Abstract

The invention discloses a high-concentration compound florfenicol injection, and a preparation method and an application thereof. The method comprises the following steps: dissolving prescription doses of florfenicol and flunixin meglumine in a 75% single solvent, and carrying out heating stirring for dissolving; adding the solvent to a full capacity; adding 0.4% activated carbon, and adsorbing for 30min; and filtering, encapsulating, and carrying out 100DEG C flowing steam sterilization for 30minin order to obtain the high-concentration compound florfenicol injection. The compound florfenicol injection prepared through the preparation method has the advantages of safety, convenience, controllable quality, stable preparation process, suitableness for industrial production, and low cost; and the injection enhances the prevention effect on porcine and bovine infectious diseases caused by pathogenic microorganisms sensitive to florfenicol, improves the survival rate of pigs or cattle, and is suitable for popularization and application.

Description

[0001] technical field [0002] The invention relates to the field of medicine preparation, in particular to a high-concentration compound florfenicol injection and its preparation method and application. Background technique [0003] With the improvement of the intensive degree of livestock and poultry breeding industry and the gradual increase of breeding density, respiratory infectious diseases caused by pathogenic microorganisms have become an important class of diseases that affect the healthy development of pig and cattle breeding. Pasteurella multocida, Pasteurella hemolyticus, Actinobacillus pleuropneumoniae, Streptococcus pneumoniae, Bordetella bronchiseptica, Haemophilus parasuis and mycoplasma, etc.; with respiratory syndrome as the main symptom, the sick animals are depressed, loss of appetite, fever, dyspnea, panting, coughing, sneezing, mucus or purulent secretions in the nostrils, caused by The direct and indirect economic losses are huge. The principle of...
