Problems solved by technology

However, due to the steroid-like effect of glycyrrhizic acid, there are serious adverse reactions such as water and sodium retention, high blood pressure and hypokalemia after long-term administration, and oral administration is easy to form micelles in the intestinal tract, resulting in malabsorption and low bioavailability
The clinical efficacy of matrine drugs is not good, and they have been used for the treatment of hepatitis B for a long time, and have gastrointestinal irritation
There are clinical reports that the combined application of diammonium glycyrrhizinate capsules and matrine injection has achieved good curative effect in the treatment of chronic hepatitis B, but this method has not completely solved the problem of poor absorption of oral preparations of glycyrrhizinate, excessive side effects, and excessive dosage of combined drugs. The problem of inconvenient use for large patients

The invention also provides the use of the pharmaceutical composition in treating acute and chronic hepatitis and related diseases. the invention also provides various dosage forms of the pharmaceutical composition.

Description

technical field [0001] The invention belongs to the field of medicine. It relates to a pharmaceutical composition and its use. The pharmaceutical composition contains isoglycyrrhizic acid and matrine or their derivatives. And the application of the pharmaceutical composition in preventing and treating human hepatitis or hepatitis-related diseases or tumors. Background technique [0002] Liver disease, especially viral hepatitis, is a common and frequently-occurring disease in my country. At present, there is no drug with ideal therapeutic effect on it. Clinically, antiviral drugs are often used for treatment, and liver-protecting drugs are added to improve the curative effect. However, due to the inaccurate therapeutic effect and strong clinical side effects of such drugs, the prognosis is often unsatisfactory. [0003] Both glycyrrhizic acid and matrine have certain anti-hepatitis virus and liver protection effects, and similar products of the two have been used in the...
