Embodiment 1

[0018] Example 1: Erythromycin Chewable Tablets

[0019] Take 2400g of starch and bake at 100°C for 1 hour, cool to room temperature; take another 600g of erythromycin and 60g of aspartame, dilute and mix with the cooled starch by equal incremental dilution method, pass through 60 mesh, and finely sieve Mixture A was obtained three times. Put mixture A, 600 g of oral glucose, 600 g of skimmed milk powder and 1740 g of starch into a mixer and mix evenly to obtain mixture B, which is set aside. 2.5 L of absolute ethanol was taken, and 200 g of polyvinylpyrrolidone was added therein to make a polyvinylpyrrolidone-ethanol mixed solution.

[0020] Add the polyvinylpyrrolidone-ethanol mixed solution to the mixture B step by step under stirring until all the addition is complete, and a soft material with uniform mixing and moderate humidity is obtained. Granulate with a 16-mesh sieve and ventilate and dry at 50°C. Accurately weigh 30g of magnesium stearate and add to the dried gra...

Embodiment 2

[0029] Embodiment 2: erythromycin chewable tablet

[0030] Get starch 1410g, erythromycin 1200g, aspartame 210g and prepare mixture A by the method described in Example 1.

[0031] Put mixture A, 375g of oral glucose, 1125g of skimmed milk powder and 1950g of starch into a mixer and mix evenly to obtain mixture B, which is set aside. Take 2.5 L of absolute ethanol, and add 200 g of polyvinylpyrrolidone to it to make a polyvinylpyrrolidone-ethanol mixed solution as a binder.

[0032] Add the polyvinylpyrrolidone-ethanol mixed solution to the mixture B step by step under stirring until all the addition is complete, and a soft material with uniform mixing and moderate humidity is obtained. Accurately weigh 30 g of magnesium stearate for granulation, granulate, dry, granulate, and compress according to the method described in Example 1. About 10,000 tablets were made, each weighing 0.6g, containing 0.12g of erythromycin.

Embodiment 3

[0033] Embodiment 3: erythromycin chewable tablet

[0034] Get starch 2100g, erythromycin 1800g, aspartame 300g, prepare mixture A by the method described in Example 1. Put mixture A, 360 g of oral glucose, 1440 g of skim milk powder and 1500 g of starch into a mixer and mix evenly to obtain mixture B, which is set aside. Take 2.5 L of absolute ethanol, and add 200 g of polyvinylpyrrolidone to it to make a polyvinylpyrrolidone-ethanol mixed solution as a binder.

[0035] Add the polyvinylpyrrolidone-ethanol mixed solution to the mixture B step by step under stirring until all the addition is complete, and a soft material with uniform mixing and moderate humidity is obtained. Accurately weigh 30 g of magnesium stearate for granulation, granulate, dry, granulate, and compress according to the method described in Example 1. A total of about 10,000 tablets were made, each weighing 0.6g and containing 0.18 erythromycin.

Abstract

The invention discloses an erythromycin chewable tablet used for dogs and cats. The invention overcomes the poor palatability defect of the existing tablet to promote the thorough chewing absorption by dogs and cats, so as to effectively guarantee the medicine-supply dose, to enhance the cure rate of diseases of dogs and cats and to reduce the medicine waste. The tablet of the invention comprises the following components represented by weight-percentage: 1 to 5 percent of aspartame; 20 to 30 percent of a mixture of oral dextrose and degreased milk powder; the ratio of 1:1 to 1:4 between the oral dextrose and degreased milk powder in the mixture; 40 to 60 percent of excipient; 0.5 to 1 percent of glidant and 10 to 30 percent of erythromycin.

Description

technical field [0001] The invention relates to the preparation technology of veterinary medicine, in particular to a chewable tablet with good palatability for dogs and cats. Background technique [0002] Pet breeding has a long history in our country. With the improvement of living standards, the number of expensive dogs and cats is gradually increasing, and pet owners are paying more and more attention to the quality of life of their pets. Dogs and cats are mammals, and they also have their own common diseases. At present, the treatment of dog and cat diseases is mainly based on intravenous drip and intramuscular injection. Interruption of treatment often results in a poor prognosis of the disease. If dogs and cats can be made to actively take therapeutic drugs orally, this series of problems will be solved, but the few veterinary tablets currently on the market are often difficult to popularize because of their poor palatability. Contents of the invention [0003] A...
