Adefovir dipivoxil is the oral prodrug of adefovir, which is actively transported into mammalian cells, where it is converted by host enzymes to adefovir diphosphate. Adefovir diphosphate inhibits viral polymerase by competitively binding directly to natural substrates and subsequently by incorporation into viral DNA causing DNA strand termination. Adefovir diphosphate selectively inhibits HBV DNA polymerase at concentrations 12,700 and 10 times lower than those required for selective inhibition of human DNA polymerases. In active and inactive leukocytes, adefovir diphosphate has an intracellular half-life of 12 and 36 hours, respectively. After oral administration of Adefovir dipivoxil was converted to adefovir, 45% of the 10 mg oral dose was recovered in the urine within 24 hours. Adefovir is found in the urine.
