Abstract

The invention discloses Huangyangning dispersible tablets and a preparation method thereof. Raw materials are subjected to nanocrystallization with a supercritical fluid method, then Cyclovirobuxine D, soybean lecithin, PEG4000, microcrystalline cellulose, hydroxypropyl cellulose, aerosil and aspartame are granulated with an equivalent incremental method by use of 60% ethyl alcohol, and drying and tableting are performed. Compared with Huangyangning on the market, the dispersible tablets have characteristics of high solubility and dissolution rate, quick absorption, high bioavailability and the like; the quality of the dispersible tablets can be better improved and development of drugs is facilitated.

Description

technical field [0001] The invention belongs to a huangyangning dispersible tablet and a preparation method thereof, and belongs to the field of pharmaceutical preparations. Background technique [0002] Buyangning Dispersible Tablets are processed from Cycloviral Buxus D as the active ingredient and excipients. [0003] Extracted and refined from poplar plant Euonymus microphylla and its genus, molecular formula C26H46N2O, molecular weight: 402.66, structural formula as follows: [0004] [0005] The currently commercially available Buxusine dispersible tablets mainly use cyclovirboxic star D with a larger particle size, microcrystalline cellulose, pregelatinized starch and other auxiliary materials for conventional granulation and tabletting. The existing disadvantages mainly include: [0006] (1) The particle size of Cyclovitamin D used is relatively large, the uniformity of granulation is poor, the solubility and solubility are poor, and the bioavailability will be ...
