A foamble pharmaceutical carrier includes about 50% to about 98% of a polar solvent selected from the group consisting of a polyol and PEG; 0% to about 48% of a secondary polar solvent; about 0.2% to about 5% by weight of a surface-active agent; about 0.01% to about 5% by weight of at least one polymeric agent; and a liquefied or compressed gas propellant at a concentration of about 3% to about 25% by weight of the total composition.
Description
BACKGROUND OF THE INVENTION

This invention relates to foamable pharmaceutical and cosmetic compositions.


External topical administration is an important route for the administration of drugs in disease treatment. Many groups of drugs, including, for example, antibiotic, anti-fungal, anti-inflammatory, anesthetic, analgesic, anti-allergic, corticosteroid, retinoid and anti-proliferative medications are preferably administered in hydrophobic media, namely ointment. However, ointments often form an impermeable barrier, so that metabolic products and excreta from the wounds to which they are applied are not easily removed or drained away. Furthermore, it is difficult for the active drug dissolved in the carrier to pass through the white petrolatum barrier layer into the wound tissue, so the efficacy of the drug is reduced. In addition, ointments and creams often do not create an environment for promoting respiration of the wound tissue and it is not favorable to the normal respiration of the skin. An additional disadvantage of petroleum jelly-based products relates to the greasy feeling left following their topical application onto the skin, mucosal membranes and wounds.


Foams and, in particular, foams that are substantially based on non-aqueous solvents are complicated systems which do not form under all circumstances. US Pat. Appl. No. 20050031547 relates to stable oleaginous cosmetic or therapeutic foam compositions containing certain active agents, having unique therapeutic properties and methods of treatment using such compositions. The foamable carrier includes at least one solvent selected from a hydrophobic solvent, a silicone oil, an emollient, a co-solvent, and mixtures thereof, wherein the solvent is present at a concentration of about 70% to about 96.5% by weight of the total composition, at least a non-ionic surface-active agent at a concentration of about 0.1% to less than about 10% by weight of the total composition; at least one gelling agent at a concentration of about 0.1% to about 5% by weight of the total composition; a therapeutically effective amount of at least one active agent; and at least one liquefied or compressed gas propellant, at a concentration of about 3% to about 25% by weight of the total composition.


WO 00/09082 teaches an anhydrous cleansing composition for topical application to human skin, comprising an ionic surfactant, glycerine, propylene glycol and water insoluble benefit agents. According to the examples of WO 00/09082, the concentration of the ionic surfactant is in the range of 18-22%.


U.S. Pat. No. 6,765,001 comprises a composition, method of enhancing potency and method of delivering corticosteroids in a vehicle comprising two or more penetration enhancers selected from the group consisting of diisopropyl adipate, dimethyl isosorbide, propylene glycol, 1,2,6-hexapetriol, and benzyl alcohol; and one or more of the group consisting of solvents and emulsifiers.


WO91/11991 teaches an essentially non-aqueous and non-oily foamable composition, that can be used for rectal administration of pharmaceuticals, comprising a liquid polar polyol or polyol mixture, a pharmaceutically active ingredient and at least one foam stabilizing and emulsifying surfactant. However, this foam composition is associated with disadvantages and the purposes of the present invention are not attained (see comparative example below).


There remains an unmet need for improved, easy to use, stable and non-irritating anti-infective foam formulations, intended for treatment of dermal and mucosal tissues. Particularly, there remains an unmet need for improved, easy to use, stable and non-irritating anti-infective foam formulations, with unique therapeutic properties.

DETAILED DESCRIPTION OF THE INVENTION

The present invention relates to a composition for use as foamable vehicle composition.


According to one or more embodiments of the present invention, the foamable carrier, includes:

    • a. about 50% to about 98% of a polar solvent selected from the group consisting of (1) a polyol; and (2) a polyethylene glycol;
    • b. 0% to about 48% of a secondary polar solvent;
    • c. about 0.2% to about 5% by weight of a surface-active agent;
    • d. about 0.01% to about 5% by weight of at least one polymeric agent; and
    • e. a liquefied or compressed gas propellant at a concentration of about 3% to about 25% by weight of the total composition.


      All % values are provided on a weight (w/w) basis.


Water, up to 25% of the composition, and more preferably up to 10%, and optional ingredients are added to complete the total mass to 100%. In certain cases, the composition contains two active agents that require different pH environments in order to remain stable. For example, corticosteroids are typically stable at acidic pH (they have a maximum stability at a pH of about 4-6) and vitamin D analogues are typically stable at basic pH (they have a maximum stability at pH values above about 8). In other cases, the active agent degrades in the presence of water, and therefore, in such cases the present of water in the composition is not desirable. Thus, in certain preferred embodiments, the composition is substantially non-aqueous. The term “substantially non-aqueous” is intended to indicate that the composition has a water content below about 5%, preferably below about 2%, such as below about 1.5%.


Upon release from an aerosol container, the foamable carrier forms an expanded foam suitable for the treatment of an infected surface and for topical administration to the skin, a body surface, a body cavity or a mucosal surface.


The identification of a “polar solvent”, as used herein, is not intended to characterize the solubilization capabilities of the solvent for any specific active agent or any other component of the foamable composition. Rather, such information is provided to aid in the identification of materials suitable for use as a part in the foamable compositions described herein.


Polyol


In an embodiment of the present invention, the polar solvent is a polyol. A polyol is an organic substance that contains at least two hydroxy groups in its molecular structure.


