Sodium sulfamonomethoxine injection and preparation method and system thereof

Abstract

The invention provides a sodium sulfamonomethoxine injection and a preparation method and system thereof. The preparation method comprises the following steps: mixing sodium sulfamonomethoxine, a stabilizer, sodium thiosulfate, disodium ethylenediamine tetraacetate and water to obtain a first solution, a second solution and a third solution, mixing the first solution, the second solution and the third solution to obtain a mixed solution, mixing the mixed solution and water so that the volume reaches a predetermined volume, adjusting the pH value of the mixed solution, filtering the solution and mixing the filtered mixed solution and water to obtain the sodium sulfamonomethoxine injection. The injection comprises the solution prepared by the method. The preparation system comprises an injection water unit, a pH adjusting unit, a liquid preparation unit, a mixing unit, a first filtering unit, a volume adjusting unit, a second filtering unit and a liquid storage unit which are arranged insequence. The preparation method is simple and convenient, the injection stability is good, the solution color is not easily influenced by the environment, the treatment effect is good, and the product preparation efficiency is high.

Description

technical field [0001] The invention relates to the field of veterinary drugs, in particular to a sulfamethoxine sodium injection, a preparation method and a preparation system thereof. Background technique [0002] Sulfamethoxine sodium is a sulfonamide synthetic antibacterial drug, which has a strong inhibitory effect on most Gram-positive bacteria and negative bacteria, and has the advantages of not being easy to deteriorate and easy to use. Sulfamethoxine sodium can be mainly used for respiratory tract, digestive tract, urinary tract infection, coccidiosis and swine toxoplasmosis caused by sensitive bacteria. At present, there are still some defects in the sulfamethoxine sodium injection, such as unstable properties, such as easy discoloration, easy crystallization and the like. Contents of the invention [0003] In view of the deficiencies in the prior art, the purpose of the present invention is to solve one or more problems in the above prior art. For example, one...
