New treatments being offered for HIV include nucleotide reverse transcriptase inhibitors, protease inhibitors, non-nucleotide reverse transcriptase inhibitors and entry/fusion inhibitors. These drugs are known as antiretrovirals or highly active antiretroviral therapy, notes AIDS.gov.
These treatments work differently to prevent HIV from replicating in the body of a patient. NRTIs prevent HIV from reproducing, while NNRTIs prevent HIV from making copies of its own DNA. Protease inhibitors block the enzyme that breaks down HIV genetic material into functional pieces by stopping it from replicating. Entry/fusion inhibitors prevent the HIV virus from entering the body cells by blocking the receptor sites, explains AIDS.gov.
