preparation example Construction

[0040] The present invention also provides the preparation method of described ceftaroning breast injection, comprises the steps:

[0041] Mix the emulsifier and the oily solvent, and homogenize the obtained mixture for the first time to prepare a homogeneous liquid;

[0042]Mix the homogenized liquid and cefuroxime, and homogenize the obtained mixture for the second time to prepare the cefuroxime breast injection.

[0043] In one specific example, the conditions for the first homogenization include: the pressure is 450bar-550bar. Specifically, the pressure of the first homogenization includes but is not limited to: 450 bar, 460 bar, 470 bar, 480 bar, 490 bar, 500 bar, 510 bar, 520 bar, 530 bar, 540 bar, 550 bar.

[0044] In one specific example, the number of times of the first homogenization is 1.

[0045] In one specific example, the conditions for the second homogenization include: a pressure of 950 bar to 1050 bar. Specifically, the pressure of the second homogenizatio...

Abstract

The invention relates to a cefalonium breast injectant as well as a preparation method and application thereof. According to 3 g of the cefalonium breast injectant, the cefalonium breast injectant is prepared from 120 mg to 360 mg of cefalonium, 120 mg to 360 mg of an emulsifying agent and an oily solvent, wherein the emulsifier is a mixture of tween, span and lecithin in a mass ratio of (3-5): (2-4): 1. The cefalonium breast injectant is good in dispersity in mammary glands, not prone to sedimentation in the long-term storage process and good in stability. Meanwhile, the traditional Chinese medicine has the advantages of good curative effect and short milk discarding period.

Description

technical field [0001] The invention relates to the technical field of pharmaceutical preparations, in particular to a ceftaroning breast injection and a preparation method and application thereof. Background technique [0002] Cow mastitis is a common and frequently-occurring disease of dairy cows. It is difficult to prevent and treat, and the cost of treatment is high. The dry period is the period when cows stop lactating before giving birth. It usually lasts for about 2 months. It is an important period for mammary gland recovery and the best period for the prevention and treatment of mastitis in dairy cows. The main purpose of dry period treatment is to reduce the level of existing breast infection and prevent new infection. To achieve these two goals, it is necessary to use broad-spectrum, long-acting antibacterial drugs for dry period treatment. [0003] Cefuronine is the first generation of semi-synthetic cephalosporin antibiotics. It has a strong killing effect on S...
