Scientific Name: Entecavir
Brand Name: Baraclude
Company Owner: Bristol myers squibb
Mechanism Of Action By competing with the natural substrate deoxyguanosine triphosphate, entecavir functionally inhibits all three activities of the HBV polymerase (reverse transcriptase, rt) : (1) base priming, (2) reverse transcription of the negative strand from the pregenomic messenger RNA, and (3) synthesis of the positive strand of HBV DNA. Upon activation by kinases, the drug can be incorporated into the DNA which has the ultimate effect of inhibiting the HBV polymerase activity.
Description of the Drug: Entecavir is a nucleoside analogue used in the treatment of chronic hepatitis B for patients with active viral replication, histological evidence of active disease, or persistent elevations in liver transaminases.
