What drugs are used in HAART?
Drugs Used in HAART. There are currently five classes of antiretroviral drug, each of which inhibits a specific stage in the HIV life cycle: entry or fusion inhibitors (which include CCR5 receptor antagonists) nucleoside and nucleotide reverse transcriptase inhibitors (NRTI/NtRTI)
Why is it important to monitor HAART regimens?
Monitoring HAART regimens are essential to improve patient outcomes and reduce transmission of HIV, but medication management is a dynamic process that must be monitored by healthcare professionals. Proper utilization and adherence to a HAART regimen are essential to ensure a therapeutic response and prevent viral resistance.
What comprises HAART therapy?
Highly active antiretroviral therapy (HAART) refers to a broad category of treatment regimens usually comprised of three or more antiretroviral drugs that, in previously untreated HIV-1-infected patients, are expected to reduce plasma virus levels below the limits of detection.
When should HAART be started?
Although some HIV-infected pregnant women have conceived on HAART, a significant proportion initiate treatment during pregnancy, primarily to reduce the MTCT risk and the recommendations for when HAART is initiated vary from 10–12 weeks to by 28 weeks gestation.

[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.
When do you start taking highly active antiretroviral therapy?
Currently, the standard of care for a treatment-naïve patient with HIV-1 is a three-drug, highly active antiretroviral therapy (HAART) regimen that is started as soon as possible after a patient tests positive for HIV.

What is a HAART?
Highly active antiretroviral therapy (HAART) is a medication regimen used to manage and treat human immunodeficiency virus type 1 (HIV-1). It is composed of several drugs in the antiretroviral classes of medications. This activity outlines the indications, mechanism of action, and contraindications for various HAART medications in the management ...
What is the goal of HAART?
Reducing the transmission of HIV-1 to others is a primary goal of HAART. With the use of HAART, a reduction of HIV-1 RNA levels has been shown to reduce the risk of sexual transmission to partners to nearly zero in some studies, even among couples that engaged in condomless sexual acts.
What is the standard of care for a patient with HIV-1?
Currently, the standard of care for a treatment-naïve patient with HIV-1 is a three-drug, highly active antiretroviral therapy (HAART) regimen that is started as soon as possible after a patient tests positive for HIV.
What is the cornerstone of HAART?
A fundamental cornerstone of HAART is the co-administration of different drugs that inhibit HIV replication by several mechanisms so that the propagation of a virus with resistance to a single agent is inhibited by the action of the other two agents.
What medications should I avoid with hepatic dysfunction?
Patients with a history of hepatic dysfunction should avoid efavirenz, tenofovir-disoproxil fumarate (TDF), and maraviroc. Patients with a history of renal dysfunction should avoid or adjust dosages of tenofovir, maraviroc, and atazanavir.
Is Integrase inhibitor a good HAART?
Integrase Inhibitors (INSTIs)[39][40][41] INSTIs are generally well-tolerated, and in many cases, they are favorable as the third agent in a HAART regimen due to their neutral effects on cholesterol and triglyceride levels. Some patients may experience dizziness, sleep disturbances, or depression.
Is hepatotoxicity a risk?
There is a risk of hepatotoxicity with allergic features, so patients should be monitored closely for symptoms of allergic reactions or hepatic dysfunction. Drug-drug interactions should be a consideration if patients are taking concurrent CYP3A4 inhibitors or inducers. Contraindications.
What does HAART mean?
Drug Classes. Benefits. HAART is the acronym for "highly active antiretroviral therapy," a term coined in the late 1990s to describe the effectiveness of combination drug therapies used to treat HIV. The term is less commonly used today given that modern antiretrovirals are more than just "highly active" but able to afford people ...
How much is antiretroviral therapy reduced?
Moreover, when antiretroviral therapy is started early, the risk of severe HIV-associated diseases and non-HIV-associated illnesses (like cancers and heart disease) is reduced by as much as 72% , according to research published in the New England Journal of Medicine. 11 .
How many classes of antiretroviral drugs are there?
Today, because of improved pharmacokinetics, some antiretroviral therapies consist of only two drugs. 6. There are currently six classes of antiretroviral drugs able to treat HIV, each of which inhibits a specific stage in the virus's life cycle:
How does treatment as prevention work?
The strategy, known as treatment as prevention, aims to reduce the "community viral load" within a population, making it more difficult to spread infection. 9
What is PREP in HIV?
The strategy, known as pre-exposure prophylaxis (PrEP), is currently recommended for people at high risk of infection, including serodiscordant (mixed-status) couples, injecting drug users, and those who engage in protected anal or vaginal sex. 13 .

What is the difference between HAART and ART?
The main difference between HAART of the late-1990s/early-2000s and ART today is that HIV can truly be considered a chronic, manageable condition. Not only can a 20-year-old diagnosed with HIV today live well into their 70s, but they can do so with drugs that are safer, longer-lasting, and easier to take. 11
What is the treatment for HIV?
ART Today. Antiretroviral therapy is used to treat HIV and is comprised of a combination of drugs that block different stages in the virus' replication cycle. By doing so, the virus can be suppressed to undetectable levels where it can do the body little harm.
What is the name of the drug that combines a newer generation integrase inhibitor with an older
In 2019, the FDA approved the first complete two-drug therapy, known as Dovato, which combines a newer-generation integrase inhibitor called dolutegravir with an older NRTI called lamivudine. The combination has proven to be just as effective as standard triple therapy with fewer side effects. 15.
When was the first protease inhibitor approved?
In 1995, the FDA approved the first protease inhibitor, called Invirase (saquinavir). 1 Unlike other antiretrovirals of the time, which blocked the virus' ability to "hijack" a cell's genetic machinery and turn it into an HIV-producing factory, PIs blocked the virus' ability to assemble new copies of itself from structural proteins.
Is antiretroviral therapy the same as HAART?
Although the goals of antiretroviral therapy remain the same, ART today bears only a glancing resemblance to HAART of the past. Without exception, the benefits of treatment far outweigh any concerns about the drugs or their side effects. Moreover, the benefits extend to those who are not infected.
Is HAART a medical term?
Today, the term HAART is less commonly used and has largely been supplanted in the medical literature by the simplified ART (antiretroviral therapy). The change in terminology is about more than just semantics; it reflects a shift in the goals and benefits of HIV therapy and a step away from what HAART historically implied.
Is HAART a combination therapy?
Redefining Combination Therapy. The term HAART has long been synonymous with triple-drug therapy. And, while it is true that ART typically consists of three or more antiretrovirals, improved pharmacokinetics have now made it possible to treat HIV with only two antiretroviral drugs.
What is a HAART 200 ring?
Dr. Gerdisch: “The HAART 200 and 300 annuloplasty rings provide a reproducible means of creating normal 3-dimensional aortic annulus architecture. The aortic annulus has its own anatomy, with specific 3-dimensional geometry. Using the word “ring” for these devices is a dramatic oversimplification. The HAART rings were developed from scans made of normal humans, translating the consistent geometric pattern into three dimensional rings that are implanted below the aortic valve, dictating the shape of the annulus, and the relationship of the leaflets. The pathologic changes in the annulus configuration are remedied, and the leaflets may then be altered using fine suture to perfect their contour. Rings have been designed for trileaflet (normal) and bicuspid valves.”=
Where are the HAART rings implanted?
The HAART rings were developed from scans made of normal humans, translating the consistent geometric pattern into three dimensional rings that are implanted below the aortic valve, dictating the shape of the annulus, and the relationship of the leaflets.
