Tilmicosin solution and preparation method thereof

Abstract

The invention relates to a tilmicosin solution, mainly comprising injection water, tilmicosin and sodium bisulfite; 100ml of injection water contains 7.5-20g of tilmicosin and 0.05-0.2g of sodium bisulfite. The invention further relates to a preparation method of the tilmicosin solution, comprising partially weighing the injection water, regulating pH value, adding the tilmicosin, then adding the sodium bisulfite, supplying the injection water, adding active carbon, decarbonization and filtration. The invention solves the problem that tilmicosin phosphate is required to prepare the tilmicosin solution in the prior art and makes up for the shortage of the prior art.

Description

technical field [0001] The invention relates to a tilmicosin solution and a preparation method thereof. Background technique [0002] Porcine respiratory disease syndrome is also called "multifactor porcine respiratory disease", "porcine complex pneumonia", and "porcine respiratory complex infection". The disease is a highly contagious infectious disease that can spread rapidly through the air, mainly through respiratory tract infection, and can also spread through the placenta. The main features of the disease are: different clinical symptoms, long course of disease and long course of treatment, which can be controlled only by combination of drugs. The disease occurs more frequently in the cold season, and the breeding conditions are poor, the pens are humid, crowded and poorly ventilated, or parasitic diseases are most likely to be caused. [0003] The pathogenic causes of porcine respiratory syndrome are quite complicated, and it is a multifactor complex disease. It is...
