Definitions
- the present disclosure relates to a pharmaceutical composition for the prevention or treatment of tinea versicolor and skin dermatitis.
- Tinea is a general term for superficial mycoses caused by dermatophytes. Dermatophytes are keratinophilic fungi that parasitize the keratin of the stratum corneum of the epidermis, hair, fingernails, and toenails, and have keratinase that can dissolve keratin.
- tinea versicolor is classified into tinea captis, tinea coporis, tinea cruris, tinea barbae, tinea faciel, tinea manus, tinea pedis, and tinea unguium depending on the site of occurrence [Byung Ho Oh, Kyu Joong Ahan. "Drug Therapy of Dermatophytosis” J Korean Med. Assoc. 2009, 52(11):1109-1114].
- the causative agent of tinea versicolor may vary depending on the site of occurrence and the patient's age, but common causative agents include Trichophyton rubrum, Trichophyton mentagrophytes, Epidermophyt floccosum, Microsporum canis, the yeast Candida albicans, and the fungus Aspergillus niger.
- Trichophyton rubrum accounts for 60% and Trichophyton mentagrophytes accounts for 20%.
- onychomycosis occurs frequently in people over 40 years of age, and as the causative agents of tinea onychomycosis, Trichophyton rubrum accounts for 91.0% and Trichophyton mentagrophytes accounts for 7.7% [Uwe Wollina, Holger Haenssle, Dtsch Cardioebl Int. 2016;113(29-30):509-518].
- onychomycosis can be classified into 1 distal and lateral subungal onychomycosis (DLSO), 2 proxmimal subungal onychomycosis (PSO), 3 white superficial onychomycosis (WSO), 4 endonyx onychomycosis (EO), and 5 total dystrophic onychomycosis (TDO).
- DLSO distal and lateral subungal onychomycosis
- PSO proxmimal subungal onychomycosis
- WSO white superficial onychomycosis
- EO endonyx onychomycosis
- TDO total dystrophic onychomycosis
- antifungal agents are largely classified into polyenes, azoles, allylamines, benzylamines, morpholines, hydroxypyridones, and oxaboroles.
- luriconazole 1% cream/5% solution
- efinaconazole 10% solution
- terbinafine 1% cream/spray
- amorolfine 5% nail lacquer
- ciclopirox 8% nail lacquer
- tavaborole 5% solution
- Jubulia Esinaconazole 10%
- Luconac Liconazole 5%
- Kerydin Teavabole 5%
- methylpyrrolidone is classified as a carcinogen, mutagenic, or reproductive toxic substance, and its use is strictly regulated as a hazardous substance.
- ethylenediamine tetraacetic acid salt which has been used as a chelating agent for a long time, has poor biodegradability, and there is concern that it may deposit heavy metals in soil and water and cause heavy metals to enter the food chain, so it is not desirable to use it in terms of environmental friendliness.
