Description: Entecavir, abbreviated ETV, is an oral antiviral drug used in the treatment of hepatitis B infection. It is marketed under the trade names Baraclude (BMS), Entaco (Ranbaxy) and Entaliv (DRL).
Entecavir is a nucleoside analog[1] (more specifically, a guanosine analogue) that inhibits reverse transcription, DNA replication and transcription in the viral replication process.
