In Vitro Studies to elucidate the mechanism of action of Adefovir against herpesvirus replication reveals that the phosphorylation of Adefovir occurred intracellularly and is carried out by host cellular enzymes. The diphosphorylated derivatives of Adefovir targeted the viral DNA polymerase and also acted as DNA chain terminators. Adenylate kinase is shown to be responsible for the first phosphorylation, which was followed by ADP kinase and creatine kinase, forming Adefovir diphosphate[1].
In Vivo Unaffected by food, Adefovir achieves 60% oral bioavailability. Its half-life is 12-30 hours and Adefovir undergoes renal excretion without significant metabolites. Adefovir does not substantially affect the cytochrome P450 system[3].
