How Does It Work?

Etravirine belongs to a group of HIV medications known as non-nucleoside reverse transcriptase inhibitors (NNRTIs). These medicines work by blocking a process that the HIV virus needs in order to multiply.
 
HIV (human immunodeficiency virus) is the virus that causes AIDS. Like other viruses, HIV must use a person's own cells to reproduce. However, HIV is a little different from other viruses because it must first convert its genetic material from RNA to DNA. It is the DNA genes that allow HIV to multiply.
 
HIV converts its genetic material by using a special protein called the reverse transcriptase enzyme. To create DNA, this enzyme uses several different molecular building blocks. Etravirine works by attaching to the reverse transcriptase enzyme, stopping it from making DNA. Without DNA, HIV cannot multiply. As a result, the "viral load" (the amount of HIV in the blood) may decrease, which can decrease the risk of progression to AIDS and death.
