Abstract

A synergistic norfloxacin drinking agent is prepared from norfloxacin (4-6%), trimethoprim (0.5-0.5%) and nicotinic acid (2-3%) except glucose and sodium chloride through mixing, granulating and drying, and features high curative effect, and high curative effect.

Description

Synergy norfloxacin drinking agent
The invention belongs to the veterinary drug technical field, is a kind of synergy norfloxacin drinking agent.
At present, in the veterinary drug technical field, have only the folk prescription norfloxacin injection, norfloxacin drinking agent, norfloxacin compound injection antibiotic with it give mixture etc.Said medicine has certain germicidal efficacy.
The purpose of this invention is to provide a kind of good water solubility, be convenient to the fowl poultry and drink, curative effect is better than the synergy norfloxacin drinking agent of folk prescription norfloxacin drinking agent.
The object of the present invention is achieved like this: the present invention is made up of norfloxacin, trimethoprim, nicotinic acid, glucose and sodium chloride,
Norfloxacin 4%-6%
The close pyridine 0.5%-1.5% of methoxy benzyl ammonia
Nicotinic acid 2%-3%
Glucose 61.5%
The sodium chloride surplus
Above-mentioned composition can adopt three kinds of its preparation process
1, nicotinic acid is made aqueous solution, be sprayed onto in norfloxacin and the methoxy benzyl pyrimidine, mixed pelletization, oven dry, crushing screening adds glucose and sodium chloride, mixing, chemical examination packing.
2, the husky star of promise chlorine, trimethoprim and nicotinic acid three mix, water is sprayed onto on the mixture, mixing, granulate, dry, sieve all to pieces, add glucose, sodium chloride mixing again, the chemical examination packing.
3, norfloxacin, trimethoprim and nicotinic acid mixing add glucose, sodium chloride mixing, chemical examination, packing again.
Good water solubility of the present invention is convenient to the fowl poultry and is drunk, through clinical verification, and clinical verification P of the present invention<0.01, curative effect is very remarkable.
Norfloxacin content of the present invention is identical with folk prescription norfloxacin drinking agent content, and trimethoprim is lower than 0.5% or be higher than at 1.5% o'clock, and drug effect strengthens not obvious; For making product have water solublity, it is an amount of that nicotinic acid is wanted, and its content is not less than 2%, is not higher than 3%.
The mechanism of action of norfloxacin is to suppress the DNA of bacteria gyrase, and blocking dna is synthetic, thereby produces the quick sterilization effect.
The mechanism of action of trimethoprim is to the dihydrofoilic acid in the bacterial metabolism process, reductase is inhibited, can block the metabolism of folic acid, the generation of bacterial nucleic acid is suppressed, with norfloxacin synergism is arranged, the two use in conjunction can make the synthetic and folic acid metabolism of the DNA of antibacterial be subjected to double blocking, and drug effect is strengthened.Nicotinic acid makes norfloxacin and trimethoprim have water solublity.Glucose and sodium chloride are the adjuvant filler, increase the flowability of medicine.The present invention is a broad spectrum antibiotic, G+ and G-pathogenic bacterium all there is killing action, can be used for treating diarrhoea such as Pullorum Disease, piglet, Hakuri, yellow scours, chicken, duck, goose, cattle, horse, sheep, septicemia, paratyphoid fever etc. are used when being particularly suitable for fowl poultry acute bacterial infectious disease or mixed infection.
Further specify technical characterictic of the present invention below in conjunction with embodiment.

Nicotinic acid is made aqueous solution, spray wine in norfloxacin and trimethoprim, mixed pelletization, oven dry, crushing screening adds glucose again, sodium chloride mixing, chemical examination packing.
The present invention carries out the clinical verification therapeutic test to the chickling salmonellosis.Get medicine 50 gram/bags of the present invention, get control drug folk prescription norfloxacin drinking agent, produce 50 gram/bags by Shandong veterinary drug subsidiary factory.Get standard lyophilization Pullorum Disease salmonella strain (S.Pullovum) bacterium G9-13, provide by China Veterinary Drugs Supervisory Inst..Getting standard Pullorum antigen and immune serum goes out the Harbin veterinary institute and provides.
Supply liquid preparation of examination bacterium and bacterium liquid to contain bacterium and count algoscopy, the lyophilizing bacterial strain is incubated at broth medium, put 37 ℃ of incubators and increase bacterium cultivation 24 hours, after smear for microscopic examination and affirmation have this bacterium breeding of growth type; It is inoculated in the plain agar slant medium, puts 37 ℃ and cultivated 18 hours, wash bacterium colony with sterile saline and make bacterium liquid (hereinafter to be referred as bacterium liquid), calculating bacterial concentration by plate surface count plate method is 3.4 hundred million jin/ml.
Laboratory animal is through the non-immune 6 age in days Bai Nike chickens of the no salmonellosis of quarantine, and body weight 50~60 restrains/only, provided by Shenyang City's herding institute.
Experiment provides no medicine mixed feed with feedstuff by Liaoning Province's great achievement farming and animal husbandry company limited, feeds after the assay was approved through feedstuff monitoring station, Liaoning Province, and day feed three times is freely drunk water.
Experiment condition, 18~32 ℃ of room temperatures, relative humidity 60~70% illumination manual adjustment.
Experimental technique: get 120 of experimental chickens, be divided into four groups at random.
The A group: artificial challenge's trial drug treatment group bacterium liquid adds medicine of the present invention.
The B group: the similar medication therapy groups bacterium of artificial challenge liquid adds the folk prescription norfloxacin.
C group: not medication of artificial challenge group, bacterium liquid.
More than three groups be the equal conditions drylot feeding.
A, B, C adopt the chest muscle injecting method to carry out Pullorum Disease salmonellosis artificial challenge for three groups simultaneously.Every chicken injection bacterium liquid 0.5ml (bacteria containing amount is 1.7 hundred million).
The artificial challenge is after 24 hours for A, B group, medication according to dosage respectively, twice of every day.
48~72 little phase secondary diseases behind A, B, three groups of artificial challenges of C, spirit is depressed, the wing that hangs down, dysnystaxis, just from green feces, nephrodinic ambient contamination, feather is fluffy and disorderly, the Pullorum Disease classical symptom occurs.A, B are organized continuous use five days, continue after the drug withdrawal to observe seven days, A organizes dead 2, B organizes dead 4, C organizes dead 21, after 13 days dead chicken and survival chicken are dissected one by one, observed the pathological change of its intestinal, kidney, liver and lung, indicate with "-" "+" " ++ " " +++" respectively according in various degree pathological changes.
Experimental result shows that the present invention is sick to the typical case of gram bacillus, and the Pullorum Disease salmonellosis has the obvious treatment effect, observe from pathological anatomy, the pathological change of C group is generally serious, and liver is hemorrhage, the white condition of illness that the needle point size occurs, hyperemia, the down visible white downright bad shape of lung serous coat, the dirty petechial hemorrhage of stomach, enteral is seen and is watered red chyle shape thing, caecum is seen the ulcer shape, and rectum sees that the cyan loose stool stops up intestinal, and two groups of only indivedual chickens of A, B have pathological changes.
