Problems solved by technology

For the unilateral cream with relatively good curative effect, due to the special administration method of cream and other external preparations, it is impossible to combine two external preparations for treatment at the same time, and the combination ratio of the two has not been scientifically verified. It is also difficult to achieve the best synergistic or cumulative effect with a suitable ratio. For example, although terbinafine hydrochloride ointment and sertaconazole nitrate ointment have been reported in combination to treat tinea pedis, one (sertaconazole nitrate ointment) morn

Embodiment 1

[0082] Prepare the antifungal composition ointment for external use according to the following formula (prepared by 10 grams, the following is in g):

[0083]

[0084] The preparation method is as follows:

[0085] Dissolve terbinafine hydrochloride and sertaconazole in propylene glycol for later use; then add sodium lauryl sulfate, glycerin, methyl Nepal, and propyl Nepal into purified water with stirring, and heat to 80-85°C (water phase ); cetearyl alcohol, white petrolatum, liquid paraffin, glyceryl monostearate, and stearic acid are heated to 80-85°C (oil phase); the water phase is added to the oil phase to form a cream, and the drug solution is added to continue emulsification , and stirring constantly, slowly cooled to room temperature.

Abstract

The invention provides an antifungal drug composition for external use, and a preparation method of an external preparation, and application of the composition in treating superficial fungal infections, such as tinea manus and pedis, tinea corporis, tinea cruris, tinea unguium, tinea versicolor and oidiomycosis cutis. The drug composition contains terbinafine or pharmaceutical salt thereof, sertaconazole or pharmaceutical salt thereof, and any one or multiple pharmaceutically acceptable excipient. An experimental study shows that the terbinafine or pharmaceutical salt thereof and the sertaconazole or pharmaceutical salt thereof have obvious synergistic effect when the proportion thereof in the drug composition for treating the superficial fungal infections is (1: 10) to (5: 1)(w/w). The antifungal drug composition for treating the superficial fungal infections has the advantages of being good in security, excellent in curative effect, short in treatment course, high in curing rate, low in relapse rate and the like.

Description

technical field [0001] The present invention relates to topical compositions for the treatment of superficial fungal infections. More specifically, the present invention relates to an antifungal composition for external use comprising terbinafine or a pharmaceutically acceptable salt thereof and sertaconazole or a pharmaceutically acceptable salt thereof. Background technique [0002] Superficial fungal infection is an infection caused by pathogenic fungi invading the stratum corneum, hair, and nail plate of the skin. The main pathogen is dermatophyte, and other common pathogens include Malassezia and Candida. Superficial mycoses caused by superficial fungal infections include tinea capitis, tinea corporis, tinea manuum, onychomycosis, tinea versicolor and Malassezia folliculitis, etc. A fungal disease with a high rate. In recent years, due to obesity, the abuse of topical glucocorticoids, the increase in the incidence of diabetes, the increase in the frequency of people ...
