tenofovir alafenamide cost

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.
The drug is manufactured by Gilead Sciences.
An increase in the serum creatinine level (a marker of kidney function) may increase with use of Elvitegravir/cobicistat/emtricitabine/tenofovir. This is caused by inhibition of tubular secretion of creatinine in the nephron by cobicistat. An increase of up to 0.3 mg/dL is expected; if serum creatinine level increases by 0.4 mg/dL or more, further evaluation for other causes of acute kidney injury is recommended.
