Description

A kind of Ursocycline chewable tablets for dog or cat

Technical field

The present invention relates to the preparation technique of veterinary drug, particularly relate to palatability that a kind of dog cat uses chewable tablet preferably.

Background technology

Raising pets has long history in China.Along with growth in the living standard, the quantity of famous and precious dog, cat house pet increases gradually, and pet owners is also more and more paid attention to the quality of life of house pet.The dog cat is a mammal, the common disease that oneself is also arranged, the treatment of dog cat disease at present are mainly based on intravenous drip and intramuscular injection, and this therapeutic scheme often needs to raise the master and treats for the house pet of oneself time of arranging out specially, and, often cause the prognosis mala of disease in case treatment is interrupted.If can make initiatively oral administration medicine of dog cat, will solve this a series of problem, but tablet for animals few in number in the market often be difficult to apply because of its palatability difference.

Summary of the invention

The inventor is at the physiological characteristics of dog cat, broken through the shortcoming of existing tablet palatability difference, developed the chewable tablet that is applicable to dog cat taste, can make it fully chew post-absorption, effectively raise medicine utilization rate, guaranteed dosage, improved the cure rate of dog cat disease.

The object of the present invention is to provide a kind of chewable tablet that is used for dog cat disease treatment, it has good palatability, advantage that curative effect is high.

The composition of tablet of the present invention comprises: represent to be respectively aspartame 1-5% with percentage by weight, oral glucose and defatted milk powder mixture 20～30%, the ratio 1 of oral glucose, defatted milk powder: 1-1: 4 in the mixture; Excipient 40%～60%, fluidizer 0.5-1%, oxytetracycline 30-50%.

Described excipient comprises starch, dextrin, Icing Sugar, calcium sulfate or their mixture.

Described fluidizer comprises magnesium stearate, Pulvis Talci, micropowder silica gel or their mixture.

In order to obtain better effect, preferred ingredient is: aspartame 1-5%, oral glucose and defatted milk powder mixture 20～30%, the ratio 1 of oral glucose, defatted milk powder: 1-1: 4 in the mixture; Starch 40%～60%, magnesium stearate 0.5-1%, oxytetracycline 30-50%.

More preferably: aspartame 3%, oral glucose and defatted milk powder mixture 20%, the ratio 1 of oral glucose, defatted milk powder: 1-1: 4 in the mixture; Starch 40%, magnesium stearate 0.5%, oxytetracycline 36.5%

Tablet of the present invention can adopt the general process of industry, equipment preparation.The following method preparation of preferred employing comprises step:

1) with starch in 100 ℃ of dryings 1 hour, be cooled to room temperature; Afterwards respectively with the excipient of oxytetracycline, aspartame and equivalent with equivalent progressively increase the dilution method dilution, mixes, mistake 60 order fine screens three times obtain mixture A;

2) with mixture A and remaining excipient, oral glucose, defatted milk powder mix homogeneously, mixture B is standby;

3) glycerol and dehydrated alcohol are pressed 1: the mixed of 5-10 is even, adds polyvinylpyrrolidone afterwards, makes polyvinylpyrrolidone glycerol alcohol mixed solution, as binding agent;

4) the polyvinylpyrrolidone glycerol alcohol mixed solution of its volume 1/2 of adding in mixture B, mix homogeneously is as soft material;

5) granulate with 16 mesh sieves, 50 ℃ of aeration-dryings get dried particles.Accurately take by weighing lubricant and join in the dried granules, mixing, with 18 mesh sieve granulate, tabletting is promptly.

Beneficial effect: tablet of the present invention has been broken the blank of field of veterinary chewable tablet, broken through the shortcoming of existing oral tablet palatability difference, physiological characteristics at the dog cat, develop the chewable tablet that is applicable to dog cat taste, making it chew the back fully absorbs, effectively raise the cure rate of disease, reduced the waste of medicine.

The specific embodiment

In order to understand the present invention, further specify the present invention with embodiment below, but do not limit the present invention.

Embodiment 1: Ursocycline chewable tablets

Get starch 2400g in 100 ℃ of bakings 1 hour, be cooled to room temperature; Other fetch earth mycin 1800g, aspartame 60g, with cooled starch with equivalent progressively increase the dilution method dilution, mixes, cross 60 orders afterwards, fine screen three times must mixture A.Mixture A and oral glucose 600g, defatted milk powder 600g and starch 540g are put into the mixer mix homogeneously, mixture B, standby.Glycerol and dehydrated alcohol are got 2.5L after by 1: 10 mixed, make polyvinylpyrrolidone glycerol alcohol mixed solution to wherein adding polyvinylpyrrolidone 200g.

Stir down that gradation adds polyvinylpyrrolidone glycerol alcohol mixed solution in mixture B, to all adding, mix homogeneously, soft material that humidity is moderate.16 mesh sieves are granulated, 50 ℃ of aeration-dryings.Accurately take by weighing magnesium stearate 60g and be added in the dried granules, mixing is with 18 mesh sieve granulate, tabletting.Film-making is about 10000 altogether, and every heavy 0.6g contains oxytetracycline 0.18g.

Tablet of the present invention is mainly used in infection such as treatment gram positive bacteria, the negative sclerotium person of propping up body, as pasteurellosis bacillus, escherichia coli and Salmonella infection etc.For oral administration: as once to measure every 1kg body weight, dog 15-50mg, one day 2-3 time, logotype 3-5 day.

Test example 1:

The experiment medicine: the experimental group medicine adopts the Ursocycline chewable tablets of embodiment 1 preparation; The matched group medicine adopts oral of oxytetracycline.

Laboratory animal: choose 6 adult dogs of suffering from the different cultivars of slight pneumonia

Experiment: it is depressed that the cardinal symptom of six sick dogs shows as spirit, loss of appetite, and hypopnea, cough is divided into it two groups at random, 3 every group, is respectively experimental group and matched group.Experimental group is taken Ursocycline chewable tablets of the present invention, 35mg/kg body weight, a twice-daily, logotype 5 days; Matched group is taken oral of oxytetracycline, 35mg/kg body weight, a twice-daily, logotype 5 days.

Experimental result: Ursocycline chewable tablets palatability of the present invention is better, is fit to the taste of dog, and feeding gets final product in the process of administration, and the sick dog of experimental group is all recoveries from illness after 5 days, and appetite is recovered; Matched group is relatively poor because of oral mouth of oxytetracycline, and taste is bitter, mix food and drink water all can not reach effective therapeutic dose, so therapeutic effect is not good, and the dysentery symptom is not significantly improved.

	Symptom	The experiment number of elements	Usage and dosage	The result
					Experimental group	Spirit is depressed, is and goes down, cough	3	The 35mg/kg body weight, one day twice, logotype 5 days	Experimental dog is all fully recovered after the course of treatment, recovers diet
Matched group	Spirit is depressed, is and goes down, cough	3	The 35mg/kg body weight, one day twice, logotype 5 days	DeGrain, the cough symptom is not obviously improved

By above-mentioned experiment as can be seen, tablet of the present invention has palatability preferably, therefore can play therapeutical effect timely to disease.
