Abstract

A kitasamycin antimicrobial nanoemulsion drug and a preparation method thereof. The kitasamycin antimicrobial nanoemulsion drug is a composition having a particle size range of between 1nm to 100nm and comprising 0.1%-5% by weight of kitasamycin, 0.1%-8% by weight of an oil phase, 25%-40% by weight of a surfactant, and 4%-25% by weight of a cosurfactant, and the balance water. Combining the composition with the preparation method, the kitasamycin antimicrobial nanoemulsion drug with high bioavailability, low toxic and side effects, good stability, and good palatability is obtained.

Description

technical field [0001] The invention belongs to the field of veterinary medicine, and relates to a new dosage form of nano-medicine, in particular to a kitasarmycin nano-emulsion antibacterial drug and a preparation method thereof, in particular to a clear and transparent kitasarmycin nano-emulsion anti-bacterial drug and a preparation method thereof. Background technique [0002] Nanoemulsion is composed of oil phase, water phase, surfactant and co-surfactant mixed in appropriate proportions. The appearance should be a transparent or translucent liquid. Nanoemulsion is a low-viscosity, kinetically and thermodynamically stable system, the particle size should be between 1nm and 100nm. [0003] Kitamycin, also known as column crystal leucomycin, beilimycin, is a multi-component macrolide antibiotic produced by Streptomyces, which is white or light yellow powder, and can be dissolved in methanol, ethanol, chloroform, ether Easily soluble in water, almost insoluble in water. ...
