Adefovir dipivoxil, previously called bis-POM PMEA, with trade names Preveon® and Hepsera®, is an orally-administered nucleotide analog reverse transcriptase inhibitor (ntRTI) used for treatment of Hepatitis B. It is a failed treatment for HIV.
Gilead Sciences discontinued its development for HIV treatment in December 1999 but continued to develop the drug for Hepatitis B (HBV), where it is effective with a much lower dose. FDA approval for use in the treatment of Hepatitis B was granted on September 20, 2002, and adefovir is sold for this indication under the brand name Hepsera.
