Abstract

The invention provides a traditional Chinese medicine granular preparation with angelica 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 angelica extract and a preparation method thereof. Background technique [0002] Headache is a common symptom in daily life, almost everyone will have a headache in their life. There are various causes of headaches. At present, there are many traditional Chinese medicine preparations for the treatment of headaches in China, but their slow onset is their main shortcoming, which affects the quality of life of patients. [0003] The traditional preparation method of traditional Chinese medicine granules is to make traditional Chinese medicine or its extracts into granular substances with a certain particle size by dry or wet methods, which are used by patients to drink or swallow with water. Several common granule preparation processes and their existing defects: 1. Traditional granule p...
