How Lamivudine + Tenofovir Disoproxil Fumarate works
Lamivudine + Tenofovir Disoproxil Fumarate works by blocking the process the HIV and hepatitis B viruses use to multiply.
Lamivudine is a nucleoside reverse transcriptase inhibitor (NRTI). It mimics a natural building block of DNA. When the virus tries to copy its genetic material, lamivudine gets incorporated instead, which stops the DNA chain from growing further.
Tenofovir Disoproxil Fumarate is also an NRTI. It mimics a different DNA building block and works in a similar way, halting the growing DNA chain when the virus tries to replicate.
Together, the two medicines work in harmony to reduce the ability of the virus to multiply, helping manage HIV-1 and hepatitis B infections.
