Abstract

The invention belongs to the field of medicine and particularly relates to an intelligent and novel medicine composition having anti-hepatitis B virus activity and a preparation method thereof.The medicine composition contains an enteric magnesium isoglycyrrhizinate sheet core and further contains other types of anti-hepatitis B virus medicine.To be specific, further improvement is made on the basis of the prior art, a dissolution layer is further added outside an enteric magnesium isoglycyrrhizinate coating layer, and unexpectedly, the magnesium isoglycyrrhizinate medicine composition high in dissolution rate and good in bioavailablity is obtained.Furthermore, the dissolution layer is sequentially wrapped by a medicine containing layer and a protection layer, so that a compound preparation is formed, the compound preparation is convenient to take, and patient compliance is greatly improved.

Description

technical field [0001] The invention belongs to the field of medicine, and specifically relates to an intelligent, novel pharmaceutical composition with anti-hepatitis B virus activity and a preparation method thereof. Viral drugs. Background technique [0002] Hepatitis B is an infectious disease caused by hepatitis B virus (HepatitisBvirus, HBV), mainly characterized by liver inflammatory lesions and causing multiple organ damage. About 2 billion people in the world have been infected or are currently infected with HBV, and 400 million of them are chronically infected with HBV. Drugs for clinical treatment of hepatitis B include interferon, nucleoside drugs (such as lamivudine, adefovir dipivoxil, telbivudine, entecavir, tenofovir dipivoxil, etc.), traditional Chinese medicine drugs (such as matrine, Diammonium glycyrrhizinate, magnesium isoglycyrrhizinate, etc.). Among them, magnesium isoglycyrrhizinate is a new generation of glycyrrhizic acid compounds developed in Ch...
