Problems solved by technology

The main ingredient of Cilibenan Tablets is silybin meglumine, but it still has the disadvantage of low bioavailability
The main ingredient of Shuilinjia is silybin lecithin complex, although the bioavailability has been improved to a certain extent by improving the fat solubility, but its water solubility is still poor

Abstract

The invention discloses a medical complex containing silybin di-partial succinate, a preparation method and an application thereof. The silybin di-partial succinate and phospholipid are dissolved in an organic solvent based on a certain ratio, drying and concentration are carried out after heating and refluxing, and the product is obtained. The complex not only enhances the solubility of silybin but also enhances the lipid solubility and obviously improves the problem of low bioavailability. The complex has the effect of protecting a liver and can be used in the therapy of acute and chronic hepatitis, fatty liver and other liver dysfunctions.

Description

technical field [0001] The invention belongs to the field of medicine, and in particular relates to a phospholipid complex containing the active ingredient silybin dimesuccinate. The specific feature of the complex is that it can obviously improve its fat solubility and improve its bioavailability while increasing its water solubility. , to play a better curative effect in protecting the liver. Background technique [0002] In recent years, with the improvement of people's living standards and changes in dietary structure, the incidence of fatty liver in my country has approached the carrier rate of hepatitis B virus, and it is showing a clear upward trend. Among them, men aged 30 to 40 are the "main force" in the army of fatty liver patients, basically accounting for 1 / 4 of all fatty liver patients. It is estimated that the incidence of fatty liver is now about 30 times higher than that before the 1980s. It is reported that 15% of patients with fatty liver will develop ci...
