Problems solved by technology

In the production of chitosan oligosaccharide preparations, phenomena such as layering, turbidity, precipitation, and uneven color are prone to occur, making the chitosan oligosaccharide preparations poor in stability; Chinese patent document CN111617030A disclosed chitosan oligosaccharides on September 4, 2020 Oral liquid and its application in the preparation of weight-loss drugs, the oral solution of oligochitosan is easily degraded by gastric acid, resulting in a decrease in the amount of oligochitosan acting on the intestinal flora and reducing the efficacy of the drug; Chinese patent document CN108653317A was published in October 2018 On the 16th, a chitosan oligosaccharide oral solution and its preparation method were disclosed. It was prepared from 25-40 parts of chitosan oligosaccharide, 1-3 parts of flavoring agent, 2-4 parts of preservative, and 1.5-2 parts of stabilizer. The addition of a large amount of excipients will lead to a decrease in the content of the main drug in the same volume, and it will also be easily degraded by the stomach

Abstract

The invention discloses a chitosan oligosaccharide enteric capsule which comprises a content and a capsule shell, the content comprises an enteric auxiliary material, chitosan oligosaccharide and a release regulator, and the mass ratio of the enteric auxiliary material to the chitosan oligosaccharide to the release regulator is (3-5): 1: 1; the chitosan oligosaccharide enteric capsule content is prepared by a freeze drying method, compared with a traditional preparation process, the dosage of auxiliary materials can be reduced to a great extent, the process is reasonable and stable, the smell of chitosan oligosaccharide can be well covered, the patient compliance is improved, and the chitosan oligosaccharide enteric capsule content has the enteric preparation characteristics of being insoluble in the stomach and instant in the intestine; the smell of the chitosan oligosaccharide can be well covered, the compliance of a patient is improved, the degradation of the chitosan oligosaccharide in gastric acid can be reduced, and the release and absorption of a molecular prototype of the chitosan oligosaccharide in intestinal tracts can be increased.

Description

technical field [0001] The invention relates to the technical field of pharmaceutical preparations, in particular to a chitosan oligosaccharide enteric-coated capsule and a preparation method and application thereof. Background technique [0002] Obesity is a relatively complex chronic endocrine disease, the main cause and manifestation of which is excessive accumulation of body fat, which is closely related to metabolic diseases such as diabetes, non-alcoholic fatty liver, and hyperlipidemia. Adverse effects caused by obesity are mainly divided into two categories: one is symptoms caused by excessive accumulation of adipose tissue in the body (such as osteoarthritis, obstructive sleep apnea, stigma caused by physical appearance), and the other is caused by Diseases (T2DM, cardiovascular disease, non-alcoholic fatty liver disease) caused by excessive increase in the number of fat cells in other tissues and organs in the state of obesity. In addition, the strength of the ass...
