Description
Technical Field
The invention relates to the field of pharmaceutical preparations, in particular to an acetylglucosamine orally disintegrating tablet and a preparation method thereof.
Background
Acetylglucosamine is the smallest constitutional unit of chitin component in exoskeletons of insects and crustaceans, and is also the basic constitutional unit of many important polysaccharides in biological cells, and it has many important physiological functions in the organism. Pharmacodynamic tests, pharmacokinetic tests and the like show that the traditional Chinese medicine composition can be used for treating diarrhea-predominant irritable bowel syndrome, and has obvious effect and low toxic and side effects.
Chinese patent document CN107320456A discloses an N-acetyl-D-glucosamine capsule preparation and a preparation method thereof. However, no report is found about an acetylglucosamine tablet and a preparation method thereof.
Disclosure of Invention
In view of the above disadvantages of the prior art, the present invention aims to provide an acetylglucosamine orally disintegrating tablet, which comprises the following components in percentage by weight based on the total amount of the acetylglucosamine orally disintegrating tablet:
10 to 35 percent of acetyl glucosamine,
10-35% of alcohol diluent,
10-30% of filling agent,
2 to 20 percent of disintegrating agent,
3 to 20 percent of adhesive,
0.5 to 5 percent of lubricant,
0.5 to 1.5 percent of flavoring agent.
The second aspect of the present invention provides a method for preparing an orally disintegrating tablet of acetylglucosamine, comprising the steps of:
a. sieving the acetylglucosamine with a 80-mesh sieve;
b. mixing the acetylglucosamine with alcohol diluent, filler, disintegrating agent and adhesive to obtain premixed powder;
c. mixing the premixed powder with lubricant and correctant to obtain total mixed powder;
d. tabletting the total mixed powder to obtain the acetyl glucosamine orally disintegrating tablet.
The beneficial effects of the invention are as follows:
the formula of the orally disintegrating tablet of acetylglucosamine, particularly the specific component proportion, the comprehensive selection of silicified microcrystalline cellulose 90 and the like, generates excellent effects, particularly beneficial effects on the aspect of increasing the hardness of tablets. Generally, the hardness of the tablet is higher, so that the product is more favorably integrally formed and is not fragile, but the hardness is too high, so that the disintegration and the release of the tablet are influenced to a certain extent, and therefore, the hardness is controlled in the production process of the tablet. The invention can reach high hardness on the premise of ensuring the disintegration degree, and has excellent effect.
The alcohol diluent is used for improving the taste of the preparation and improving the hardness of the tablet. The microcrystalline cellulose 90 is silicified by using the filler, so that the acetylglucosamine is uniformly dispersed in the mixed powder, the flowability is good, the powder can be directly tabletted, and the disintegration is good. The disintegrating tablet prepared by the invention has the hardness as high as 70-120N, is convenient to transport and can be quickly disintegrated in 30 seconds in the oral cavity.
