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 notoginseng 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 Panax notoginseng extract and a preparation method thereof. Background technique [0002] Coronary heart disease is a common disease, and it is also one of the diseases that seriously harm the middle-aged and elderly people. In recent years, due to social development, changes in work, life, diet and environment, the number of patients with coronary heart disease is on the rise. According to relevant statistics, the incidence rate of coronary heart disease patients over middle age is 2.47%-3.18%. At present, the western medicines for treating coronary heart disease are mainly nitrate compounds, beta-receptor blockers and calcium antagonists, etc. These medicines can only relieve symptoms, but are difficult to cure the root cause, and have certain toxic and side effects. Although the si...
