Abstract

The invention belongs to the technical field of medicines, and in particular relates to an anhydroicaritin tablet. The anhydroicaritin tablet contains anhydroicaritin, hydroxy propyl cellulose, fumed silica, diethylene glycol monoethyl ether and other pharmaceutically acceptable auxiliary materials. A preparation method comprises the following steps: dissolving anhydroicaritin and hydroxy propyl cellulose in diethylene glycol monoethyl ether, adding with fumed silica for adsorption, then uniformly mixing with the pharmaceutically acceptable auxiliary materials, and carrying out pressing by adopting a direct tableting technology. The medicine dissolution speed is high, the process is simple, a surfactant does not need to be added, and the micronization treatment is not needed. The acceleration test result shows that the prepared anhydroicaritin tablet is good in stability.

Description

technical field [0001] The invention belongs to the technical field of medicine, and in particular relates to an icarigenin tablet. Background technique [0002] Icaritin (IT) is a polyhydroxy flavonoid monomer component in Epimedium genus Epimedium of Berberidaceae, and its structural formula is as follows: [0003] [0004] Pharmacological studies have shown that the anti-osteoporosis activity of IT is stronger than that of other flavonoid glycosides in Epimedium, and it can promote the activity of osteoblasts and inhibit the activity of osteoclasts in vitro. Icariin, as one of its main active ingredients, has attracted the attention of many scholars at home and abroad in recent years, and has conducted in-depth and extensive research on its pharmacological effects. The results so far have found that the main physiological activity of icariin lies in improving Cardiovascular and cerebrovascular system functions, enhance the body's immunity and regulate endocrine, and a...
