Problems solved by technology

[0011] Most traditional Chinese medicine dispersible tablets contain about 30-50% of the main drug. It is not easy to rely on the remaining drug adjuvants to ensure rapid disintegration in 3 minutes and maintain a considerable dissolution rate. In addition, most of the traditional Chinese medicine extracts Macromolecular substances such as pectin and polysaccharides adhere to the surface of traditional Chinese medicine dispersible tablets when they disintegrate, causing negative effects on drug disintegration and dissolution
[0012] To sum up...

Embodiment 1

[0053] The weight percentage of traditional Chinese medicine extract and auxiliary materials of Duanxueliu dispersible tablet: fine powder of Duanxueliu extract 20%, crospovidone 24%, sodium carboxymethyl starch 20%, microcrystalline cellulose 10%, lactose 20%, Polyvinylpyrrolidone 3%, Magnesium Stearate 3%.

[0054] Duanxueliu dispersible tablets are obtained according to the following specific steps: take Duanxueliu, cut into sections, decoct twice with water for 1.5 hours each time, combine the decoctions, filter, and concentrate the filtrate to a relative density of 1.15 (80°C), Add 1.7 times the amount of ethanol, stir well, let it stand for 24 hours, take the supernatant and concentrate it under reduced pressure to form a thick paste, dry it into a dry extract, and pulverize it to obtain a fine powder of the blood flow extract.

[0055] First pass the above-mentioned materials through a 100-mesh sieve, and mix the fine powder of the broken blood flow extract with the mix...

Embodiment 2

Abstract

A dispersing tablet of Herba clinopodii for treating functional metrorrhagia, menorrhagia, postpartum hemorrhage, hysteromyoma hemorrhage, nosebleed, purpura simplex, primary thrombocytopenic purpura, etc is prepared from Herba clinopodii and proper additives.

Description

technical field [0001] The invention relates to the technical field of Chinese patent medicine dispersible tablets, in particular to a dispersible tablet for cutting off blood flow. Background technique [0002] Dispersible tablets are a new drug dosage form developed in recent years. There are many dosage forms of Duanxueliu, which have the effect of cooling blood and stopping bleeding. For functional uterine bleeding, menorrhagia, postpartum hemorrhage, uterine fibroids, hematuria, hematochezia, hematemesis, hemoptysis, epistaxis, simple purpura, idiopathic thrombocytopenic purpura, etc. Duanxueliu, one of the original dosage forms, is a sugar-coated tablet that has been included in the Chinese Pharmacopoeia. Duanxueliu sugar-coated tablets have slow dissolution, poor absorption and low bioavailability. [0003] Compared with ordinary tablets, dispersible tablets require that the temperature of the disintegration medium is 20±1°C, the disintegration time limit is less th...
