Lamivudine is a nucleoside antiviral drug. It has a strong inhibitory effect on hepatitis B virus (HBV) in vitro and in experimentally infected animals. Lamivudine can be metabolized in HBV-infected cells and normal cells to produce lamivudine triphosphate, which is the active form of lamivudine and is both an inhibitor of HBV polymerase and a substrate of this polymerase. Lamivudine triphosphate penetrates into the viral DNA chain and blocks the synthesis of viral DNA. Lamivudine triphosphate does not interfere with the metabolism of deoxynucleosides in normal cells. It has a weak inhibitory effect on mammalian DNA polymerase a and b and has almost no effect on the DNA content of mammalian cells. Lamivudine has no obvious toxicity to the structure, DNA content and function of mitochondria. The results of serum HBVDNA detection in most hepatitis B patients showed that lamivudine can rapidly inhibit HBV replication, and its inhibitory effect lasts throughout the treatment process, while reducing serum aminotransferase to normal.
