Embodiment 1

[0025] A sublingual tablet of total ginkgo flavonoids, which is made from 50 g of total ginkgo flavonoids, 90 g of pregelatinized starch, 25 g of microcrystalline cellulose, and 3 g of magnesium stearate; Cortexin 40%, isorhamnetin 35%, kaempferol 25%.

[0026] The specific preparation method is as follows: dry, pulverize, and sieve the above-mentioned main drug total flavonoids of ginkgo biloba, pregelatinized starch, microcrystalline cellulose and magnesium stearate; Debonding agent, use pure water and ethanol as binder to make the mixed material into soft material, granulate with 40 mesh sieve; and dry at 60°C until the moisture content is ≤3%; then add the lubricant The dry granules obtained above are mixed together, and finally compressed into tablets to obtain sublingual tablets of ginkgo total flavonoids.

[0027] The total ginkgo flavonoids sublingual tablet prepared in this example has a disintegration time of 2min25s.

Embodiment 2

[0029] A kind of ginkgo total flavonoids sublingual tablet, it is made of ginkgo total flavonoids 50g, alginic acid 56g, microcrystalline cellulose-mannitol 55g, thaumatin 1.5g, pine mucilage 2.5g, stearic acid 1.5g, talcum powder 1g Made; the ginkgolide contains the following components in mass fraction: 45% isorhamnetin, 20% quercetin, 35% kaempferol.

[0030] The specific preparation method is as follows: the above-mentioned components are pretreated by drying, pulverizing and sieving; after mixing evenly, they are directly compressed into tablets to obtain sublingual tablets of ginkgo total flavonoids.

[0031] The total ginkgo flavonoids sublingual tablet prepared in this example has a disintegration time of 2min28s.

Embodiment 3

[0033] A kind of ginkgo total flavonoids sublingual tablet, it is made of ginkgo total flavonoids 80g, gelatin 35g, microcrystalline cellulose 55g, xylitol 2.5g, cocklebur powder 11g, polyethylene glycol 4000 2.5g, polyethylene glycol 6000 1.5 g, the ginkgolide contains the following components in mass fraction: 40% quercetin, 15% kaempferol, and 45% isorhamnetin.

[0034] The specific preparation method is as follows: the above-mentioned components are dried, pulverized, and sieved for pretreatment; then the components except polyethylene glycol 6000 and polyethylene glycol 4000 are mixed evenly, and the dry granulator is used to make 40-mesh The granules are then added with polyethylene glycol 6000 and polyethylene glycol 4000, and compressed into tablets to obtain sublingual tablets of ginkgo total flavonoids.

[0035] The total ginkgo flavonoids sublingual tablet prepared in this example has a disintegration time of 2min17s.

Abstract

The invention discloses a gingko general flavone sublingual tablet and a preparation method thereof.The sublingual tablet is prepared from, by weight, 1-260 parts of gingko general flavone, 2-25 parts of disintegrating agent and 35-245 parts of filler.Gingko general flavone is prepared from, by weight, 35-50% of quercetin, 6-16% of kaempferide and 15-25% of isorhamnetin.The gingko general flavone sublingual tablet is prepared by organically combining disintegrating agent with filler, and the tablet is put under a tongue when taken and can be rapidly disintegrated and absorbed by sublingual mucosal and directly enter blood circulation through jugular veins and superior vena cava to rapidly act so as to rapidly relieve migraine symptoms.Meanwhile, the tablet is particularly suitable for the aged and other patients having difficulty in swallowing and patients having difficulty in taking water in special environments such as battlefields, outdoor environments and tourist environments.
