Adefovir (Trade name: Preveon, Hepsera) is a prescription drug used
for the treatment of chronic infections of hepatitis B virus. It can
be formulated as the pivoxil prodrug adefovir dipivoxil. However, it
shows no effect against HIV-1. As a orally administrated acyclic
nucleotide analog reverse transcriptase inhibitor, it blocking the
reproduction of HBV through inhibiting the reverse transcriptase in
the body. One of its advantages over another anti-HBV drug,
lamivudine is that it is much harder for the virus to develop
resistance to it.
