Abstract

The invention discloses a Swerianmarin injection, its preparation process and application, wherein the preparing process comprises using Gentianaceae, Scrophulariaceae or Oleaceae plants as raw material, employing conventional phytochemical method for extraction, segregation and purification, thus obtaining swertiamarin, weighing swertiamarin and medicinal adjuvant, charging water for injection, thermal insulating 10-20 minutes at 30-60 deg. C, cooling down, filtering, dispensing the filter liquor 1-48 hours at 0-5 deg. C, filtering, encapsulating, drying in frozen, sterilizing, and packaging.

Description

technical field [0001] The invention relates to a pharmaceutical preparation and its preparation method and application. Background technique [0002] Hepatitis is a self-limiting disease. After getting the disease, provide appropriate treatment and rest. In most cases, the body will gain immunity and recover. However, in the acute stage of the disease attack or the acute stage of chronic hepatitis, improper treatment or other reasons lead to the deterioration or delay of the disease, which will make the virus resistant to the body's immune antibodies, avoid the body's clearance of the virus or slow down the clearance of the virus. Increase the incidence of chronic hepatitis, thereby leading to diseases such as liver cirrhosis and liver cancer, bringing life-long suffering to patients. Therefore, for hepatitis, especially viral hepatitis, early treatment is very critical and important. [0003] There are 28 million chronic hepatitis patients with he...
