Problems solved by technology

[0003] Itraconazole is currently clinically mainly administered orally or intravenously, but the disadvantage is that it has certain liver toxicity. We have changed itraconazole from intravenous or oral administration to topical administration. The key is to use itraconazole The original systemic administration of conazole was changed to local topical administration, using the skin tissue as a penetration barrier to limit the absorption of itraconazole in the human body, avoiding the hepatotoxicity of itraconazole in the human body's metabolism process, and improving patient compliance
[0004] At present, there are also patents that provide the technology of itraconazole cream, but it is directly prepared by using insoluble itraconazole solid, which has the characteristics of being difficult to absorb, having low skin penetration, and allowing itraconazole to penetrate through the skin. The disadvantage of low absorption rate

Abstract

The invention provides a nanometer itraconazole external preparation and a preparation method and a use thereof, and the nanometer itraconazole external preparation comprises components of nanometer itraconazole and a matrix, wherein the matrix is selected from the multiple components of octodecyl alcohol, cetyl alcohol, stearic acid, isostearic acid, glyceryl monostearate, white vaseline, sodium lauryl sulfate, glycerin, liquid paraffin, solid paraffin, tween-80, tween-60, span-60, span-80, polyethylene glycol 4000, polyethylene glycol 400, polyethylene glycol 200, carbomer, propylene glycol, ethanol, benzyl alcohol, triethanolamine, carboxylation methyl cellulose, EDTA (ethylenediamine tetraacetic acid) or methyl hydroxybenzoate, and the content of the nanometer itraconazole is 0.1% by weight-10% by weight. By adopting the nanometer itraconazole external preparation, the shortcomings that the itraconazole is difficult to absorb in the external preparation, the skin penetration is not high and the percutaneous absorption rate of the itraconazole is not high are solved, the hepatotoxicity of the itraconazole during metabolism process of a human body is avoided, the bioavailability is improved, and a new administration way is provided for a patient.

Description

field of invention [0001] The invention relates to the technical field of medicine, in particular to a nano-scale itraconazole external preparation, its preparation method and its application. Background technique [0002] Itraconazole is a second-generation triazole synthetic antifungal drug with a broad antibacterial spectrum.