In one or more embodiments, the foamable carrier contains at least one diol (a compound that contains two hydroxy groups in its molecular structure). Examples of diols include propylene glycol (e.g., 1,2-propylene glycol and 1,3-propylene glycol), butanediol (e.g., 1,2-butanediol, 1,3-butanediol, 2,3-butanediol and 1,4-butanediol), butanediol (e.g., 1,3-butanediol and 1,4-butenediol), butynediol, pentanediol (e.g., pentane-1,2-diol, pentane-1,3-diol, pentane-1,4-diol, pentane-1,5-diol, pentane-2,3-diol and pentane-2,4-diol), hexanediol (e.g., hexane-1,6-diol hexane-2,3-diol and hexane-2,56-diol), octanediol (e.g., 1,8-octanediol), neopentyl glycol, 2-methyl-1,3-propanediol, diethylene glycol, triethylene glycol, tetraethylene glycol, dipropylene glycol and dibutylene glycol.


In one or more embodiments, the foamable carrier contains at least one triol (a compound that contains three hydroxy groups in its molecular structure), such as glycerin, butane-1,2,3-triol, butane-1,2,4-triol and hexane-1,2,6-triol.


In one or more embodiments, the polyol is a mixture of polyols. In one or more embodiments, the mixture of polyols contains at least one diol and at least one triol. According to certain embodiments the ratio between the diol and triol is between 9:1 and 1:1.


In one or more embodiments, part of mixture of polyols is a saccharide. Exemplary saccharides include, but are not limited to monosaccharide, disaccharides, oligosaccharides and sugar alcohols.


A monosaccharide is a simple sugar that cannot be hydrolysed to smaller units. Empirical formula is (CH2O)n and range in size from trioses (n=3) to heptoses (n=7). Exemplary monosaccharide compounds are ribose, glucose, fructose and galactose.


Disaccharides are made up of two monosaccharides joined together, such as sucrose, maltose and lactose.


A sugar alcohol (also known as a polyol, polyhydric alcohol, or polyalcohol) is a hydrogenated form of saccharide, whose carbonyl group (aldehyde or ketone, reducing sugar) has been reduced to a primary or secondary hydroxyl group. They are commonly used for replacing sucrose in foodstuffs, often in combination with high intensity artificial sweeteners to counter the low sweetness. Some exemplary sugar alcohols, which are suitable for use according to the present invention are mannitol, sorbitol, xylitol, maltitol, lactitol. (Maltitol and lactitol are not completely hydrogenated compounds—they are a monosaccharide combined with a polyhydric alcohol). Mixtures of polyols, including (1) at least one polyol selected from a diol and a triol; and (2) a saccharide are contemplated within the scope of the present invention.


Polyethylene Glycol


In an embodiment of the present invention, the polar solvent consists of a polymerized ethylene glycol, namely polyethylene glycol, which is also termed “PEG”. Exemplary PEGs are provided in the following table.

Thus, in an embodiment of the present invention, the PEG is selected from the group consisting of PEG 200, PEG 300, PEG 400, PEG 600, PEG 1000, PEG 4000, PEG 6000 and PEG 8000. The foamable carrier according to the present invention can contain a single PEG or a mixture of two or more PEGs. PEGs having molecular weight of more that about 1000 possess gelling properties; i.e., they increase the viscosity of a composition. Therefore, by combining PEGs with different molecular weights/melting points, one can attain varying levels of flowability as desirable for the treatment of a given target site. The concentration of the PEG should be in a level that results in viscosity, prior to filling of the composition into aerosol canisters, of less than 12,000 CPs, and more preferably, less than 10,000 CPs.


Secondary Polar Solvent


Optionally, a secondary polar solvent is added to the foamable composition of the present invention. The secondary polar solvent is selected from a variety of organic solvents that are typically miscible on both water and oil. Examples of polar solvent that can be contained in the foamable carrier of the present invention include dimethyl isosorbide, tetrahydrofurfuryl alcohol polyethyleneglycol ether (glycofurol), DMSO, pyrrolidones, (such as N-Methyl-2-pyrrolidone and 1-Methyl-2-pyrrolidinone), ethyl proxitol, dimethylacetamide (DMAc), PEG-type surfactants and alpha hydroxy acids, such as lactic acid and glycolic acid.


Solubilization and Penetration Enhancement


In many cases, polyols, PEGs and polar solvents possess a high solubilizing power and thus, they can enable increased concentrations of a pharmaceutical active agent. Polyols, PEGs and polar solvents are also known for their skin penetration enhancement properties. These properties enable high drug bioavailability in the target area of treatment, resulting in an enhanced therapeutic effect. Occasionally, combinations of a polyol, PEGs and a secondary polar solvent, exhibit an increased permeability across the skin, as suggested, for example, in Eur J Pharm Biopharm. 1998 November; 46(3):265-71.


Thus, in one or more embodiments, the foamable carrier contains (1) at least one polar solvent, selected from a polyol (selected from a diol and a triol) and PEG; and (2) at least one secondary polar solvent.


In one or more embodiments, the foamable carrier contains (1) a mixture of at least two polyols; and (2) at least one secondary polar solvent. In additional embodiments, the foamable carrier contains a mixture of at least one polyol and at least one PEG; yet in other embodiments the foamable carrier contains (1) a mixture of at least one polyol and at least one PEG and (2) at least one secondary polar solvent.


According to certain embodiments the ratio between the polyol and/or PEG and the secondary polar solvent is between 9:1 and 1:1.


