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.

Description

technical field [0001] The invention belongs to the field of veterinary medicine, in particular to a compound florfenicol and neomycin sulfate nano-emulsion preparation and a preparation method thereof. Background technique [0002] Both florfenicol and neomycin sulfate are antibacterial drugs widely used clinically. They have the characteristics of broad antibacterial spectrum, strong bactericidal power and rapid action. They are widely used to treat sensitive animals such as respiratory system, urogenital system, skin and soft tissue. bacterial infection. However, due to long-term and extensive use, many pathogenic bacteria have developed certain resistance to these two drugs. In CN102068443A, florfenicol and neomycin sulfate are used in combination to prepare an ultrafine powder to enhance the curative effect, reduce the dosage, and have better curative effect on aquatic bacterial diseases. However, the powder in the prior art needs to be mixed with drinking water and t...
