What is antiretroviral therapy?

What's the meaning of antiretroviral?
Listen to pronunciation. (AN-tee-REH-troh-VY-rul THAYR-uh-pee) Treatment with drugs that inhibit the ability of the human immunodeficiency virus (HIV) or other types of retroviruses to multiply in the body.
What Is Antiretroviral Therapy?
Antiretroviral therapy (ART) involves using two or more antiretroviral drugs to suppress the virus to undetectable levels in the blood. This treatment can slow the progression of the disease to a point at which you can live a long, healthy life. 4
How It Works
Antiretroviral drugs do not kill HIV. Rather, they prevent the virus from making copies of itself by blocking stages in the virus's life cycle (also known as the replication cycle ). Antiretrovirals are so named because HIV is a type of virus known as a retrovirus. 4
Side Effects
While all drugs can cause side effects, current antiretrovirals tend to cause far fewer side effects than drugs of the past. Even so, side effects can occur and, in rare cases, be severe.
Tests
Once you have been diagnosed with HIV, your doctor will advise to you start treatment immediately to bring the virus under control. You will not only be counseled on how to take your drugs correctly (including dietary restrictions) but also advised on ways to maintain optimal adherence .
Other Treatments
There are no other medications other than antiretrovirals that can control HIV.
Talk to Your Doctor
The choice of ART relies heavily on the results of a genetic resistance test that helps determine which antiretrovirals work best based on your virus's genetic profile. But it is not the sole factor involved in the selection of ART. 17
Summary
Antiretroviral therapy is used to control HIV. It relies on drugs that inhibit points of the viral replication cycle so the virus cannot make copies of itself and infect immune system cells. Antiretroviral drugs are usually given daily in the form of a pill, which may contain a combination of drugs. These medications may have side effects.
What is the purpose of antiretroviral drugs?
Latesha Elopre, MD, MSPH. on May 20, 2021. Ridofranz / Getty Images. Antiretroviral drugs are used to treat HIV infection. They work by blocking a stage of the virus's life cycle and, by doing so, prevent the virus from replicating.
What is the drug class for HIV?
By doing so, HIV can begin to churn out multiple copies of itself. Nucleoside reverse transcriptase inhibitors (NRTIs) block the action of reverse transcriptase and so prevent the replication of the virus. DRUG CLASS: Nucleoside Reverse Transcriptase Inhibitors (NRTIs) Brand Name. Generic Name.

An Overview of HIV Treatment.
What is the name of the drug that blocks reverse transcriptase?
Non-nucleoside reverse transcriptase inhibitors (NNRTIs) also block reverse transcriptase but in a different way. Rather than attaching to viral DNA like NRTIs do, NNRTIs bind directly to the enzyme, blocking its action.
What enzyme is used to replicate HIV?
Nucleoside Reverse Transcriptase Inhibitors. In order for HIV to replicate, it uses an enzyme called reverse transcriptase to translate its viral RNA into double-stranded DNA, which is then integrated into the nucleus of the host cell to "hijack" its genetic machinery.
How does HIV produce long chain proteins?
Once HIV takes over the genetic machinery of the host cell, it produces long-chain proteins that must be cut into smaller pieces (by protease) in order to be assembled into a new viral particle. By binding to protease, the long-chain proteins cannot be cut and new viral particles cannot be produced.
How do entry/attachment inhibitors work?
Entry/Attachment Inhibitors. As per their name, entry/attachment inhibitors work by blocking the virus's ability to attach to or enter healthy host cells. They do so by binding to different receptors on the surface of the host cell that HIV uses to lock onto and/or enter the cell.

What is the entry inhibitor for HIV?
Entry Inhibitors#N#Entry inhibitors block HIV entry into CD4+ cells.#N#Fusion inhibitors#N#The only drug in this class is T-20, which is administered as a twice daily subcutaneous injection. The most common side effect is redness and pain at the site of injection. Rarely, infection can occur at the injection site. There also are reports of generalized allergic reactions.#N#CCR5 antagonist#N#Although there were some early concerns of liver inflammation for drugs in this class, MVC appeared to be well tolerated in clinical trials without any specific toxicities attributable to the drug. However, it is a new drug in a new class and the first to actually target the cell. For these reasons, longer follow-up from clinical trials and those followed in the clinic will be very important for assessing the overall safety of the drug.
What is the function of NRTIs?
NRTIs block an enzyme of the HIV called reverse transcriptase that allows HIV to infect human cells, particularly CD4 T cells or lymphocytes . Reverse transcriptase converts HIV genetic material, which is RNA, into human genetic material, which is DNA. The human-like DNA of HIV then becomes part of the infected person's own cells, allowing the cell to produce RNA copies of the HIV that can then go on to attack other not yet infected cells. Thus, blocking reverse transcriptase prevents HIV from taking over (infecting) human cells.
What is the first drug to be approved for treatment?
