Embodiment 1

[0037] One, the preparation of osthole inclusion compound:

[0038] Weigh 0.244 g of osthole, dissolve it in 20 mL of absolute ethanol, heat to 50°C, and stir to completely dissolve to obtain solution A;

[0039] Weigh 1.135 g of β-CD, place in 30 mL of distilled water, heat and stir until completely dissolved to obtain solution B;

[0040] Divide solution B into two parts on average, and add them to solution A in turn, with an interval of 15 minutes between the two additions; 6 hours later, the above mixed solution is rotary evaporated to remove ethanol, and concentrated to about 30 mL;

[0041] Refrigerate at a temperature of 4°C for 12 hours to obtain a white suspension, which was suction-filtered, and the precipitate was quickly washed with 50 mL of ethanol and appropriate amount of distilled water in turn, and vacuum-dried at 40°C to obtain a crude clathrate product, which was pulverized and passed through 80 Mesh sieve to obtain osthole inclusion compound.

[0042] Two...

Embodiment 2

[0061] The osthole β-cyclodextrin inclusion compound was prepared according to the technical scheme of Example 1.

[0062] Prepare the osthole inclusion compound dispersible tablet with the following components and ratios by weight:

[0063] Osthole β-cyclodextrin inclusion complex 72.5%

[0064] Thinner Microcrystalline Cellulose MCC 5%

[0065] Disintegrant cross-linked polyvinylpyrrolidone PVPP 16%

[0066] Disintegrant Low-substituted hydroxypropyl cellulose LPC 4%

[0067] Suspension micronized silica gel 1.5%

[0068] Lubricant Talc 1%

[0069] According to the preparation method of the osthole inclusion compound dispersible tablet of Example 1, after the disintegrating agent, diluent, suspending agent, corrective agent and the osthole inclusion compound are mixed uniformly by an equal amount incremental method, then add The glidant and lubricant are mixed evenly and tabletted to obtain osthole inclusion compound dispersible tablets.

Embodiment 3

[0071] The osthole β-cyclodextrin inclusion compound was prepared according to the technical scheme of Example 1.

[0072] Prepare the osthole inclusion compound dispersible tablet with the following components and ratios by weight:

[0073] Osthole β-cyclodextrin inclusion complex 60%

[0074] Thinner Microcrystalline Cellulose MCC 15%

[0075] Disintegrant cross-linked polyvinylpyrrolidone PVPP 16%

[0076] Disintegrant Low-substituted hydroxypropyl cellulose LPC 6%

[0077] Suspension micronized silica gel 2%

[0078] Lubricant Magnesium Stearate 1%

[0079] According to the preparation method of the osthole inclusion compound dispersible tablet of Example 1, after the disintegrating agent, diluent, suspending agent, corrective agent and the osthole inclusion compound are mixed uniformly by an equal amount incremental method, then add The glidant and lubricant are mixed evenly and tabletted to obtain osthole inclusion compound dispersible tablets.

Abstract

The invention discloses a soluble osthole clathrate, a dispersing tablet and a preparation method thereof. Beta-cyclodextrin (beta-CD) is adopted as a carrier to prepare the osthole-beta-cyclodextrin clathrate (Ost-beta-CD), thus greatly raising the solubility and stability of osthole and reducing the irritation to gastrointestinal tract; simultaneously, by the selection of high-quality auxiliary materials, an osthole clathrate dispersing tablet which disintegrates rapidly and disperses uniformly is provided. The dispersing tablet can be swallowed and chewed, and can also be taken in dosages after being put into water and dispersed uniformly, especially suitable for elders, children and patients who have difficulty in swallowing solids. A preparation technology provided by the invention is adopted to raise the bioavailability of the hardly soluble medicament osthole and improve the curative effect of the medicament.

Description

technical field [0001] The invention relates to a technology for improving the osthole extracted from traditional Chinese medicine to improve the curative effect, in particular to an osthole inclusion compound, a dispersible tablet and a preparation method thereof, belonging to the technical field of medicine preparation. Background technique [0002] Osthole, also known as methoxyparscreol (Osthol, Ost), is a coumarin compound extracted from the fruit of the plant Cnidium of the Umbelliferae family Cnidium, and its chemical name is 7-methoxy -8-prenyl coumarin (7-methoxy-8-[3-methylpent-2-eny1]coumarin). Since the 1980s, research on osthole at home and abroad has become increasingly extensive and in-depth. Modern pharmacological experiments have shown that Ost not only has important effects on the cardiovascular system, central nervous system, and immune system, but also has anti-tumor, anti- Osteoporosis and anti-allergic aspects also have strong effects. With the in-de...
