Embodiment 1

[0028] Prescription: silymarin (calculated as silybin) 7.7g

[0029] Polyethylene glycol 6000 37.3g

[0030] Make 1000 capsules

[0031] Option One

[0032] (1) Heat and melt the prescribed amount of polyethylene glycol 6000 at 80-90°C, and keep stirring at a low speed (10-20r / min). Spray the prescribed amount of silymarin powder that has been ultrafinely pulverized and passed through a 250-mesh sieve. The powder spraying process should be such that the sprayed silymarin powder is evenly sprinkled into the melt to form a uniform eutectic. (2) Raise the temperature of the material to 120°C-130°C, and increase the speed of the mixer to 120-150 rpm for high-speed shearing and stirring for 5-10s until uniform. (3) Reduce the stirring speed to 10-20r / min, and continue to stir for 20-30 minutes to gradually reduce the temperature of the eutectic to 80-90°C. (4) When the temperature of the condensing agent simethicone oil in the dropper of the dropping pill machine an...

experiment example 1

[0050] This experimental example is to study the preparation process of each step of the present invention.

[0051] (1) The influence of the choice of matrix on the drop pills

[0052] In embodiment 1 and comparative example 1 and 2, the dropping pills of different substrates prepared according to the method of the present invention are compared, and the comparison results are shown in Table 1

[0053] Forming comparison of different matrix dropping pills in table 1

[0054]

[0055] It can be seen from the experimental comparison results that the present invention uses polyethylene glycol 6000 as the matrix.

[0056] (2) The influence of the selection of the screen on the dripping pills

[0057] Due to the particularity of the drop pill dosage form, the raw material silymarin needs to be micronized to be evenly dispersed in the matrix. The method of micropowder comprises mechanical pulverization and micropowder crystallization, and what the present invention adopts is ...

Embodiment 2

[0071] This experimental example investigates the dissolution rate of the drop pills made by the preparation process of the present invention, and compares it with the prior art.

[0072] The determination of the dissolution rate of the present invention is based on the 2010 edition of the Chinese Pharmacopoeia Part Two Appendix X C dissolution test method, using artificial gastric juice as the dissolution medium for determination. Wherein the identification amount of dissolution rate is 70%.

[0073] The present invention compares the dissolution rate between commercially available Yiganling tablets, capsules and prior art CN1775208A, CN1490001A drop pills, and compares the dissolution rate of each dosage form within 45min, and the comparison results are as follows:

[0074] The data of table 5 drop pill dissolution rate

[0075]

[0076] The comparison shows that the material ratio and the preparation process adopted in the present invention improve the dissolution r...

Abstract

The invention discloses a silymarin compound and a pharmaceutical composition containing an extract thereof. Polyethylene glycol 2,000-8,000 is adopted as an excipient, and thus the content of silymarin in combined medicines is increased by selecting a proper proportion; meanwhile, the polyethylene glycol 2,000-8,000 plays a key role in key technologies of preparation, dropping preparation and the like of the product, the preparation time is shortened, and the product yield is increased.

Description

technical field [0001] The invention relates to a silymarin compound, a pharmaceutical composition containing the extract, and a preparation method of the pharmaceutical composition. Background technique [0002] Silymarin is a light yellow to light brown loose powder. Silymarin is an antioxidant derived from a plant called Milk Thistle. Silymarin can stabilize liver cell membranes, maintain the integrity of liver cells, prevent toxins from penetrating and destroying the liver, and accelerate the synthesis of DNA (deoxyribonucleic acid) in liver cells, which can prevent liver cirrhosis, fatty liver, cholangitis, psoriasis and other diseases , while inhibiting the growth and differentiation of liver cancer, prostate cancer, breast cancer and cervical cancer cells. It is the flavonoid with the most curative effect on liver disease found in the world. [0003] Although silymarin has a significant effect as a liver-protecting drug, there are many problems in clinical applicat...