In certain embodiments, the polyol is selected from the group consisting of propylene glycol, hexylene glycol and glycerin (and mixtures thereof); and the secondary polar solvent is selected from the group consisting of dimethyl isosorbide, diethylene glycol monoethyl ether, a liquid polyethylene glycol and glycofurol.


In certain embodiments, the foamable carrier contains (1) at least one polyol; and (2) dimethyl isosorbide.


Short chain alcohols, such as ethanol and propanol are known as polar solvents, however, according to one or more embodiments, the composition of the present invention is substantially alcohol-free, i.e., free of short chain alcohols. Short chain alcohols, having up to 5 carbon atoms in their carbon chain skeleton and one hydroxyl group, such as ethanol, propanol, isopropanol, butanol, iso-butanol, t-butanol and pentanol, are considered less desirable polar solvents due to their skin-irritating effect.


Thus, in certain embodiments, the composition is substantially alcohol-free and includes less than about 5% final concentration of lower alcohols, preferably less than about 2%, more preferably less than about 1%. However, in other embodiments, a short chain alcohol can be included in the composition, as long as the ratio between the short chain alcohol and the polyol is less than 1:4 by weight.


Polymeric Agent


The composition of the present invention contains a polymeric agent. It has been documented that the presence of a polymeric agent is necessary for the creation of foam, having fine bubble structure, which does not readily collapse upon release from the pressurized aerosol can. The polymeric agent serves to stabilize the foam composition and to control drug residence in the target organ. Preferably, the polymeric agent is soluble or readily dispersible in the polyol; or in the mixture of a polyol and an additional polar solvent.


Non-limiting examples of polymeric agents that are soluble or readily dispersible in propylene glycol are Hydroxypropylcellulose and carbomer (homopolymer of acrylic acid is crosslinked with an allyl ether pentaerythritol, an allyl ether of sucrose, or an allyl ether of propylene, such as Carbopol® 934, Carbopol® 940, Carbopo® 941, Carbopol® 980 and Carbopol® 981.


Other polymeric agents are suitable for use according to the present invention provided that they are soluble or readily dispersible in the polyol; or in the mixture of a polyol and an additional polar solvent, on a case by case basis.


Exemplary polymeric agents include, in a non-limiting manner, naturally-occurring polymeric materials, such as locust bean gum, sodium alginate, sodium caseinate, egg albumin, gelatin agar, carrageenin gum, sodium alginate, xanthan gum, quince seed extract, tragacanth gum, guar gum, cationic guars, hydroxypropyl guar gum, starch, amine-bearing polymers such as chitosan; acidic polymers obtainable from natural sources, such as alginic acid and hyaluronic acid; chemically modified starches and the like, carboxyvinyl polymers, polyvinylpyrrolidone, polyvinyl alcohol, polyacrylic acid polymers, polymethacrylic acid polymers, polyvinyl acetate polymers, polyvinyl chloride polymers, polyvinylidene chloride polymers and the like.


Additional exemplary polymeric agents include semi-synthetic polymeric materials such as cellulose ethers, such as methylcellulose, hydroxypropyl cellulose, hydroxypropyl methylcellulose, hydroxyethyl cellulose, hydroxy propylmethyl cellulose, methylhydroxyethylcellulose, methylhydroxypropylcellulose, hydroxyethylcarboxymethylcellulose, carboxymethyl cellulose, carboxymethylcellulose carboxymethylhydroxyethylcellulose, and cationic celluloses. Polyethylene glycol, having molecular weight of 1000 or more (e.g., PEG 1,000, PEG 4,000, PEG 6,000 and PEG 10,000) also have gelling capacity and while they are considered herein as “secondary polar solvents”, as detailed herein, they are also considered polymeric agents.


Mixtures of the above polymeric agents are contemplated.


The concentration of the polymeric agent should be selected so that the composition, after filling into aerosol canisters, is flowable, and can be shaken in the canister. In one or more embodiments, the concentration of the polymeric agent is selected such that the viscosity of the composition, prior to filling of the composition into aerosol canisters, is less than 12,000 CPs, and more preferably, less than 10,000 CPs.


Surface-Active Agent


The composition of the present invention further contains a surface-active agent. Surface-active agents (also termed “surfactants”) include any agent linking oil and water in the composition, in the form of emulsion. A surfactant's hydrophilic/lipophilic balance (HLB) describes the emulsifier's affinity toward water or oil. HLB is defined for non-ionic surfactants. The HLB scale ranges from 1 (totally lipophilic) to 20 (totally hydrophilic), with 10 representing an equal balance of both characteristics. Lipophilic emulsifiers form water-in-oil (w/o) emulsions; hydrophilic surfactants form oil-in-water (o/w) emulsions. The HLB of a blend of two emulsifiers equals the weight fraction of emulsifier A times its HLB value plus the weight fraction of emulsifier B times its HLB value (weighted average).


According to one or more embodiments the composition contains a single surface active agent having an HLB value between about 7 and 12, or more than one surface active agent and the weighted average of their HLB values is between about 7 and about 12.


Preferably, the composition of the present invention contains a non-ionic surfactant. Nonlimiting examples of possible non-ionic surfactants include polysorbates, such as polyoxyethylene (20) sorbitan monostearate (Tween 60) and poly(oxyethylene) (20) sorbitan monooleate (Tween 80); poly(oxyethylene) (POE) fatty acid esters, such as Myrj 45, Myrj 49, Myrj 52 and Myrj 59; poly(oxyethylene)alkylyl ethers, such as poly(oxyethylene)cetyl ether, poly(oxyethylene)palmityl ether, polyethylene oxide hexadecyl ether, polyethylene glycol cetyl ether, brij 38, brij 52, brij 56 and brij W1; sucrose esters, partial esters of sorbitol and its anhydrides, such as sorbitan monolaurate and sorbitan monolaurate; mono or diglycerides, isoceteth-20, and mono-, di- and tri-esters of sucrose with fatty acids (sucrose esters).


