Elvitegravir/cobicistat/emtricitabine/tenofovir, sold under the brand name Stribild, also known as the Quad pill, is a fixed-dose combination antiretroviral medication for the treatment of HIV/AIDS. Elvitegravir, emtricitabine and tenofovir disoproxil directly suppress viral reproduction. Cobicistat increases the effectiveness of the combination by inhibiting the liver and gut wall enzymes that metabolize elvitegravir. It is taken by mouth. It is manufactured by Gilead Sciences.

Serum creatinine (a marker of kidney function) may increase with use of elvitegravir/cobicistat/emtricitabine/tenofovir. This is caused by cobicistat's inhibition of tubular secretion in the nephron.
