Abstract

The invention discloses a method for preparing a veterinary lung-clearing pellet and a product thereof. The preparation method comprises the following steps: (1) extracting effective components of bulk drugs to prepare extract for later use; (2) preparing a pellet core; (3) adding talc powder into the extract, uniformly mixing to obtain a mixture, loading the mixture to the surface of the core in a spraying manner in a fluidized bed, and drying. According to the preparation method, process parameters of the veterinary lung-clearing pellet are optimally screened, and the prepared pellet has the advantages of high yield, roundness and smoothness, small rest angle and the like. Clinical effect verification for treating mycoplasma pneumoniae of swine indicates that the lung-clearing pellet prepared by the method has a remarkable clinical treatment effect on mycoplasma pneumoniae of swine, which is superior to the clinical curative effect of lung-clearing powder.

Description

technical field [0001] The invention relates to a preparation method of veterinary traditional Chinese medicine pellets, in particular to a preparation method of veterinary Qingfei powder pellets and a product thereof, belonging to the preparation field of veterinary Qingfei powder. Background technique [0002] The 2010 edition of the "People's Republic of China Veterinary Drug Code" published the prescription of the veterinary drug Qingfei San, which is made from a mixture of Radix Isatidis, Tinglizi, Fritillaria, Campanulaceae, and Licorice. It has the effect of relieving cough, but the dosage of the powder is large, and the active ingredients cannot be well absorbed. In order to achieve the expected effect, the dosage of the medicine needs to be increased, resulting in higher cost and waste of resources. Chinese medicine extracts and their preparations can not only maintain the traditional medicine characteristics of Chinese veterinary medicine, but also extract and reta...
