What is Tavin-EM (Tenofovir Disoproxil Fumarate/Emtricitabine) used for?

Tavin-EM contains two ingredients, that when used with a another anti-retroviral tablets can help to treat HIV infection or be used for PrEP (pre-exposure prophylaxis) to reduce the risk of contracting HIV. Tavin-EM is classifed as a nucleoside analog reverse transcriptase inhibitor (NRTI). It contains the active ingredients emtricitabine and tenofovir disoproxil fumarate combined in one tablet.

HIV infects CD4 cells (also called T cells) in the body. These cells are important in fighting infection. Once HIV is contracted, the virus multiplies inside these cells and the subsequent viruses are then released into the blood and infect other CD4 cells.

Tavin-EM works by inhibiting viral-specific enzyme reverse transcriptase (RT), which hinders the replication of the HIV-1 virus and results in a lower viral load (decreased amount of HIV virus in the blood). In some cases Tavin-EM can increase the number of CD4 cells in the body.

Tavin-EM can be used as a treatment in two different situations:

• treating patients who have already contracted HIV
• PrEP (pre-exposure prophylaxis) to reduce the risk of contracting HIV
