Method for preparing granules for curing infantile lung pathogenic heat and cough and asthma

Abstract

The invention discloses a method for preparing granules for curing infantile lung pathogenic heat and cough and asthma. The method comprises the following steps: weighing the following Chinese medicinal materials in part by weight: 30 parts of ephedra, 60 parts of bitter almond kernel, 240 parts of raw gypsum, 30 parts of liquorice root, 100 parts of honeysuckle, 100 parts of weeping forsythiae capsule, 100 parts of anemarrhena root, 100 parts of baikal skullcap root, 100 parts of indigowoad root, 100 parts of dwarf lilyturf tuber and 100 parts of cordate houttuynia; dividing the eleven Chinese medicinal materials into two groups; after performing water extraction on the two groups of Chinese medicinal materials, combining filtrates; mixing an extract prepared by concentrating the filtrate with a proper amount of dextrine and sodium cyclamate; preparing the mixture into granules; and drying the granules to obtain the granules for curing the infantile lung pathogenic heat and cough and asthma. In the method, water use amount in the process of performing water extraction on the Chinese medicinal materials is strictly controlled and extraction in different groups is carried out according to characteristics of different medicinal materials, so compared with a traditional water extraction method, the method has a better effect. The prepared granules for curing the infantile lung pathogenic heat and cough and asthma have stable and controllable quality, and stable baicalin distinguish project which meets requirements of standard. The method greatly improves qualification rate of the product, and has simple operation and is suitable for industrial production.

Description

technical field [0001] The invention relates to the field of preparation of pharmaceutical preparations, in particular to a preparation method of Xiaoer Feire Kechuan Granules.

AI Technical Summary

Problems solved by technology

[0005] The above-mentioned clear paste is a water extraction product, and the Xiaoerfeirekechuan granules made are produced according to the prior art because the product quality standard contains the identification item of baicalin, and baicalin is insoluble in water (dissolved under alkaline conditions). Can not be fully extracted, resulting in unstable identification items of baicalin in the product, resulting in unstable preparation quality and low product pass rate
