Entecavir is a new generation of oral guanosine analogs for the treatment of hepatitis B virus infection. It is mainly used for the treatment of chronic hepatitis B with active viral replication and persistently elevated serum transaminases, or active liver histology in adults. Hepatitis is currently the fastest and strongest nucleoside analog for virus reduction and the lowest mutation probability. The data show that: different chronic hepatitis B patients, including nucleoside-naïve, nucleoside-experienced and liver cirrhosis patients, can quickly control the disease by using entecavir tablets, and easily reach the realistic endpoint of treatment, that is, hepatitis B virus is undetectable; After treatment, a considerable number of patients can reach the satisfactory end point of treatment, that is, e-antigen seroconversion, and some patients can even reach the ideal end point of treatment, that is, surface antigen negative conversion.

Adefovir dipivoxil is an oral broad-spectrum antiviral drug, originally synthesized by Gilead in the United States, and approved by the FDA in September 2002 for listing in the United States. It is also another oral anti-HBV drug after lamivudine. The American Association for the Study of Liver Diseases, the Asia-Pacific Society for the Study of the Liver, and China's "Guidelines for the Prevention and Treatment of Chronic Hepatitis B" recommend adefovir dipivoxil as the first-line choice for newly treated patients. Adefovir dipivoxil can inhibit the activity of HBV DNA polymerase, and can penetrate into the DNA of hepatitis B virus, inhibit the replication of the virus, and has a strong inhibitory effect on HBV virus strains resistant to lamivudine and famciclovir. for the treatment of hepatitis.
