ADHESIVE TREATMENT FOR TINEA
CRURIS
BACKGROUND OF THE INVENTION
1. Field of Invention
The present invention relates to treatment and prevention
of tinea cruris, commonly known as Jock Itch.
2. Description of Related Art
Monomer and polymer adhesives are used in both indus-
trial (including household) and medical applications.
Included among these adhesives are the 1,1-disubstituted
ethylene monomers and polymers, such as the
ot-cyanoacrylates. Since the discovery of the adhesive prop-
erties 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 ot-cyanoacrylate adhe-
sives the primary choice for numerous applications such as
bonding plastics, rubbers, glass, metals, wood, and, more
recently, biological tissues.
It is known that monomeric forms of ot-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 ot-cyanoacrylates
are anionically polymerizable or free radical polymerizable,
or polymerizable by zwitterions or ion pairs to form poly-
mers. Once polymerization has been initiated, the cure rate
can be very rapid.
Medical applications of 1,1-disubstituted ethylene adhe-
sive 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 mono-
meric form, and the resultant polymerization gives rise to the
desired adhesive bond.
U.S. Pat. Nos. 5,514,371, 5,514,372, 5,575,997, 5,624,
669, and 5,582,834 to Leung et al. disclose the addition of
a therapeutic agent in a cyanoacrylate composition. 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.
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 medi-
cation. 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, fiuoroouracil, obtundants, anesthetics,
antibiotics, fungicides, anti-inflammatory agents, antibacte-
rial 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.
U.S. Pat. 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 pre-
vented 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.
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 poly-
meric cyanoacrylate film to be applied on mammalian skin
as wound dressings, wound bandages, surgical incise drapes,
wound closure materials and the like.
Tinea cruris, also referred to generally as jock itch or
ringworm of the groin, is a fungal infection or dermatophy-
tosis 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, particu-
larly by the fungal species of Trichophyton and Epidermo-
phyton. The condition generally includes severely pruritic,
sharply demarcated lesions with a raised erythematous mar-
gin and thin, dry scaling. Tinea cruris often accompanies
tinea pedis, or Athlete’s Foot.
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.
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 sig-
nificantly 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 fre-
quently 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 mini-
mizing 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.
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
US 6,585,967 B2
3
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.
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 treat-
ments 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
The present invention provides methods for preventing
and/or treating tinea cruris by applying a monomeric adhe-
sive 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 addi-
tional anti-fungal agent. The composition reduces moisture
contact with the affected skin area, keeps any active ingre-
dients 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.
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.
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.
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 effec-

tive 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.
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 labora-
tory 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 espe-
cially 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.
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 pro-
viding prolonged preventative benefits to an applied area by
controllably releasing an anti-fungal agent to the area.
The present invention also provides various applicators
that are suitable for applying the adhesive composition.
DETAILED DESCRIPTION OF PREFERRED
EMBODIMENTS
This invention is directed to methods of treating tinea
cruris, commonly known as Jock Itch, by applying a mono-
meric 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.
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.
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.
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
US 6,585,967 B2
5
both prevention of spread of an established fungal infection,
as well as prevention of infection in the first instance on the
particular patient.
In embodiments of the invention, an adhesive composi-
tion 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.
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 addi-
tional area around the desired area, for example to prevent
further infection.
According to the present invention, the adhesive compo-
sition is preferably permitted to substantially or fully poly-
merize 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.
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, substan-
tially 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.
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 poly-
merizable adhesive composition, usually just prior to
application, and a resultant composition applied to the
affected or desired area
In further embodiments of the present invention the
anti-fungal agent may also serve as a polymerization initia-

tor or a stabilizer. Thus, the anti-fungal agent can provide not
only a biological activity, but a chemical one as well.
Anti-fungal agents that also serve as polymerization ini-
tiators 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 inven-
tion 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.
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 adhe-
sive composition, prior to use.
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.
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 there-
after 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.
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.
For example, suitable parabens include, but are not lim-
ited 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,

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 gener-
ally 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,

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.
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 compo-
sition can be provided, for example, in separate packages in
a kit.
In other embodiments, Where such additives are soluble
with the monomer composition, the additives can be com-
bined 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
US 6,585,967 B2
9
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.
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 thera-
peutically effective amount.
When mixed immediately prior to use, the additive can be
mixed with the polymerized cyanoacrylate composition in a
suitable container and thereafter applied. Alternatively, mix-
ing 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.
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.
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.
Sterilization of the monomer composition and/or its pack-
aging 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 hydro-
gen 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 refer-
ence. 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 103. In embodiments, the Sterility Assurance Level
may be at least 104, or may be at least 105, or may be at
least 106.
The monomer (including prepolymeric) adhesive compo-
sition 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 appli-

EXAMPLES
Example 1
A 2-octyl cyanoacrylate monomer composition is pre-
pared 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.
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 halo-
progin is soluble in the monomer and does not cause
premature polymerization.
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.
