Drug Action & Clinical Application

Oxymatrine is an alkaloid extracted from Sophora Flavescens, which is mainly composed of oxymatrine and contains a small amount of oxidized saponin. Oxymatrine is the main active ingredient of ginseng in whitening. It has the functions of clearing away heat and dampness, diuretic detoxification, improving hepatitis symptoms, signs, yellowing and enzyme lowering. It can inhibit the replication of hepatitis B virus, induce endogenous interferon, protect liver cells, improve liver function, resist liver fibrosis, raise white blood cells and fight tumors. It is suitable for the treatment of chronic hepatitis B, as well as leukopenia caused by tumor radiotherapy, chemotherapy and other causes of leukopenia. This product is an antiviral drug developed and produced in China. It can induce interferon alpha in the body, which can make the serum HBeAg and/or HBV DNA of chronic hepatitis B patients turn negative, blood alanine aminotransferase decreases, clinical efficacy and Interferon is similar.

In animal experiments, rabbits with low white blood cells caused by normal rabbits and radiation exposure have obvious effects of increasing white blood cells; they also have protective effects against toxic liver damage caused by carbon tetrachloride and D-galactose. Mouse C leukopenia caused by C is also effective. Oxymatrine is the only recommended antiviral Chinese medicine for the "Guide to the Prevention and Treatment of Hepatitis B". It can effectively reduce the level of HBV DNA, and can improve various serum indicators of liver fibrosis. At the same time, it can regulate immunity and induce endogenous interferon.
