Lamivudine

Lamivudine is an antiviral medicine used to treat HIV (human immunodeficiency virus) and hepatitis B virus (HBV) infections. It belongs to a class of drugs called nucleoside reverse transcriptase inhibitors (NRTIs). Lamivudine works by blocking the activity of reverse transcriptase, an enzyme used by the viruses to replicate their genetic material. This prevents the viruses from multiplying and can reduce the amount of virus in the body. Lamivudine is usually used in combination with other medications to treat HIV and HBV infections. It can also be used to prevent HBV infection in people who are exposed to the virus.