Non-limiting examples of non-ionic surfactants that have HLB of about 7 to about 12 include PEG 100 stearate (HLB=11), Laureth 4 (HLB=9.7) and cetomacrogol ether (e.g., polyethylene glycol 1000 monocetyl ether).


Yet, in additional embodiments, the composition contains a single surface active agent or a combination of surface active agents having an HLB values between about 9 and about 14; and in other embodiments, the composition contains one or more surface active agents, having an HLB value between about 2 and about 9.


In certain cases, the surface active agent is selected from the group of cationic, zwitterionic, amphoteric and ampholytic surfactants, such as sodium methyl cocoyl taurate, sodium methyl oleoyl taurate, sodium lauryl sulfate, triethanolamine lauryl sulfate and betaines.


In one or more embodiments of the present invention, the surface-active agent includes at least one non-ionic surfactant. Ionic surfactants are known to be irritants. Therefore, non-ionic surfactants are preferred in applications including sensitive tissue such as found in most mucosal tissues, especially when they are infected or inflamed. We have surprisingly found that non-ionic surfactants alone provide foams of excellent quality, i.e. a score of “E” according to the grading scale discussed herein below.


Thus, in a preferred embodiment, the surface active agent, the composition contains a non-ionic surfactant, or a mixture of non-ionic surfactants as the sole surface active agent. Yet, in additional embodiments, the foamable composition includes a mixture of at least one non-ionic surfactant and at least one ionic surfactant in a ratio in the range of about 100:1 to 6:1. In further embodiments, surface active agent comprises a combination of a non-ionic surfactant and an ionic surfactant, at a ratio of between 1:1 and 20:1. The concentration of the surface active agent is between about 0.1% and about 5%.


Hydrophobic Solvent


Optionally, the foamable carrier further contains at least one hydrophobic solvent. The identification of a “hydrophobic solvent”, as used herein, is not intended to characterize the solubilization capabilities of the solvent for any specific active agent or any other component of the foamable composition. Rather, such information is provided to aid in the identification of materials suitable for use as a part in the foamable compositions described herein.


A “hydrophobic solvent” as used herein refers to a material having solubility in distilled water at ambient temperature of less than about 1 gm per 100 mL, more preferable less than about 0.5 gm per 100 mL, and most preferably less than about 0.1 gm per 100 mL.


In one or more embodiments, the hydrophobic organic carrier is an oil, such as mineral oil, isopropyl palmitate, isopropyl isostearate, diisopropyl adipate, diisopropyl dimerate, maleated soybean oil, octyl palmitate, cetyl lactate, cetyl ricinoleate, tocopheryl acetate, acetylated lanolin alcohol, cetyl acetate, phenyl trimethicone, glyceryl oleate, tocopheryl linoleate, wheat germ glycerides, arachidyl propionate, myristyl lactate, decyl oleate, propylene glycol ricinoleate, isopropyl lanolate, pentaerythrityl tetrastearate, neopentylglycol dicaprylate/dicaprate, isononyl isononanoate, isotridecyl isononanoate, myristyl myristate, triisocetyl citrate, octyl dodecanol, unsaturated or polyunsaturated oils, such as olive oil, corn oil, soybean oil, canola oil, cottonseed oil, coconut oil, sesame oil, sunflower oil, borage seed oil, syzigium aromaticum oil, hempseed oil, herring oil, cod-liver oil, salmon oil, flaxseed oil, wheat germ oil, evening primrose oils; essential oils; and silicone oils, such as dimethicone, cyclomethicone, polyalkyl siloxanes, polyaryl siloxanes, polyalkylaryl siloxanes and polyether siloxane copolymers, polydimethylsiloxanes(dimethicones) and poly(dimethylsiloxane)-(diphenyl-siloxane)copolymers.


Foam Adjuvant


Optionally, a foam adjuvant is included in the foamable carriers of the present invention to increase the foaming capacity of surfactants and/or to stabilize the foam. In one or more embodiments of the present invention, the foam adjuvant agent includes fatty alcohols having 15 or more carbons in their carbon chain, such as cetyl alcohol and stearyl alcohol (or mixtures thereof). Other examples of fatty alcohols are arachidyl alcohol (C20), behenyl alcohol (C22), 1-triacontanol (C30), as well as alcohols with longer carbon chains (up to C50). Fatty alcohols, derived from beeswax and including a mixture of alcohols, a majority of which has at least 20 carbon atoms in their carbon chain, are especially well suited as foam adjuvant agents. The amount of the fatty alcohol required to support the foam system is inversely related to the length of its carbon chains. Foam adjuvants, as defined herein are also useful in facilitating improved spreadability and absorption of the composition.


In one or more embodiments of the present invention, the foam adjuvant agent includes fatty acids having 16 or more carbons in their carbon chain, such as hexadecanoic acid (C16) stearic acid (C18), arachidic acid (C20), behenic acid (C22), octacosanoic acid (C28), as well as fatty acids with longer carbon chains (up to C50), or mixtures thereof. As for fatty alcohols, the amount of fatty acids required to support the foam system is inversely related to the length of its carbon chain.


