Problems solved by technology

During packaging, especially when subpackaging by the intelligent blending system, due to the irregular shape of the granules, the rough surface of the granules, the uneven size, and the poor fluidity, there are problems of large differences in the filling volume, and powder is easily produced during the subpackaging and metering process. Adhering to metering equipment and pipelines, causing cross-contamination and drug mixing, especially particles with certain toxicity, such as aconite, aconitum and other particles; at the same time, Chinese medicine formula particles are easy to absorb moisture, and there is stability sexual problems

Abstract

The invention discloses a preparation method of pellet-type formula granules. The method comprises the following steps: (1) selecting at least one of the traditional Chinese medicinal materials; (2) respectively extracting the medicinal materials selected in step (1) for obtaining extracts, or respectively grinding the medicinal materials, or respectively carrying out partial extraction and partial grinding, thus obtaining pretreated materials; and (3) preparing the pretreated materials obtained in step (2) into pellets, thus obtaining the pellet-type formula granules. According to the preparation method provided by the invention, on the basis of the prior art, the preparation process of the formula granules is innovated, the formula granules are innovated into pellets, the fluidity and moisture absorption resistance are good, the friability is small, the shape is round and uniform as well as regular, the content uniformity is small, and the divided dose is accurate.

Description

technical field [0001] The invention relates to a preparation method of traditional Chinese medicine, in particular to a preparation method of pellet-shaped formula granules. Background technique [0002] Traditional Chinese medicine formula granules (formerly known as granular decoction pieces) refer to granules made from traditional single-flavor Chinese medicine decoction pieces that meet the processing specifications and processed by modern pharmaceutical technologies such as extraction or crushing. Traditional Chinese medicine formula granules maintain the characteristics of traditional decoction pieces and decoctions in the preparation process. Except for the varieties that are traditionally used as powder, other varieties are prepared by modern dry or wet granulation technology after decoction. For varieties containing volatile oil, the volatile oil is first extracted and then decocted, and finally the volatile oil is sprayed to retain the volatile components of the C...
