Quick Answer: How Do HIV Drugs Work?

How long can you stay undetectable?

A person’s viral load is considered “durably undetectable” when all viral load test results are undetectable for at least six months after their first undetectable test result.

This means that most people will need to be on treatment for 7 to 12 months to have a durably undetectable viral load..

How does HIV medication work?

HIV attacks and destroys the infection-fighting CD4 cells of the immune system. Loss of CD4 cells makes it hard for the body to fight off infections and certain HIV-related cancers. HIV medicines prevent HIV from multiplying (making copies of itself), which reduces the amount of HIV in the body (called the viral load).

What is the best treatment for HIV?

Most people who are getting treated for HIV take 3 or more drugs. This is called combination therapy or “the cocktail.” It also has a longer name: antiretroviral therapy (ART) or highly active antiretroviral therapy (HAART). Combination therapy is the most effective treatment for HIV.

What is the mechanism of action of antiretroviral drugs?

Current ARV mechanisms of action: Block reverse transcriptase to disrupt copying of HIV genetic code (NRTIs; NNRTIs) Block protease enzyme, preventing maturation of new virions (PIs) Prevent fusion of HIV with cell membranes (Fusion inhibitors)

What is the goal of antiretroviral therapy?

The guidelines state that the primary goals of antiretroviral therapy are to maintain maximal suppression of the viral load (i.e., fewer than 50 copies per mL), restore or preserve immunologic function, improve quality of life and reduce HIV-related morbidity and mortality.

What are the classes of antiretroviral drugs?

There are currently 6 major classes of antiretroviral drugs: nucleoside analogue reverse transcriptase inhibitor (NRTI), nonnucleoside reverse transcriptase inhibitor (NNRTI), protease inhibitor (PI), fusion inhibitor, chemokine coreceptor antagonist (consisting of 2 subclasses: CCR5 antagonist and CXCR4 antagonist), …