Optionally, the carbon atom chain of the fatty alcohol or the fatty acid may have at least one double bond. A further class of foam adjuvant agent includes a branched fatty alcohol or fatty acid. The carbon chain of the fatty acid or fatty alcohol also can be substituted with a hydroxyl group, such as 12-hydroxy stearic acid.


Additional Components


In an embodiment of the present invention, a composition of the present invention includes one or more additional components. Such additional components include but are not limited to anti perspirants, anti-static agents, buffering agents, bulking agents, chelating agents, cleansers, colorants, conditioners, deodorants, diluents, dyes, emollients, fragrances, hair conditioners, humectants, pearlescent aids, perfuming agents, permeation enhancers, pH-adjusting agents, preservatives, protectants, skin penetration enhancers, softeners, solubilizers, sunscreens, sun blocking agents, sunless tanning agents, viscosity modifiers and vitamins. As is known to one skilled in the art, in some instances a specific additional component may have more than one activity, function or effect.


In an embodiment of the present invention, the additional component is a pH adjusting agent or a buffering agent. Suitable buffering agents include but are not limited to acetic acid, adipic acid, calcium hydroxide, citric acid, glycine, hydrochloric acid, lactic acid, magnesium aluminometasilicates, phosphoric acid, sodium carbonate, sodium citrate, sodium hydroxide, sorbic acid, succinic acid, tartaric acid, and derivatives, salts and mixtures thereof.

Propellants


Examples of suitable propellants include volatile hydrocarbons such as butane, propane, isobutane and fluorocarbon gases, or mixtures thereof.


In certain embodiments, fluorohydrocarbon propellants, other than chloro-fluoro carbons (CMCs) which are non-ozone-depleting propellants, are particularly useful in the production of a non-flammable foamable composition.


Such propellants include, but are not limited to hydrofluorocarbon (HFC) propellants, that contain no chlorine atoms, and as such, falls completely outside concerns about stratospheric ozone destruction by chlorofluorocarbons or other chlorinated hydrocarbons. Exemplary non-flammable propellants according to this aspect of the invention include propellants made by DuPont under the registered trademark Dymel, such as 1,1,1,2 tetrafluorethane (Dymel 134), and 1,1,1,2,3,3,3 heptafluoropropane (Dymel 227), 1,1, difluoro ethane (Dymel 152) and 1,1,1,3,3,3 hexafluoropropane. HFCs possess Ozone Depletion Potential of 0.00 and thus, they are allowed for use as propellant in aerosol products.


The propellant makes up about 5-25 wt % of the foamable composition. Aerosol propellants are used to generate and administer the foamable composition as a foam. The total composition including propellant, foamable compositions and optional ingredients is referred to as the foamable composition.


Hygroscopic Property of the Composition


A hydroscopic substance is a substance that absorbs water readily from its surroundings. Microorganisms require water to grow and reproduce, and such water requirements are best defined in terms of water activity of the substrate. The water activity of a solution is expressed as Aw=P/Po, where P is the water vapor pressure of the solution and Po is the vapor pressure of pure water at the same temperature. Addition of a hygroscopic substance to an aqueous solution in which a microorganism is growing will have the effect of lowering the Aw, with a consequent effect upon cell growth. Every microorganism has a limiting Aw, below which it will not grow, e.g., for streptococci, klebsiella spp., escherichia coli, clostridium perfringens, and pseudomonas spp. the Aw value is 0.95. Staphylococcus aureus is most resistant and can proliferate with an Aw as low as 0.86.


The water activity of a product can be determined from the relative humidity of the air surrounding the sample when the air and the sample are at equilibrium. Measurement is performed by placing a sample in an enclosed space where this equilibrium can take place. Once this occurs, the water activity of the sample and the relative humidity of the air are equal. The measurement taken at equilibrium is called an equilibrium relative humidity or ERH. The relationship between the water activity and ERH is in accordance with the following formula:

Aw=ERH/100


Various types of water activity instruments are commercially available. One exemplary instrument uses chilled-mirror dewpoint technology while other instruments measure relative humidity with sensors that change electrical resistance or capacitance.


Polyols, PEGs and other polar solvents have a great affinity for water, and as such, they exhibit hygroscopic properties. The concentration of the polyol, the PEG and/or other polar solvents determines the Aw of the carrier. In one or more embodiments, the polyols, the PEG and/or the secondary polar solvent is contained in the composition of the present invention at a sufficient concentration to provide an Aw value of the hygroscopic carrier of less than 0.9. In other embodiments, the concentration of the polyol, the PEG and/or secondary polar solvent in the composition is selected to provide a Aw value selected from the ranges of (1) about 0.8 and about 0.9; (2) about 0.7 and about 0.8; and (3) less than about 0.7.


As such, a composition containing a polyol, a PEG with or without a secondary polar solvent can be used as topical treatment of superficial infectious conditions.


The advantage of providing a hygroscopic composition in a pressurized packaging presentation is readily perceived. The usage of all other presentations, such as solutions, creams, lotions, ointments and the like involves repeated opening of the package closure, resulting in absorption of water from the surrounding environment and a subsequent elevation of the Aw (thus lowering the hygroscopicity of the product, and therefore decreasing its anti-infective potential. By contrast, a pressurized packaging does not allow for any humidity to be absorbed by the preparation, and therefore, the hygroscopic character of the composition cannot be damaged.


