- Type of Drug: Nucleoside Reverse Transcriptase Inhibitor
Nucleoside reverse transcriptase inhibitors were the first type of drug available to treat HIV. They are also known as NRTIs, nucleoside analogues, or "nukes."
When the HIV virus enters a healthy cell, it attempts to make copies of itself. It does this by using an enzyme called reverse transcriptase. NRTIs block that enzyme, so HIV cannot make new copies of itself.
