Description
Curator's Comment: description was created based on several sources, including: http://adisinsight.springer.com/drugs/800004771

Amdoxovir is a guanosine analogue nucleoside reverse transcriptase inhibitor that is active in vitro against both HIV-1 and HBV. It is deaminated intracellularly by adenosine deaminase to dioxolane guanine (DXG). DXG-triphosphate, the active form of the drug, has greater activity than DAPD-triphosphate. Amdoxovir is under development (phase II study) for the treatment of HIV infection. Five subjects demonstrated lens opacities during the study, although baseline evaluations were not performed. Clinical studies of amdoxovir are currently on hold pending additional safety data.