In one or more embodiments, the hygroscopic composition of the present invention further contains an anti-infective agent, selected from the group of an antibiotic agent, an antibacterial agent, an antifungal agent, an agent that controls yeast, an antiviral agent and an antiparasitic agent. Combining the anti-infective effect of a hygroscopic composition, which acts through a dehydration mechanism, with an additional anti-infective agent that acts through alternate mechanisms results in a synergistic effect and consequently higher success rate of the treatment.


Composition and Foam Physical Characteristics and Advantages


A pharmaceutical or cosmetic composition manufactured using the foamable carrier of the present invention is very easy to use. When applied onto the afflicted body surface of mammals, i.e., humans or animals, it is in a foam state, allowing free application without spillage. Upon further application of a mechanical force, e.g., by rubbing the composition onto the body surface, it freely spreads on the surface and is rapidly absorbed.


The foamable composition of the present invention is stable, having an acceptable shelf-life of at least one year, or preferably, at least two years at ambient temperature, as revealed in accelerated stability tests. Organic carriers and propellants tend to impair the stability of emulsions and to interfere with the formation of stable foam upon release from a pressurized container. It has been observed, however, that the foamable compositions according to the present invention are surprisingly stable. Following accelerated stability studies, they demonstrate desirable texture; they form fine bubble structures that do not break immediately upon contact with a surface, spread easily on the treated area and absorb quickly.


The composition should also be free flowing, to allow it to flow through the aperture of the container, e.g., and aerosol container, and create an acceptable foam.


Foam quality can be graded as follows:


Grade E (excellent): very rich and creamy in appearance, does not show any bubble structure or shows a very fine (small) bubble structure; does not rapidly become dull; upon spreading on the skin, the foam retains the creaminess property and does not appear watery.


Grade G (good): rich and creamy in appearance, very small bubble size, “dulls” more rapidly than an excellent foam, retains creaminess upon spreading on the skin, and does not become watery.


Grade FG (fairly good): a moderate amount of creaminess noticeable, bubble structure is noticeable; upon spreading on the skin the product dulls rapidly and becomes somewhat lower in apparent viscosity.


Grade F (fair): very little creaminess noticeable, larger bubble structure than a “fairly good” foam, upon spreading on the skin it becomes thin in appearance and watery.


Grade P (poor): no creaminess noticeable, large bubble structure, and when spread on the skin it becomes very thin and watery in appearance.


Grade VP (very poor): dry foam, large very dull bubbles, difficult to spread on the skin.


Topically administrable foams are typically of quality grade E or G, when released from the aerosol container. Smaller bubbles are indicative of more stable foam, which does not collapse spontaneously immediately upon discharge from the container. The finer foam structure looks and feels smoother, thus increasing its usability and appeal.


As further aspect of the foam is breakability. The breakable foam is thermally stable, yet breaks under sheer force. Sheer-force breakability of the foam is clearly advantageous over thermally induced breakability. Thermally sensitive foams immediately collapse upon exposure to skin temperature and, therefore, cannot be applied on the hand and afterwards delivered to the afflicted area.


The foam of the present invention has several advantages, when compared with hydroalcoholic foam compositions, such as described in WO 2004/071479:

  • (1) Breakability. The foam of the present invention is thermally stable. Unlike hydroalcoholic foam compositions of the prior art, the foam of the present invention is not “quick breaking”, i.e., it does not readily collapse upon exposure to body temperature environment. Sheer-force breakability of the foam is clearly advantageous over thermally induced breakability, since it allows comfortable application and well directed administration to the target area.
  • (2) Skin drying and skin barrier function. Short chain alcohols are known to dry the skin and impair the integrity of the skin barrier. By contrast, including a film forming agent in the composition of the present invention foes not cause unwanted skin barrier damage.
  • (3) Irritability. Due to the lack of alcohol and improvement in skin barrier function, skin irritability is eliminated.


Another property of the foam is specific gravity, as measured upon release from the aerosol can. Typically, foams have specific gravity of less than 0.12 g/mL; or less than 0.10 g/mL; or less than 0.08 g/mL, depending on their composition and on the propellant concentration.


Pharmaceutical Composition


The foamable composition of the present invention is an ideal vehicle for active pharmaceutical ingredients and active cosmetic ingredients. In the context of the present invention, active pharmaceutical ingredients and active cosmetic ingredients are collectively termed “active agent” or “active agents”. A foamable composition, comprising an active agent has the following advantages:

    • 1. The foamable composition provides a preferred solvent for active agents, particularly water-insoluble agents.
    • 2. The inclusion of a polyol and/or a PEG and a secondary polar solvent in the foamable composition facilitates a co-solvent effect, resulting increased concentrations of soluble active agent in the dosage form, thus facilitating enhanced skin penetration of the active agent. In many cases, increased penetration is positively correlated with improved clinical outcome. In certain case, attaining an increased drug penetration into the target site of action enables a decrease of treatment frequency, for example, from twice or three times daily to once daily.
    • 3. Polyols and PEGs; and combinations of a polyol and/or PEG with a secondary polar solvent are known as skin penetration enhancers, thus, increasing drug residence in the target area and increasing clinical efficacy, as detailed above.
    • 4. The fact that the composition contains no water, or up to 25% and more preferably up to 10% water minimizes the probability of degradation of water-sensitive active agents. Furthermore, as exemplified herein, a foam containing a polyol and/or PEG with no water at all can be formed in accordance with the composition and process of the present invention. Such compositions ensure high stability of water sensitive active agents.
    • 5. Combining the anti-infective effect of a hygroscopic composition, which acts through a dehydration mechanism, with an additional anti-infective agent, selected from the group of an antibiotic agent, an antibacterial agent, an antifungal agent, an agent that controls yeast, an antiviral agent and an antiparasitic agent, that acts through alternate mechanisms results in a synergistic effect and consequently higher success rate of the treatment.
    • 6. The foamable polyol composition in contained in an impermeable pressurized packaging presentation is impermeable and thus, the active agent is not exposed to environmental degradation factors, such as light and oxidating agent during storage.


