Emtricitabine/rilpivirine/tenofovir

Emtricitabine/rilpivirine/tenofovir, sold under the brand name Complera among others, is a fixed-dose combination of antiretroviral drugs for the treatment of HIV/AIDS.[4] The drug was co-developed by Gilead Sciences and Johnson & Johnson's Tibotec division and was approved by the US Food and Drug Administration (FDA) in August 2011, and by the European Medicines Agency in November 2011,[3][5] for patients who have not previously been treated for HIV.[6] It is available as a once-a-day single tablet.

In the European Union it is marketed as Eviplera and in the US as Complera.[7]
