[Research progress on activities and mechanisms of anti-hepatitis B virus drugs].

ABSTRACT

Hepatitis B virus(HBV) is the pathogen causing hepatitis B, which is characterized by strong infectivity, high incidence, and widespread prevalence and has seriously threatened human health and affected their quality of life. Anti-HBV drugs in western medicine mainly include nucleosides(nucleic acids) and interferons, among which nucleosides(nucleic acids) are used more often. Due to the easy development of drug resistance, their therapeutic effects are not remarkable. Interferons can easily cause serious adverse reactions such as liver injury. Anti-HBV drugs in traditional Chinese medicine mainly include single Chinese herbs(Artemisiae Scopariae Herba, Artemisiae Annuae Herba, Salviae Miltiorrhizae Radix et Rhizoma, etc.) and Chinese herbal compounds(Yinchenhao Decoction, Xiaochaihu Decoction, Tiaogan Huaxian Pills, etc.), whose chemical compositions and action targets have not been fully identified. The combined medication is better than single medication, in that the former can improve drug resistance, make up each other's deficiencies, reduce adverse reactions, and prolong the action time. This study reviewed the anti-HBV activities and mechanisms of western drugs, Chinese herbs, and combined medications, in order to provide reference for the development and research of new anti-HBV drugs.
