"TOPICAL PHARMACEUTICAL COMPOSITION COMPRISING MICONAZOLE AND LULICONAZOLE OR SALTS THEREOF"
FIELD OF THE INVENTION
The present invention relates to topical pharmaceutical composition comprising Miconazole and Luliconzole or salts thereof in the treatment of fungal infection.
BACKGROUND OF THE INVENTION
An antifungal agent is a drug that selectively eliminates fungal pathogens from a host with minimal toxicity to the host. Topical antifungals are products that treat fungal infections and which are applied directly to the skin, nails, or hair; vaginally; or inside the mouth. Fungal infections are caused by dermatophytes, yeasts, and molds. There are about 40 different species of dermatophyte, and they obtain their nutrients from keratinized material, so typically are the organisms responsible for fungal infections of the skin, scalp or nails. Yeasts are normal inhabitants of our skin but sometimes they grow unheeded which can result in symptomatic infections. Molds are an uncommon cause of fungal infections but they can cause tinea nigra (painless brown or black patches on the skin) or hard-to-treat nail infections.
Like antibiotics, antifungal agents are classified into different categories. Azole and imidazole antifungal agents include Luliconzole, Miconazole, Clotrimazole (mainly topical application), Ketoconazole, Butoconazole, Oxiconazole and Econazole. Triazoles include Itraconazole, Fluconazole, Voriconazole and Posaconazole. Echinocandins include Caspofungin, Micafungin and Anidulafungin. Antimetabolites include Flucytosine. Allylamines like Terbinafine, Naftifine, and Butenafine. Miscellaneous antifungals include Ciclopirox olamine, Haloprogin, Undecylenic acid, Benzoic acid and Salicylic acid.

Miconazole nitrate is a synthetic antifungal agent. Chemically Miconazole nitrate is l-[2, 4-dichloro-β-{(2,4-dichlorobenzyl)oxy} phenethyl] imidazole mononitrate and its molecular weight is of 479.15. Its empirical formula is C18H14CI4N2OHNO3. Miconazole nitrate is represented by compound of structural formula I

Miconazole nitrate is a white to almost white powder. It is soluble in water and organic solvents such as ethanol, dimethyl sulfoxide (DMSO) and dimethyl formamide (DMF), propylene glycol or pyridine.
Miconazole nitrate topical cream (2%) was approved in USA prior to Jan 1, 1982 under the trade name "Monistat-Derm" and was indicated for the treatment of tinea pedis (athlete's foot), tinea cruris and tinea corporis caused by Trichophyton rubrum, Trichophyton mentagrophytes, and Epidermophyton floccosum, in the treatment of cutaneous candidiasis (moniliasis) and in the treatment of tinea versicolor.
Luliconazole is an azole antifungal agent. Chemically Luliconazole is (2E)-2-[(4R)-4-(2,4-dichlorophenyl)-l,3-dithiolan-2-ylidene]-2-imidazol-l-ylacetonitrile and its molecular weight is of 354.28. Its empirical formula is C14H9CI2N3S2. Luliconazole is the R enantiomer and contains one chiral center. The double bond adjacent to the dithiolane group is in the E configuration. Luliconazole is represented by compound of structural formula II.


Luliconazole drug substance is a pale to light yellow crystalline powder. It is low soluble in water and soluble in acetonitrile, dimethyl sulfoxide and methanol.
Luliconazole topical cream (1%) was approved in USA on Nov 14, 2013 under the trade name "Luzu" and is indicated for the treatment of interdigital tinea pedis, tinea cruris and tinea corporis caused by the organisms Trichophyton rubrum and Epidermophyton floccosum, in patients 18 years of age and older.
US 20160243147 discloses topical paste comprising one or more antifungal agents along with an inert powder and pharmaceutically acceptable topical carrier. It generically discloses antifungal agent such as clotrimazole, ketoconazole, miconazole, oxiconazole, econazole, luliconazole, terbinafine, nystatin, fluconazole, voriconazole, itraconazole, caspofungin, micafungin, naftifine, butenafine, amorolfinc, ravuconazole, posaconazole, flucytosine, sertaconazole, efinaconazole, enilaconazole, saperconazole, sulconazole, terconazole, tioconazole, nikkomycin Z, anidulafungin (LY303366), pimaricin, griseofulvin, haloprogin, tolnaftate, undecylenate or any combination thereof. Further, this patent application specifically discloses nystatin containing antifungal composition.

DETAIL DESCRIPTION OF THE INVENTION
The present invention relates to a topical pharmaceutical composition comprising Miconazole or salts thereof and Luliconazole or salts thereof.
The salts of Miconazole are selected from from nitrate, maleate, hemifumarate, and hemisuccinate and the like. The preferred salt of miconazole is nitrate.
Similarly the salts of Luliconazole are selected from formic acid, acetic acid, citric acid, tartaric acid, bitartaric acid, benzoic acid, lactic acid, malic acid, fumaric acid, succinic acid, gluconic acid, pamoic acid, methanesulfonic acid, benzenesulfonic acid, hydrochloric acid, hydrobromic acid, hydroiodic acid, nitric acid, phosphoric acid, sulfuric acid, trifluoroacetic acid and the like. In a preferred embodiment luliconazole is used in its base form.
The present topical composition comprising Miconazole or salts thereof and Luliconazole or salts thereof are effective in the treatment of fungal infections. Fungal infection includes any infection associated with fungi. In the present context, fungal infection particularly includes tinea pedis (athlete's foot), tinea

cruris, tinea corporis, cutaneous candidiasis (moniliasis), tinea versicolor, jock itch, or ringworm, skin infections caused by dermatophytes or yeasts and other.
Spectrum of antifungal activity of Miconazole nitrate includes many fungi, including yeasts and dermatophytes. It is particularly active against Candida spp. (C. guilliermondii and C. tropicalis), Trichophyton spp. {Trichophyton mentagrophytes and Trichophyton rubrum), Epidermophyton spp. (E. floccosum), Microsporum spp. (M canis), Pityrosporon orbiculare {Malassezia furfur) and other, but also possesses some activity against Gram-positive bacteria {Staphylococcus aureus).
Spectrum of antifungal activity of Luliconazole includes dermatophytes, yeasts, and some other fungi. It is particularly active against Trichophyton spp. {T. rubrum, T. mentagrophytes, T. tonsurans, T. verrucosum, T. violaceum, Microsporum canis and M. gypseum, Epidermophyton floccosum), Candida albicans, Malassezia furfur, Malassezia restricta, Malassezia slooffiae, and Malassezia sympodialis and other.
The present invention provides a novel topical pharmaceutical composition effectively treats fungal infections; wherein Miconazole acts by inhibiting the 14a-demethylation of lanosterol, which consequently leads to the inhibition of ergosterol synthesis in fungal cell membranes. Additionally, miconazole has been shown to induce reactive oxygen species in fungal biofilms, demonstrating a MIC value of >256µM against Candida species; Luliconazole acts by inhibiting the ergosterol synthesis by inhibiting the enzyme lanosterol demethylase. Inhibition of this enzyme's activity by azoles results in decreased amounts of ergosterol, a constituent of fungal cell membranes, and a corresponding accumulation of lanosterol.
The topical pharmaceutical composition can be prepared using routine skills and techniques known in the art.