Thus, in a preferred embodiment of the present invention, the composition includes at least one active agent.

    • a. a therapeutically effective concentration of an active agent; and
    • b. about 50% to about 98% of a polar solvent, selected from the group consisting of a polyol and a polyethylene glycol;
    • c. 0% to about 48% of a secondary polar solvent;
    • d. about 0.2% to about 5% by weight of a surface-active agent;
    • e. about 0.01% to about 5% by weight of at least one polymeric agent; and
    • f. a liquefied or compressed gas propellant at a concentration of about 3% to about 25% by weight of the total composition.


In the context of combining a hygroscopic carrier according to the present invention and an anti-infective active agent, a pharmaceutical composition is provided, including:

    • a. a hygroscopic substance at a sufficient concentration to provide an Aw value of the hygroscopic carrier of less than 0.9. The concentration of the hygroscopic substance in the composition can be designed to provide a Aw value selected from the ranges of (1) about 0.8 and about 0.9; (2) about 0.7 and about 0.8; and (3) less than about 0.7;
    • b. about 0.2% to about 5% by weight of a surface-active agent;
    • c. about 0.01% to about 5% by weight of at least one polymeric agent selected from a bioadhesive agent, a gelling agent, a film forming agent and a phase change agent;
    • d. a therapeutically effective concentration of an anti-infective agent; and
    • e. a liquefied or compressed gas propellant at a concentration of about 3% to about 25% by weight of the total composition.


An exemplary case for the inclusion of an anti-infective agent in a hygroscopic composition is provided herewith. It has been surprisingly discovered that combining an antifungal agent in a hygroscopic composition results in an anti-infective effect on strains that are not supposed to be affected by the said antifungal agent. For example, terbinafine is know to be highly effective against dermatophite pathogens, but not against candida. In-vitro studies have revealed, however that terbinafine, dissolved in a hygroscopic carrier, effectively inhibited the spreading of candida albicans, while a control preparation, comprising the same concentration of terbinafine in an emulsion base was not effective. Thus, combining an antifungal agent in a hygroscopic composition results in an expansion of the spectrum of infective strains that can benefit form the therapy, and furthermore, in can render an improved effect of such a composition on mixed infections or in infections that are not accurately diagnosed.


Consequently, in another aspect of the present invention, a pharmaceutical composition, which possesses an improved antifungal activity or that possesses an antifungal activity on an expanded spectrum of pathogens, is provided, including:

    • a. a hygroscopic composition, comprising a hygroscopic substance at a sufficient concentration to provide an Aw value of the hygroscopic carrier of less than 0.9. The concentration of the hygroscopic substance in the composition can be designed to provide a Aw value selected from the ranges of (1) about 0.8 and about 0.9; (2) about 0.7 and about 0.8; and (3) less than about 0.7;
    • b. an anti-infective agent, selected from the group of an antibiotic agent, an antibacterial agent, an antifungal agent, an agent that controls yeast, an antiviral agent and an antiparasitic agent. Preferably, the anti-infective agent is an antifungal agent, and more preferably the anti-infective agent is terbinafine.

Several disorders of the skin, body cavity or mucosal surface (e.g., the mucosa or the cavity of the nose, mouth, eye, ear, vagina or rectum) involve a combination of etiological factors. For example, fungal and bacterial infections and that are inflamed and have symptoms of redness and/or itching warrant therapy that combines an anti-infective agent and an anti-inflammatory agent. Thus, in several cases, combining at least two active agents that treat different etiological factors results in a synergistic effect and consequently higher success rate of the treatment.


In certain cases, the composition contains two active agents, where each of the active agents require a different pH environment in order to remain stable. For example, corticosteroids are typically stable at acidic pH values (they have a maximum stability at a pH of about 4-6) and of vitamin D analogues are typically stable at basic pH values (they have a maximum stability at pH values above about 8). In order to circumvent the problem of instability it is preferred that the composition is substantially non-aqueous. The term “substantially non-aqueous” is intended to indicate that the composition has a water content below about 5%, preferably below about 2%, such as below about 1.5%.


Fields of Applications


The foamable carrier of the present invention is suitable for treating any infected surface. In one or more embodiments, foamable carrier is suitable for administration to the skin, a body surface, a body cavity or mucosal surface, e.g., the cavity and/or the mucosa of the nose, mouth, eye, ear, respiratory system, vagina or rectum (severally and interchangeably termed herein “target site”).


