Epivir-HBV Indication:

For the treatment of HIV infection and chronic hepatitis B (HBV).

Epivir-HBV Mechanism Of Action:

Epivir-HBV is a synthetic nucleoside analogue and is phosphorylated intracellularly to its active 5'-triphosphate metabolite, lamivudine triphosphate (L-TP). This nucleoside analogue is incorporated into viral DNA by HIV reverse transcriptase and HBV polymerase, resulting in DNA chain termination.

Epivir-HBV Drug Interactions:

Zalcitabine Epivir-HBV decreases the efficacy of zalcitabine

Epivir-HBV Food Interactions:

Take without regard to meals. Food does not decrease the extent of absorption, but it decreases the Cmax by slowing the rate of absorption.
