Definitions
- the present invention relates to an antifungal composition
- an antifungal composition comprising an arylamine antifungal agent, a fatty acid ester, a powder component, an alcoholic solvent, and an antipruritic component.
- the present invention relates to a composition having an excellent therapeutic effect on sexual mycosis (eg, tinea pedis, tinea corporis, tinea cruris, etc.).
- fungi In superficial mycosis, fungi mainly penetrate into the stratum corneum of the skin and proliferate. Therefore, a condition for an antifungal agent to exhibit excellent medicinal effects against superficial mycosis is that the drug itself must be used. It is necessary that the body has strong antifungal activity and high affinity for the site of infection.
- superficial mycosis can be broadly divided into symptoms in which the affected area is relatively dry and symptoms in which the affected area is wet, and a formulation suitable for the condition of the affected area is needed.
- an arylamine antifungal agent having excellent antifungal activity and keratophilicity satisfying such conditions has been put to practical use.
- terbinafine and its salts As the antifungal agent, terbinafine and its salts, terbinafine hydrochloride and naphthytin, are known to have excellent effects when used alone. Therefore, there is a demand for the development of antifungal agents that can achieve a high therapeutic effect that is more tailored to the symptoms and that can improve the patient's QOL (life comfort).
- Patent Document 1 a dry spray-type antifungal composition containing an acyclic silicone polymer, an inorganic or organic filler, and a propellant in the arylamine-based antifungal agent.
- Patent Document 1 states that by adding an acyclic silicone polymer to an antifungal-containing dry spray used for wet athlete's foot, an even amount of active ingredient can be obtained even when intermittent spraying is performed.
- an acyclic silicone polymer to an antifungal-containing dry spray used for wet athlete's foot, an even amount of active ingredient can be obtained even when intermittent spraying is performed.
