Abstract

The invention relates to a salinomycin granule preparation preparation technology based on improvement of the spraying effect. The preparation technology includes the following steps that acidic fermentation liquid is prepared, wherein the pH of salinomycin fermentation liquid is adjusted to 4.0-5.0 through acidic liquid; the acidic fermentation liquid is pre-processed, wherein the temperature of the acidic fermentation liquid with the pH adjusted is preserved for 3-4 h at the temperature of 60-65 DEG C; the pH is adjusted till the salinomycin fermentation liquid is alkaline, a saponification reaction is performed, and salinomycin material liquid is prepared, wherein a certain amount of light calcium carbonate is added into the prepared acidic fermentation liquid so that salinomycin material liquid can be prepared; spraying and drying are performed, wherein after spraying particles are added into the prepared salinomycin material liquid, granules are prepared through a spraying and drying method, and then a salinomycin granule preparation is obtained. The salinomycin granule preparation preparation technology solves the problems that an existing salinomycin granule preparation technology is low yield and not ideal in spraying effect.

Description

technical field [0001] The invention relates to the technical field of medicine, in particular to a preparation process of salinomycin granule preparation based on improving the spray effect. Background technique [0002] Salinomycin is a polyether ionophore antibiotic produced by Streptomyces albus. Salinomycin granule preparation not only has good antibacterial effect, low toxicity and low residue, simple production process, readily available raw materials and low price, it is one of the most promising veterinary drugs recognized in the market. [0003] Salinomycin has a strong inhibitory and killing effect on most Gram-positive bacteria and various coccidiosis, and it is not easy to produce drug resistance and cross-resistance. It is excreted quickly and the residual amount is extremely low. It can be used to prevent diarrhea, Promote production and increase survival rate. Salinomycin has a cation transport function in cells, especially for potassium ions, sodium ions, ...
