Medication (see also Medication, below)
Currently, interferon alfa (IFN-a), lamivudine, telbivudine, adefovir, entecavir
, and tenofovir
are the main treatment drugs approved globally, although ongoing trials are investigating new types of medications, such as tenofovir disoproxil in combination with emtricitabine, clevudine (l-FMAU), and therapeutic vaccines. It appears that lamivudine and telbivudine are not recommended as first-line agents in the treatment of hepatitis B disease.
