Problems solved by technology

[0007] Ginkgolide B is insoluble in water and has poor stability. The existing preparations are mainly injections, which are inconvenient to use. The oral preparations show the characteristics of poor absorption in the body after research. Because Ginkgolide B is expensive, the bioavailability is not high, and the absorption is not good. It will cause great waste. In order to improve the efficacy, the present invention proposes an effective solution to improve the bioavailability, which solves the problem of absorption and utilization of the product.

Abstract

The present invention relates to a bilobalide B dripping pills preparation and its preparation method. It is formed from effective component bilobalide B and matrix for making dripping pills. The weight ratio of bilobalide B and matrix is 1:1.5-9.

Description

Technical field: [0001] The invention relates to the field of pharmaceutical preparations, in particular to a ginkgolide B drop pill extracted from ginkgo biloba leaves and a preparation method thereof. Background technique: [0002] Ginkgolide (ginkgolide) is one of the main active ingredients of Ginkgo biloba. In 1932, Furukawa isolated terpene lactones from Ginkgo biloba leaves for the first time. In 1967, Maruyama et al. isolated ginkgolides A, B, C and M from the root bark of Ginkgo biloba and determined their chemical structures. In 1987, Weinges isolated ginkgolide J from Ginkgo biloba leaves. Ginkgolide molecule has a unique twelve-carbon skeleton structure, embedded with a tert-butyl group and six five-membered rings, including a spiro[4,4]nonane, a tetrahydrofuran ring and three lactone rings. Ginkgolides A, B, C, M and J are represented by codes BN52020, BN52021, BN52022, BN52023 and BN52024 respectively, wherein the content of BN52021 in Ginkgo biloba is 0.2%....
