Key Uses and Functions : Chronic Hepatitis B Treatment: It manages long-term HBV infection in patients with both compensated and decompensated liver disease. Virus Suppression: It inhibits the viral DNA polymerase enzyme, stopping the virus from multiplying in liver cells. Liver Protection: By reducing viral load, it helps prevent further liver damage.

Prevents HBV from multiplying inside liver cells, allowing the immune system to control infection
