Adefovir dipivoxil is an oral prodrug of adefovir, an acyclic nucleotide phosphonate analogue of adenosine monophosphate, which is actively transported into mammalian cells where it is converted by host enzymes to adefovir diphosphate. Adefovir diphosphate inhibits viral polymerases by competing for direct binding with the natural substrate (deoxyadenosine triphosphate) and, after incorporation into viral DNA, causes DNA chain termination.
Hepsera is supplied in high-density polyethylene (HDPE) bottles with a child-resistant closure. Each bottle contains 30 tablets, silica gel desiccant and fibre packing material.
