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 containing red paeonia extractive and a preparation method thereof. In the invention, traditional Chinese medicine spheroidized particles are prepared by traditional Chinese medicine extractive and carriers acceptable in pharmacy. The outline of the traditional Chinese medicine spheroidized particles takes sphere shape or round type shape. The density of the preparation is 0.6-1.3 g / ml. The spheroidized particles of the invention has low single dose, is convenient in use, can be served as intermediate products of capsules, and also can be used for developing a traditional Chinese medicine controlled release preparation.

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 Radix Paeoniae Rubra extract and a preparation method thereof. Background technique [0002] Stroke is a common and frequently-occurring disease that seriously endangers human health, and its disability and mortality are very high. According to pertinent data report: suffer from apoplexy patient, its death rate accounts for more than 62% of this patient group, reaches up to 80%, has caused misery to patient and family, has caused heavy burden to society.
