 filed Dec. 23, 1999, which are hereby incorporated in their entirety by reference herein.

EXAMPLES
Example 1
[0065] A 2-octyl cyanoacrylate monomer composition is prepared by adding 30 mg of haloprogin, an anti-fungal agent, to 2 mL of 2-octyl cyanoacrylate monomer. The mixture is sealed in a glass vial and stirred.
[0066] The characteristics of the composition are observed at about one minute after preparation and later at least twenty-four hours after preparation. The results of the observations show that the solution remains clear, indicating that haloprogin is soluble in the monomer and does not cause premature polymerization.
[0067] The composition is then applied to an affected area of skin showing the characteristics of tinea cruris. The monomer composition polymerizes in under one minute, resulting in a polymerized film of material covering the affected area. The polymerized film will remain in place for at least three days.
[0068] While the invention has been described with reference to preferred embodiments, the invention is not limited to the specific examples given, and other embodiments and modifications can be made by those skilled in the art without departing from the spirit and scope of the invention.
