Problems solved by technology

Due to the poor water solubility of bicyclol, the dissolution rate of ordinary tablets in vitro is relatively slow. When distilled water is used as the dissolution medium, only 60% to 70% can be dissolved within two hours. There are more significant individual differences, which is not conducive to the exertion of its curative effect

Abstract

The invention discloses a phospholipids compound of bicyclo-ethanol and a preparation method thereof, in particular relates to a phospholipids compound of bicyclo-ethanol, a preparation method of the phospholipids compound of bicyclo-ethanol and a preparation containing the phospholipids compound of bicyclo-ethanol. The phospholipids compound of bicyclo-ethanol comprises bicyclo-ethanol and phospholipids material with the weight proportion of 1 to 2-12. The phospholipids compound can be selectively added with antioxidative stabilizer and / or srobent. In the invention, bicyclo-ethanol is prepared into the phospholipids compound so that the water-dispersible property and the lipotropy of the bicyclo-ethanol are both improved. Compared with the raw material medicine of the bicyclo-ethanol, the phospholipids compound of bicyclo-ethanol can remarkably improve the blood concentration after being orally taken, and has higher biological validity when used for clinic treatment for chronic hepatitis.

Description

technical field [0001] The invention relates to a bicyclic alcohol phospholipid complex, which is composed of bicyclic alcohol and phospholipid materials, with a weight ratio of 1:2-12; the phospholipid complex can also optionally add antioxidant stabilizers and / or adsorbents . The invention also relates to a preparation method of the bicyclic alcohol phospholipid complex and a preparation containing the bicyclic alcohol phospholipid complex, belonging to the technical field of medicine. Background technique [0002] Bicyclol is an innovative anti-chronic hepatitis drug with independent intellectual property rights developed by the Institute of Materia Medica, Chinese Academy of Medical Sciences. Bicyclol has poor water-solubility and fat-solubility, and its bioavailability after oral administration is low, with significant individual differences. [0003] Bicyclol is a new anti-hepatitis drug developed by the Institute of Medicine, Chinese Academy of Medical Sciences. At ...
