Abstract

The invention relates to a sarafloxacin hydrochloride sustain-released injection and a preparation method thereof, belongs to a medicinal preparation field. The sarafloxacin hydrochloride sustain-released injection is composed of sarafloxacin hydrochloride, an emulsifier, a suspending agent, a stabilizing agent, an antioxidant, plant oil for injection, and injection water. The preparation method comprises the following steps of: heating sieved sarafloxacin hydrochloride raw material drug, the plant oil for injection, the emulsifier and the antioxidant in a constant temperature magnetic stirrer, to obtain a mixture A; heating the suspending agent, a water-soluble emulsifier, the stabilizing agent and the injection water in the constant temperature magnetic stirrer, to obtain a mixture B; continuously adding the mixture A into the mixture B, mixing and shearing to obtain colostrums; complementing margin of the colostrum with injection water, then homogenizing, loading, and disinfecting with cobalt 60 ray, to obtain the product. The sarafloxacin hydrochloride injection with obvious sustain-released effect on intramuscular injection of livestock and poultry, can reduce stress reaction, mitigates culture labor intensity, and raises economic benefits and social benefits for livestock and poultry culture.

Description

technical field [0001] The invention belongs to the field of pharmaceutical preparations, in particular to a sarafloxacin hydrochloride sustained-release injection and a preparation method thereof. Background technique [0002] Sarafloxacin hydrochloride is a third-generation fluoroquinolone antibacterial drug specially used for animals. It has a broad antibacterial spectrum and strong antibacterial activity. It has good performance against Gram-negative bacteria, Gram-positive bacteria and mycoplasma. Antibacterial effect, especially for Escherichia coli, Salmonella, Klebsiella, Proteus, Pasteurella multocida, Campylobacter and other enterobacteria. Sarafloxacin hydrochloride absorbs quickly, metabolizes quickly, has almost no residue, and has no cross-resistance with many antibacterial drugs. Rapid absorption after oral administration and injection, serum and tissue concentrations significantly higher than the MIC value for most pathogenic bacteria, wide distribution in t...
