Abstract

The invention belongs to the technical field of medicine preparation, and particularly relates to microcapsule decoction tables for embedding components for preventing and improving Alzheimer's disease and dementia and a preparation method of the microcapsule decoction tables. The microcapsule decoction tables are prepared by taking poly gamma-glutamic acid / chitosan as a carrier and loading a traditional Chinese medicine extract, wherein the traditional Chinese medicine extract comprises the following raw materials: radix ginseng, radix salviae miltiorrhizae roots, herba epimedii, rhizoma curcumae longae dried rhizomes, coffee beans, broccoli buds, acorn and bolete. The gamma-PGA-CS micro-capsule decoction tables prepared by the preparation method disclosed by the invention have a good slow-release effect on embedded traditional Chinese medicine components, and the preparation method is simple and low in raw material cost. The microcapsule decoction tables provided by the invention are high in medicine loading capacity, capable of embedding multiple medicines at the same time, high in bioavailability and capable of reducing side effects to the maximum extent so as to achieve the effects of preventing and improving Alzheimer's disease and dementia and the like.

Description

technical field [0001] The invention belongs to the technical field of medicine preparation and relates to a novel composite carrier material, in particular to a microcapsule decoction piece capable of embedding components for preventing and improving Alzheimer's disease and dementia and a preparation method thereof. Background technique [0002] In today's life, with the advent of the aging era, Alzheimer's disease has become a burden worldwide. Alzheimer's disease (AD) is not equal to dementia, or it is just one of its branches. AD is an insidious progressive neurodegenerative disease. Clinically, it is characterized by comprehensive dementia such as memory impairment, aphasia, apraxia, agnosia, impairment of visuospatial skills, executive dysfunction, and personality and behavior changes. The etiology is still unknown. It may be due to the fact that when certain proteins accumulate too much in and out of brain cells, it is difficult for brain cells to maintain healthy a...
