Lamivudine + Tenofovir Disoproxil Fumarate

Introduction

Lamivudine + Tenofovir disoproxil fumarate is a combination antiretroviral medication used primarily to treat HIV (Human Immunodeficiency Virus) and chronic hepatitis B virus infections. This fixed-dose combination is part of highly active antiretroviral therapy (HAART), working to reduce the viral load in the body and slow the progression of disease. Both Lamivudine and Tenofovir belong to a class of drugs known as nucleoside/nucleotide reverse transcriptase inhibitors (NRTIs), which help prevent the virus from multiplying and spreading. This composition is widely recommended due to its efficacy, tolerability, and ease of use.

Uses of Lamivudine + Tenofovir disoproxil fumarate

• Treatment of HIV-1 infection in adults and adolescents
• Management of chronic hepatitis B infection
• Used as part of pre-exposure prophylaxis (PrEP) in HIV prevention (when combined with other medicines)

How Lamivudine + Tenofovir disoproxil fumarate works

This composition works by inhibiting the action of reverse transcriptase, an enzyme essential for viral replication in both HIV and hepatitis B viruses. Lamivudine and Tenofovir are incorporated into the viral DNA and block further synthesis, thereby reducing the virus’s ability to multiply and spread in the body.
