Introduction to Lamivudine
Lamivudine is a well-recognized antiretroviral medication used predominantly in the treatment of HIV (Human Immunodeficiency Virus) and Hepatitis B. It belongs to a class of drugs known as nucleoside reverse transcriptase inhibitors (NRTIs), which block HIV replication and reduce the viral load in the body.
Medical Uses of Lamivudine
Lamivudine serves multiple therapeutic purposes, notably in the treatment of viral infections.
HIV Treatment
- Combination Therapy: Lamivudine is often combined with other antiretroviral drugs like Zidovudine for a potent effect.
