Abstract

The invention belongs to the technical field of veterinary preparations, and particularly relates to a sarafloxacin hydrochloride solution as well as a preparation method and application thereof. The sarafloxacin hydrochloride solution comprises the following components of, sarafloxacin hydrochloride, ethanolamine, a stabilizer, dimethyl sulfoxide, water and ethanol. According to the sarafloxacin hydrochloride solution, through the interaction of the ethanolamine, the dimethyl sulfoxide and the stabilizer, the sarafloxacin hydrochloride solution can still keep better stability after being placed in a high-temperature and high-humidity environment for 6 months, can be arbitrarily diluted with water according to a dilution ratio of 1:1 to 1:1000, keeps a non-discoloring, clear and transparent state, and shows better solubility. The sarafloxacin hydrochloride solution provided by the invention also has the advantages of simple preparation process, easy realization of industrial production and the like.

Description

technical field [0001] The invention belongs to the technical field of veterinary drug preparations, and in particular relates to a sarafloxacin hydrochloride solution and a preparation method and application thereof. Background technique [0002] Sarafloxacin hydrochloride is a third-generation fluoroquinolone broad-spectrum antibacterial drug specially used for animals. It has strong antibacterial activity and has antibacterial effects on Gram-negative bacteria, Gram-positive bacteria and mycoplasma, especially Escherichia coli , Salmonella, Klebsiella, Proteus, Pasteurella multocida, Campylobacter and other enterobacteria have shown good antibacterial properties, and are currently mainly used for livestock and poultry digestive system, respiratory system, and urinary tract infections caused by sensitive bacteria and treatment of mycoplasmosis. [0003] Sarafloxacin hydrochloride is almost slightly soluble in water and ethanol, and only 0.1g of sarafloxacin hydrochloride ...
