Embodiment 1

[0039] A kind of ginkgo leaf capsule raw material formula of the present invention:

[0040] Ginkgo biloba extract 40g, β-cyclodextrin 150g, talcum powder 9g, magnesium stearate 1.0g.

[0041] The preparation method is as follows:

[0042] 1. Ingredients: Take 95% ethanol and prepare 25% ethanol, add 150g of β-cyclodextrin into it and stir well, so that the weight ratio of β-cyclodextrin and ethanol reaches 1:10, and obtain granulation spray grout.

[0043]2. Granulation: Put 40g of ginkgo leaf extract and 9g of talcum powder together in the hopper of the boiling granulation dryer, turn it on and mix well, then send the β-cyclodextrin ethanol solution spray liquid obtained in step 1) into the boiling granulation dryer. The spraying device of the granulation dryer starts spraying and granulating, so that the boiling granulation and drying can be granulated in one step, and the particle rate can reach more than 80%.

Abstract

The invention provides a ginkgo leaf capsule. The ginkgo leaf capsule comprises, by weight, 30 to 50 parts of a ginkgo leaf extract, 120 to 180 parts of beta-cyclodextrin, 7 to 12 parts of talcum powder and 0.5 to 1.5 parts of magnesium stearate. A granule is prepared from the above-mentioned raw materials and then fills a hard capsule shell so as to prepare the ginkgo leaf capsule. The ginkgo leaf capsule prepared in the invention has more stable performance and a better clinical curative effect. The invention further provides a preparation method for the ginkgo leaf capsule. The method comprises the following steps: preparing spraying slurry from beta-cyclodextrin and ethanol; subjecting the raw materials to one-step drying and granulation by using a fluid bed granulating and drying machine; and filling the obtained granule to prepare the capsule. The method can overcome disadvantages of the prior art and substantially improves bioavailability, solubility and chemical and physical stability of a drug.

Description

technical field [0001] The invention relates to a pharmaceutical preparation, in particular to a ginkgo leaf capsule and a preparation method thereof. Background technique [0002] Ginkgo biloba is a kind of medicinal material with high medicinal value. It tastes slightly bitter and flat in nature. It can benefit the heart, promote blood circulation and relieve pain, and relieve asthma. Ginkgo biloba extract is an extract processed from Ginkgo biloba leaves. It is a light brown to brown powder with a slightly bitter taste. It has been included in the 2010 edition of "Chinese Pharmacopoeia" as a standardized product and can be used as a raw material for preparation Medicines in various dosage forms, such as ginkgo leaves, ginkgo leaf capsules, pellets or soft capsules containing ginkgo leaves, etc. [0003] Ginkgo biloba capsules in the prior art have a relatively stable formula, and its functions and indications are promoting blood circulation, removing blood stasis and dre...
