These include antiviral medications lamivudine, adefovir, tenofovir disoproxil, tenofovir alafenamide,
telbivudine, and Entecavir, and the two immune system modulators interferon alpha-2a
and PEGylated interferon alpha-2a.
Entecavir is new,
antiviral effect is also strong, if not treated with lamivudine, the possible resistance is the smallest, but it and lamivudine have cross resistance, if treated with lamivudine to take Entecavir produced resistance rate is much greater.
