Abstract

The invention discloses triamcinolone acetonide and miconazole emulsion type gel. The gel comprises econazole nitrate and triamcinolone with effective doses, as well as 1 to 9 weight percent of lipophilic phase and 90 to 98 weight percent of hydrophilic phase, wherein the lipophilic phase comprises a lipophilic compound and/or a lipophilic surfactant, and the hydrophilic phase comprises hydrophilic gel matrix, a hydrophilic compound and a hydrophilic surfactant. According to the triamcinolone acetonide and miconazole emulsion type gel prepared by the prescription disclosed by the invention, econazole nitrate and triamcinolone have good in stability and cannot be easily separated out, and the product has a good transparent appearance; due to the low content of lipophilic phase in the product, oily feeling does not exist after the gel is applied to skin; and the hydrophilic gel matrix is contained in the product, so that a transparent film can be formed after the gel is applied to skin, the texture is uniform and smooth, and the gel is easily applied, is not irritant and can be used for increasing the compliance of a patient.

Description

technical field [0001] The invention belongs to the field of medicine and relates to triamcinolone acetonide and econazole emulsion gel. Background technique [0002] Superficial fungal infections mostly occur on the body surface, mainly invading the skin, hair, and nails, etc., causing tinea pedis, tinea corporis, jock itch, tinea imbricate, onychomycosis, tinea capitis, and candidiasis of the skin. It has the characteristics of high morbidity, easy infection, easy recurrence or reinfection, etc., which brings harm and pain to patients no matter in terms of body or appearance. At present, triamcinolone acetonide econazole cream is a commonly used preparation and is widely used in the treatment of skin diseases. Econazole nitrate is a broad-spectrum antifungal drug, the chemical name is 1-[2,4-dichloro-β(4-chlorobenzyloxy)phenethyl]imidazole nitrate, and the molecular formula is C 18 h 15 Cl 3 N 2 O HNO 3 , with a relative molecular mass of 444.70, is white or yellowis...
