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 ginseng 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 ginseng extract and a preparation method thereof. Background technique [0002] Ginseng is Araliaceae Panax ginseng C.A. Meyer. As early as two thousand years ago, our ancestors discovered and used ginseng to prevent and treat diseases. Chinese people also have the habit of taking ginseng supplements, and doctors of all dynasties said that it has the power of "replenishing vitality". my country's earliest pharmacy classic "Shen Nong's Materia Medica" stated that ginseng "mainly nourishes the five internal organs, calms the spirit, calms the soul, relieves panic, improves eyesight and improves intelligence, long-term use makes light of body and prolongs life." Later, in "Famous Doctors", "Treatise on Febrile Diseases ", "Tang Materia Medica" and "Compendium of Materia Medica" and other m...
