Abstract

The invention belongs to the field of veterinary medicine, and in particular relates to a compound florfenicol and neomycin sulfate nanoemulsion formulation with high stability and a good absorption effect and a preparation method thereof. The nanoemulsion formulation is of oil-in-water type with a particle size of 1-100 nm, and is prepared from florfenicol, neomycin sulfate, a cosolvent, a surfactant, a cosurfactant, oil and distilled water. The invention is simple in preparation process, low in production cost, good in drug absorption effect, and improved in drug utilization; the method uses nanoemulsion as a drug carrier; and the formulation has the advantages of broad spectrum, efficiency, target, sustained release, security, etc. and is significant in the effect of treatment of bacterial infection.
