Description
Technical Field
The invention relates to a preparation method of a Chinese medicinal preparation, namely artemisia capillaris tablet.
Background
Cholestatic liver diseases caused by various reasons belong to the category of jaundice in traditional Chinese medicine. Damp-heat accumulated in the middle energizer fumigates the liver and gallbladder, causing liver dysfunction and bile overflow, which is the basic etiology and pathogenesis. The location of the disease is mainly in the liver, gallbladder, spleen and stomach, and also in the kidney after a long period of disease. It is usually treated by clearing heat and promoting diuresis, promoting blood circulation by removing blood stasis, cooling blood, resolving phlegm, etc.
The currently common oral jaundice-removing medicines in clinic mainly comprise Yinzhihuang effervescent tablets (oral liquid), jaundice virgate wormwood granules and the like. YINZHIHUANG is herba Artemisiae Scopariae extract, fructus Gardeniae extract, baicalin, and flos Lonicerae extract, and HUANGHUAYINCHEN granule is prepared from herba Artemisiae Scopariae, Scutellariae radix, radix et rhizoma Rhei (preparata), and Glycyrrhrizae radix, and has effects of clearing heat, promoting diuresis, and eliminating jaundice. Can be used for treating acute and chronic infectious icterohepatitis. Both of them are not traditional classical formula, mainly have the main effects of clearing heat and removing toxicity, lack the effect of removing blood stasis, do not embody the action characteristics of traditional meridian formula, and limit the improvement of clinical curative effect of traditional Chinese medicine.
Aiming at the disease, the modern hospitals are lack of effective treatment medicines at present. The commonly used clinical S-adenosine-L-methionine (butanedisulfonic acid ademetionine) enteric-coated tablet and ursodeoxycholic acid, etc., the former can reduce bilirubin to a certain extent, but has no obvious effect on patients with mild increase of total bilirubin of chronic liver diseases and has high price. The latter is mainly characterized by the reduction of GGT and AKP, and the effect of reducing bilirubin is limited. The two medicines are obviously weaker than the traditional Chinese medicine in the aspects of improving the clinical symptoms of patients and relieving the pain of the patients.
The artemisia capillaris decoction is firstly recorded in Shang Han Lun of Zhang Zhongjing in the Han Dynasty, is a first-choice prescription for clinically treating yang-jaundice, and is advocated by past physicians. The original formula of the artemisia capillaris decoction comprises six to two artemisia capillaris, fourteen gardenias and two rhubarb. Clinical and experimental researches show that the artemisia capillaries soup has the effects of promoting bilirubin metabolism, resisting liver injury, inhibiting hepatocyte apoptosis, inhibiting stellate cell activation and collagen synthesis. Three models, namely a bile duct ligation model, a DMN model and the like, are used for verifying that the artemisia capillaris decoction has obvious functions of benefiting gallbladder, removing jaundice, reducing enzyme and protecting liver in the early stage of a subject group. However, the decoction is inconvenient to carry.

Example 5: formulation process investigation
(1) Selection of granulation Process
According to the combination of the preparation process characteristics of the tablets and the prescription amount, as the raw materials are all powder, the extract has larger specific gravity and the auxiliary material space amount is narrow, the granulation technology is selected to improve the material fluidity, so as to be beneficial to tabletting; compared with the wet granulation method and the dry granulation method, the mixed extract contains water-soluble components such as polysaccharide and the like, has larger hygroscopicity, and is easy to adhere to a screen mesh in the wet granulation process and difficult to form. Dry granulation was therefore selected with the addition of binder povidone K30. The result of comparison and investigation of the proportion of microcrystalline cellulose MCC as a filler and polyvinylpyrrolidone K30 as a binder in the auxiliary materials shows that the proportion of 75 to 25 percent can ensure that the material has better fluidity.

| Ratio of filler MCC to binder K30 | 50％︰50％ | 75％︰25％ | 100％︰0％ |
| Angle of repose | 41° | 47° | 37° |
(2) Selecting auxiliary materials: in order to enable the active component to have better bioavailability and better preparation characteristics, the investigation conditions such as the type and the dosage of the auxiliary materials are selected, and the type and the dosage of the auxiliary materials are investigated by taking the disintegration time limit of the tablet as an index. Finally, a proper amount of microcrystalline cellulose, 5 percent of polyvinylpyrrolidone K30 and 3 percent of low-substituted hydroxypropyl cellulose are selected as granulation auxiliary materials. Meanwhile, in order to ensure that the surface of the pressed tablet is smooth and avoid sticking, 1% of lubricant magnesium stearate is added after granulation for tabletting.
