Antiretroviral therapy works by preventing viral replication in the body. This allows the body’s immune system to recover. ART is a combination of drugs that act on the virus in different ways at different stages in its life cycle. Unlike bacteria, viruses cannot multiply on their own.
What does ART or antiretroviral therapy do?
Antiretroviral treatment (also known as antiretroviral therapy or ART) are the drugs that treat HIV. Taking ART means that people living with HIV can live long and healthy lives. ART is not a cure for HIV, but it keeps HIV under control, so it doesn’t affect your health and you can carry on with life as usual.
How does combination antiretroviral therapy work?
Treatment that uses a combination of three or more drugs to treat HIV infection. Combination antiretroviral therapy stops the virus from making copies of itself in the body. This may lessen the damage to the immune system caused by HIV and may slow down the development of AIDS.
How do antiretroviral drugs work answers?

What does ART medication do?
ART are medications that treat HIV. The drugs do not kill or cure the virus. However, when taken in combination they can prevent the growth of the virus. When the virus is slowed down, so is HIV disease.
How long does it take for antiretrovirals to work?
Most people living with HIV who start taking antiretroviral therapy daily as prescribed achieve an undetectable viral load within one to six months after beginning treatment.
What are the five goals of antiretroviral therapy?
Thus, once initiated, ART should be continued, with the following key treatment goals: Maximally and durably suppress plasma HIV RNA; Restore and preserve immunologic function; Reduce HIV-associated morbidity and prolong the duration and quality of survival; and. Prevent HIV transmission.
What are the three active antiretrovirals?
Most HAART regimens include drugs from at least two of the three classes of antiretroviral therapy (nucleoside analog reverse transcriptase (RT) inhibitors, non-nucleoside analog RT inhibitors, and protease inhibitors).
What is the difference between Haart and ART?
HARRT is what people used to called HIV medication. This being highly active antiretroviral therapy. ART is just another way to say HIV medication. ART that is prescribed in Nepal is just as effective as ART that is prescribed in the UK.
What is the difference between antiviral and antiretroviral?
The antiviral drugs target diverse group of viruses such as herpes, hepatitis, and influenza viruses. Whereas antiretroviral are the drugs that are used to fight retrovirus infections which mainly include HIV. Different classes of antiretroviral drugs act on different stages of the HIV life cycle..
When taking antiretroviral therapy ART what adherence are patients asked to achieve?
Even though access to ART is vital; ensuring the patients’ adherence to the prescribed regimen is equally important. In order to attain a successful treatment outcome, the current treatment for HIV/AIDS regimen requires adherence level of greater than 95 % [1–5].
Why are antiretroviral drugs given in combination?
Antiretroviral drugs HIV is treated with antiretroviral medicines, which work by stopping the virus replicating in the body. This allows the immune system to repair itself and prevent further damage. A combination of HIV drugs is used because HIV can quickly adapt and become resistant.
What is the difference between hiv1 and hiv2?
HIV-1 is the most common type of HIV and accounts for 95% of all infections, whereas HIV-2 is relatively uncommon and less infectious. HIV-2 is mainly concentrated in West Africa and the surrounding countries. HIV-2 is less fatal and progresses more slowly than HIV-1.
How long does it take to gain weight after starting ARVs?
Investigational ARVs were consistently associated with more weight gain than the approved drugs to which they were being compared. Across all the studies, participants gained a median of 4.4 pounds after 96 weeks of treatment, with the greatest proportion of that weight gain occurring during the first 48 weeks.
Do you have to tell someone you are undetectable?
Having an undetectable viral load and continuing to stay on medication means you are not putting your partner(s) at risk. There is no moral imperative to disclose when you are not putting your partner at risk.
What are the Art goals?
ART can reduce perinatal transmission by several mechanisms, including lowering maternal antepartum viral load and preexposure and postexposure prophylaxis of the infant. Therefore, for prevention of perinatal transmission of HIV, combined antepartum, intrapartum, and infant antiretroviral prophylaxis is recommended.
Why is nevirapine not used in PEP?
In 2001, the US Food and Drug Administration (FDA) recommended avoiding the use of nevirapine for post-exposure prophylaxis (PEP) after several high profile life-threatening side-effects of nevirapine – including liver failure and severe skin reactions – were reported amongst people taking nevirapine as PEP.
What are antiretroviral regimens?
The use of HIV medicines to treat HIV infection is called antiretroviral therapy (ART). People on ART take a combination of HIV medicines (called an HIV treatment regimen) every day. The U.S. Food and Drug Administration (FDA) has approved more than 30 HIV medicines to treat HIV infection.

Which is usually the most important consideration in the decision to initiate antiretroviral therapy?
[17,18] Regardless of CD4 cell count, the decision to initiate ART should always include consideration of any co-morbid conditions, the willingness and readiness of the patient to initiate therapy, and the availability of resources.
