Interaction Details
Etravirine is classified as belonging to the following category: Cytochrome P450 3A4 (Cyp3A4) Substrates
Theoretically, beet might increase the levels of CYP3A4 substrates.
In vitro research suggests that betanin, the major pigment in beet, competitively inhibits CYP3A4 in a dose-dependent manner similarly to strong CYP3A4 inhibitor ketoconazole.

Beet Overview
Beetroot is a type of root vegetable belonging to the Chenopodiaceae family. It is commonly consumed as a food and utilized as a dietary supplement. Beetroot supplements are purported to have a number of potential health benefits, including lowering blood pressure by increasing the production of nitric oxide, improving exercise performance, and reducing inflammation.
Dietary supplements containing beetroot are generally in powdered form, and are sometimes standardized by their nitrate content.
Etravirine Overview
-
Etravirine is used along with other medications to treat human immunodeficiency virus (HIV) infection in adults and children 2 years of age and older who no longer benefit from taking other HIV medications. Etravirine is in a class of medications called non-nucleoside reverse transcriptase inhibitors (NNRTIs). It works by decreasing the amount of HIV in the blood. Although etravirine does not cure HIV, it may decrease your chance of developing acquired immunodeficiency syndrome (AIDS) and HIV-related illnesses such as serious infections or cancer. Taking these medications along with practicing safer sex and making other lifestyle changes may decrease the risk of transmitting (spreading) the HIV virus to other people.
