The U.S. FDA has approved a new HIV pill that will make taking medications easier for HIV positive patients. The incurable infection, HIV (human immunodeficiency virus) leads to AIDS.
The pill, which is an updated version of an older pill named Stribild, contains four HIV drugs, which include elvitegravir, cobicistat, emtricitabine, and tenofovir alafenamide. Unlike the old version, Genvoya was designed to reduce toxic side effects. Stribild, which also contains four drugs, used a different formulation of tenofovir.
"Genvoya contains a new form of tenofovir that has not been previously approved. This new form of tenofovir provides lower levels of drug in the bloodstream, but higher levels within the cells where HIV-1 replicates," the FDA explained in a statement. "Genvoya appears to be associated with less kidney toxicity and decreases in bone density than previously approved tenofovir-containing regimens based on laboratory measures."
