Atripla
Atripla is a combination antiretroviral therapy (ART) used to treat HIV-1 infection in adults. It is a single-tablet regimen containing three medications: efavirenz, emtricitabine, and tenofovir disoproxil fumarate.
Composition and Active Ingredients
Atripla contains three active ingredients that work together to suppress HIV replication:
- Efavirenz is a non-nucleoside reverse transcriptase inhibitor (NNRTI) that blocks the activity of HIV reverse transcriptase, an enzyme essential for the virus to replicate. Efavirenz prevents HIV from making copies of itself, thereby reducing the viral load in the body.
- Emtricitabine is a nucleoside reverse transcriptase inhibitor (NRTI) that works by inhibiting the activity of HIV reverse transcriptase. Emtricitabine interferes with the process of DNA synthesis by HIV, preventing the virus from replicating.
- Tenofovir disoproxil fumarate is another NRTI that also inhibits HIV reverse transcriptase. Tenofovir disoproxil fumarate works similarly to emtricitabine, blocking the formation of viral DNA and inhibiting HIV replication.
Mechanism of Action
Atripla’s mechanism of action relies on the combined effects of its three active ingredients. The NNRTI, efavirenz, directly binds to HIV reverse transcriptase, altering its structure and inhibiting its activity. The two NRTIs, emtricitabine and tenofovir disoproxil fumarate, act as nucleoside analogs, which are molecules that resemble natural building blocks of DNA. These analogs are incorporated into the viral DNA chain during replication, ultimately terminating the process and preventing the production of new viral particles.
Pharmaceutical Formulation
Atripla is available as a single-tablet formulation for oral administration. Each tablet contains 600 mg of efavirenz, 200 mg of emtricitabine, and 300 mg of tenofovir disoproxil fumarate.
