preparation example Construction

[0036] Cefquinome sulfate breast injection (dry milk stage) provided by the invention is a kind of uniformly distributed preparation, and concrete preparation method comprises the following steps:

[0037] A. Let the vegetable oil (such as neutral soybean oil) cool after filtration and heat sterilization;

[0038] B. Take an appropriate amount of pretreated vegetable oil and add 0.03-0.3g of glyceryl monostearate;

[0039] C. Heat at 60-80°C for 15-30 minutes, wait for the glyceryl stearate to melt, stir evenly, cool to about 40°C, add 0.03-0.3g suspending agent (such as Span 80), 0.05-0.3 g (in terms of cefquinome) of cefquinome sulfate (5-10 μm in particle size), add vegetable oil to a total amount of 3.0ml;

[0040] D. grind evenly, make cefquinome sulfate breast injection;

[0041] F. Put the medicine into the injection tube, seal it, sterilize it, inspect it with light, and pack it.

[0042] In the following examples, the detection method of the sedimentation particle ...

Abstract

The invention discloses a cefquinome-sulfate breast injection agent for the dry period of dairy cows and a preparation method thereof. The cefquinome-sulfate breast injection agent is prepared from the following raw auxiliary materials by weight: 0.05 to 0.3g of cefquinome sulfate (calculated by cefquinome), 0.03 to 0.3g of glyceryl monostearate, 0.03 to 0.3g of suspending agent and vegetable oil added to 3.0ml. The preparation process comprises the following steps : taking proper amount of vegetable oil pretreated, adding glyceryl monostearate, heating for melting, then adding the suspending agent and the cefquinome sulfate, then adding the vegetable oil to the total amount, grinding to be uniform and obtaining the cefquinome-sulfate breast injection agent. The cefquinome-sulfate breast injection agent disclosed by the invention has the following advantages that the drug release is slow, the bioavailability is high and the stimulation to local tissues is small; single medication is adopted for each breast area for each cow, so that cross infection is avoided; by breast injection, the use is convenient, the animal stress response caused by injection administration is avoided, and convenience is provided for clinical medication; and the curative effect is obvious and the promotion value is extremely high.

Description

technical field [0001] The invention relates to a cefquinome sulfate breast injection (dry milk period) and a preparation method thereof. Background technique [0002] Cow mastitis is an inflammatory change in mammary glands that is stimulated by physical, chemical, and microbiological factors. It is one of the most common and harmful diseases in dairy farming. In clinical practice, it is seen that the sick cows are depressed, their body temperature rises, and their appetite is lost; their lactation is reduced, their milk is thin, they feel hot and swollen when touched, and their milk contains flocs or milk clots, etc., resulting in a decrease in milk production and milk quality. , has seriously affected the healthy development of the dairy industry. This disease not only causes great economic losses to the breeding industry, but also seriously endangers human health. Therefore, the prevention and treatment of dairy cow mastitis is particularly important. [0003] The dry ...
