Preparation method of cold-resistant-free veterinary drug

Abstract

The invention discloses a preparation method of a cold-resistant-free veterinary drug. The preparation method comprises the following steps of: step 1, removing impurities; step 2, drying; step 3, grinding; step 4, extracting; step 5, purifying; step 6, drying; and step 7, granulating. According to the preparation method disclosed by the invention, through ultrasonic wall breaking treatment, the extraction rate of effective components is increased, the content of ineffective components in the veterinary drug is reduced, the medicinal value of the veterinary drug is increased, the veterinary drug is enabled to effectively prevent, treat and diagnose animal diseases or purposefully regulate physiological functions of animals, and the medicinal requirements of the animals are met; through purification and refining by an ultrafiltration membrane, macromolecular microparticles such as protein, water-soluble polymers and bacteria in raw materials are removed, the content of the effective components in the veterinary drug is increased, and the absorption of the effective components in the veterinary drug by the animals is facilitated; and impurities such as dust, scurf, fluff and sandy soil mixed in the raw materials are thoroughly removed by using impurity removing liquid, the purity of the raw materials is increased, and the medicinal value of the cold-resistant-free veterinary drugis increased.

Description

technical field [0001] The invention relates to the technical field of medicine preparation, in particular to a preparation method of non-cold-resistant veterinary medicine. Background technique [0002] With the continuous improvement of the per capita disposable income of urban and rural residents in our country, the huge demand for meat consumption has driven the expansion of the scale of economic animals in our country year by year, which directly promotes the continuous growth of the demand for veterinary drugs. Veterinary drugs refer to substances used to prevent, treat, and diagnose animal diseases or purposefully regulate animal physiological functions, mainly including: serum products, vaccines, diagnostic products, micro-ecological products, Chinese medicinal materials, Chinese patent medicines, chemicals, antibiotics, biochemical Drugs, radioactive drugs, insecticides for external use, disinfectants, etc., can be roughly divided into two types according to their u...

AI Technical Summary

Problems solved by technology

[0003] At present, most of the traditional preparation methods of non-cold-resistant veterinary drugs are prepared by mashing and grinding, the extraction rate of active ingredients is low, and the prepared veterinary drugs contain a large number of ineffective ingredients, which have limited medicinal value and cannot effectively prevent and treat , Diagnose animal diseases or purposely adjust animal physiological functions, it is difficult to meet the medicinal needs of animals, and the raw materials have not been purified, and there are a large number of polymer particles such as proteins, water-soluble polymers and bacteria in veterinary drugs, affecting The absorption of active ingredients by animals is hindered, and at the same time, the cleaning of raw materials is insufficient, and impurities such as dust, dander, fluff and sand mixed in raw materials are not completely removed, which inevitably affects the purity of raw materials and reduces the quality of non-cold resistant Medicinal value of veterinary medicine
