Abstract

The invention relates to a butyl phthalide tablet and a preparation method thereof. The butyl phthalide tablet is composed of butyl phthalide solid powders and other medical troche auxiliary materials; wherein, the butyl phthalide solid powders are composed of the components with the following weight percentage: 9 percent to 30 percent of butyl phthalide, 0.01 percent to 1.2 percent of emulsifiers and 70 percent to 90 percent of cyclodextrin or cyclodextrin ramification. The troche which is made with the invention has favorable forming, stable product quality and high dissolution rate.

Description

technical field [0001] The invention relates to a butylphthalide tablet and a preparation method thereof. Background technique [0002] Racemic butylphthalide (dl-3-n-butylphthalide) and its two enantiomers developed in later stage: D-butylphthalide (d-3-n-butylphthalide), L-butylphthalide (1-3 -n-butylphthalide) all three are a kind of volatile oil which is insoluble in water. [0003] Because the volatile oil is easy to volatilize at room temperature, it is easy to volatilize and lose during the conventional preparation process, so it is difficult to effectively control the content, and the migration of active ingredients can easily cause uneven content, and it is easy to have stains or oil leakage during tablet compression, making it difficult to control the content. Preparation of stable and high oil content formulations. Therefore, a series of explorations have been carried out for the preparation technology of butylphthalide. [0004] As early as CN93117148.2 (Examp...
