Abstract

The invention discloses a drug moisture-proof agent and a preparation method and application thereof,and belongs to the field of moisture-proof technologies of traditional Chinese medicine preparations. The drug moisture-proof agent comprises zein,soluble starch,calcium hydrophosphate,lactose,magnesium stearate,microcrystalline cellulose,hydroxypropyl cellulose,povidone,cane sugar,micro-powder silica gel,hydrophobic nano silicon dioxide and maltodextrin. The drug moisture-proof agent is prepared in the steps of dissolving,modifying,mixing,stirring and the like. A reinforcing system composed ofthe micro-powder silica gel,the hydrophobic nano silicon dioxide and the maltodextrin is applied to the drug moisture-proof agent,the viscosity and moisture absorption rate of the drug moisture-proofagent are further reduced,and the drug stability is improved.

Description

technical field [0001] The invention belongs to the technical field of moisture-proofing of traditional Chinese medicine preparations, and in particular relates to a medicinal moisture-proofing agent and a preparation method and application thereof. Background technique [0002] According to a certain proportion of traditional Chinese medicine decoction pieces, the preparation raw materials prepared by water extraction or alcohol extraction, concentration, drying and other processes are Chinese medicine extracts. Compared with chemical medicines with single ingredients and clear physical and chemical properties, their ingredients are very complex. And most of the traditional Chinese medicine extracts show bad physical properties such as strong hygroscopicity and poor fluidity. For example, the polysaccharides, tannins, pectin, mucus, resins and other components rich in Chinese medicine extracts are very easy to absorb moisture, and some small molecule alkaloids are also high...
