Brand Name: Atripla
Generic Name: Efavirenz, emtricitabine, tenofovir disoproxil fumarate, EFV/FTC/TDF
Atripla is a combination drug that contains 600 milligrams of efavirenz (Sustiva), 200 milligrams of emtricitabine (Emtriva), and 300 milligrams of tenofovir disoproxil fumarate (Viread). It is prescribed for the treatment of HIV.
Read the FDA description of Atripla.
Two components of Atripla are emtricitabine and tenofovir disoproxil fumarate. These medications are nucleoside reverse transcriptase inhibitors (NRTIs). They block the effectiveness of the reverse transcriptase enzyme, which HIV needs to replicate in the body. Efavirenz is the third Atripla component. It is a non-nucleoside transcriptase inhibitor (NNRTI). It also reduces the ability of HIV to replicate in the body.
Atripla is not a cure for HIV. It is meant to slow the progression of the virus. You can take this medication on an empty stomach. Taking the medication at night can help to minimize side effects (FDA, 2008).
