Problems solved by technology

Several common granule preparation processes and their existing defects: 1. Traditional granule preparation process, due to the high viscosity of traditional Chinese medicine extracts, most of the traditional granule preparation methods have low drug loading, unsightly appearance, and poor taste , easy to absorb moisture and other problems
5. In the field of preparations, there are also fluidized bed bottom spraying or side spraying techniques to manufacture western medicine pellets or spherical granules, which are mostly used in the development of sustained release preparations. Therefore, the developed products generally have slow and controlled release characteristics, and do not have immediate release characteristics.

Abstract

The invention provides a traditional Chinese medicine granular preparation with shrubby sophora extract and a preparation method thereof. Traditional Chinese medicine spheroidized particles are prepared by using a traditional Chinese medicine extract and a pharmaceutically acceptable carrier. The shapes of the traditional Chinese medicine spheroidized particles are spherical or similar to spheres, and the density of the traditional Chinese medicine spheroidized particles ranges from 0.6 g / ml to 1.3 g / ml. A single dose of the spheroidized particles is small, the medicine taking is convenient, and the granular preparation can be used as a semifinished product of capsules and can also be used for developing sustained and controlled release preparations of traditional Chinese medicine.

Description

technical field [0001] The invention relates to a traditional Chinese medicine preparation and a preparation method thereof, in particular to a traditional Chinese medicine granule containing Sophora flavescens extract and a preparation method thereof. Background technique [0002] Viral myocarditis (VMC) is myocardial cell degeneration and myocardial interstitial changes caused by viruses invading the myocardium, especially in children. According to related data reports: the incidence of the disease is increasing day by day, second only to coronary heart disease, rheumatic heart disease, etc., and most of the patients are young and middle-aged, which has seriously affected people's lives. [0003] Almost all kinds of viruses can cause viral myocarditis, among which coxsackie, influenza, echo, polio, mumps, and adenovirus are the main ones, especially coxsackie group B myocarditis is the most common. Numerous clinical data suggest that viral myocarditis can be transformed i...