By selecting a suitable active agent, or a combination of at least two active agents, the foamable composition of the present invention is useful in treating an animal or a human patient having any one of a variety of dermatological disorders, including dermatological pain, dermatological inflammation, acne, acne vulgaris, inflammatory acne, non-inflammatory acne, acne fulminans, nodular papulopustular acne, acne conglobata, dermatitis, bacterial skin infections, fungal skin infections, viral skin infections, parasitic skin infections, skin neoplasia, skin neoplasms, pruritis, cellulitis, acute lymphangitis, lymphadenitis, erysipelas, cutaneous abscesses, necrotizing subcutaneous infections, scalded skin syndrome, folliculitis, furuncles, hidradenitis suppurativa, carbuncles, paronychial infections, rashes, erythrasma, impetigo, ecthyma, yeast skin infections, warts, molluscum contagiosum, trauma or injury to the skin, post-operative or post-surgical skin conditions, scabies, pediculosis, creeping eruption, eczemas, psoriasis, pityriasis rosea, lichen planus, pityriasis rubra pilaris, edematous, erythema multiforme, erythema nodosum, grannuloma annulare, epidermal necrolysis, sunburn, photosensitivity, pemphigus, bullous pemphigoid, dermatitis herpetiformis, keratosis pilaris, callouses, corns, ichthyosis, skin ulcers, ischemic necrosis, miliaria, hyperhidrosis, moles, Kaposi's sarcoma, melanoma, malignant melanoma, basal cell carcinoma, squamous cell carcinoma, poison ivy, poison oak, contact dermatitis, atopic dermatitis, rosacea, purpura, moniliasis, candidiasis, baldness, alopecia, Behcet's syndrome, cholesteatoma, Dercum disease, ectodermal dysplasia, gustatory sweating, nail patella syndrome, lupus, hives, hair loss, Hailey-Hailey disease, chemical or thermal skin burns, scleroderma, aging skin, wrinkles, sun spots, necrotizing fasciitis, necrotizing myositis, gangrene, scarring, and vitiligo.


Likewise, the foamable composition of the present invention is suitable for treating a disorder of a body cavity or mucosal surface, e.g., the mucosa of the nose, mouth, eye, ear, respiratory system, vagina or rectum. Non limiting examples of such conditions include chlamydia infection, gonorrhea infection, hepatitis B, herpes, HIV/AIDS, human papillomavirus (HPV), genital warts, bacterial vaginosis, candidiasis, chancroid, granuloma Inguinale, lymphogranloma venereum, mucopurulent cervicitis (MPC), molluscum contagiosum, nongonococcal urethritis (NGU), trichomoniasis, vulvar disorders, vulvodynia, vulvar pain, yeast infection, vulvar dystrophy, vulvar intraepithelial neoplasia (VIN), contact dermatitis, pelvic inflammation, endometritis, salpingitis, oophoritis, genital cancer, cancer of the cervix, cancer of the vulva, cancer of the vagina, vaginal dryness, dyspareunia, anal and rectal disease, anal abscess/fistula, anal cancer, anal fissure, anal warts, Crohn's disease, hemorrhoids, anal itch, pruritus ani, fecal incontinence, constipation, polyps of the colon and rectum.


In an embodiment of the present invention, the composition is useful for the treatment of an infection. In one or more embodiments, the composition is suitable for the treatment of an infectiion, selected from the group of a bacterial infection, a fungal infection, a yeast infection, a viral infection and a parasitic infection.


In an embodiment of the present invention, the composition is useful for the treatment of wound, ulcer and burn. This use is particularly important since the composition of the present invention creates a thin, semi-occlusive layer, which coats the damaged tissue, while allowing exudates to be released from the tissue.


The composition of the present invention is also suitable for administering a hormone to the skin or to a mucosal membrane or to a body cavity, in order to deliver the hormone into the tissue of the target organ, in any disorder that responds to treatment with a hormone.


In light of the hygroscopic nature of the composition, it is further suitable for the treatment and prevention of post-surgical adhesions. Adhesions are scars that form abnormal connections between tissue surfaces. Post-surgical adhesion formation is a natural consequence of surgery, resulting when tissue repairs itself following incision, cauterization, suturing, or other means of trauma. When comprising appropriate protective agents, the foam is suitable for the treatment or prevention of post surgical adhesions. The use of foam is particularly advantageous because foam can expand in the body cavity and penetrate into hidden areas that cannot be reached by any other alternative means of administration.


The invention is described with reference to the following examples. This invention is not limited to these examples and experiments. Many variations will suggest themselves and are within the full intended scope of the appended claims.

Comparative In-Vitro Activity of a Hygroscopic Composition Containing Terbinafine

A comparative in-vitro study was set to evaluate the effect of Composition A, consisting of 2% terbinafine, 95.3% gr. polyethylene glycol, 0.5% hydroxypropyl cellulose and 2.2% steareth-2, in comparison with Composition B (an oil in water emulsion containing 2% terbinafine) and Composition C a commercial 1% bifonazole cream.


Three fungal strains (microsporum canis, trichophyton mentagrophytes and trichophyton rubrum) and one yeast (candida albicans) were seeded in the center of a Petri dish, and then, were surrounded by a film containing each of the compositions, using a swab, soaked with each of the compositions. The proliferation and spreading of the microorganisms was followed up for 14 day by visual and photographic observations.


As shown in FIG. 1, Composition A inhibited the proliferation and spreading of all the fungal and yeast strains effectively. By contrast, both Compositions B and C failed to inhibit the growth of candida. Composition C was also ineffective in the inhibition of microsporum canis and Trichophyton rubrum.

Example 14
Comparison between Polyethylene-Based Foamable Compositions with and without Gelling Agent

The compositions of the test articles are provided in the following table. All foams were dispensed on a warm surface (38° C.), and the time to full collapse of the foam was measured. As shown in the table, it has been strikingly demonstrated that foam compositions without a gelling agent exhibit a 100% breakdown within 30 seconds, while foams containing gelling agent remained, with and without surfactant, were stable for several minutes. This is relevant from the usability point of view, since a foam that is unstable at skin temperature cannot be applied to large areas affectively.
