What is the best medication for HIV patients?
Medications used to treat HIV are called antiretrovirals (also referred to as ART or ARV). Most people with HIV take combination ART every day. ART also reduces the risk of HIV transmission. Approved ARV treatments are grouped into seven drug classes as follows: Integrase strand transfer inhibitors (INSTIs).

Topic Overview. Antiretroviral therapy (ART) is the combination of several antiretroviral medicines used to slow the rate at which HIV makes copies of itself (multiplies) in the body. A combination of three or more antiretroviral medicines is more effective than using just one medicine (monotherapy) to treat HIV.
How do you combine HIV drugs?
Even if a PI can be given as a stand-alone drug, it should always be combined with other HIV medications (antiretrovirals) to create a complete regimen, or antiretroviral therapy. Atazanavir and fosamprenavir are often given together with ritonavir, but in certain situations they don't have to be.

A triple-drug combination of zidovudine, didanosine and nevirapine has been found to outperform combination therapy with two nucleosides as demonstrated by changes in the viral load and the CD4+ count.
Why do we use combination therapy?
Combination therapy has been shown to dramatically reduce the likelihood of drug resistance (many drug-resistant mutations are mutually exclusive) and to suppress viral replication to the point that progression to AIDS is significantly slowed.
Why drug are combined?
The use of drugs in combination can produce a synergistic effect if each of the drugs impinges on a different target or signaling pathway that results in reduction of required drug concentrations for each individual drug. Therefore, use of drug combinations could increase the success rate of drug repurposing screens.
What is recommended that antiretroviral therapy is initiated with a combination of three active antiretrovirals comprised of?
Initial treatment regimens usually include two NRTIs and a third active antiretroviral drug, which may be in the INSTI, NNRTI, or PI class. They may sometimes include a booster, which may be cobicistat (Tybost) or ritonavir (Norvir).

What Is HIV Drug Resistance? Drug resistance can be a cause of treatment failure for people living with HIV. As HIV multiplies in the body, it sometimes mutates (changes form) and produces variations of itself. Variations of HIV that develop while a person is taking ART can lead to drug-resistant strains of HIV.

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.
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.

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.
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 enzymes block HIV?
NRTIs block an enzyme of the human immunodeficiency virus called reverse transcriptase that allows HIV to infect human cells, particularly CD4 cells or lymphocytes. Reverse transcriptase converts HIV genetic material, which is RNA, into human genetic material, which is DNA.
What is the drug that binds to HIV?
A monoclonal antibody called ibalizumab (Trogarzo) binds the CD4 molecule (a receptor for HIV on cells), which prevents viral entry into the cell. Medical professionals administer the drug as an intravenous infusion of 2,000 mg once, then two weeks later at 2,000 mg again, followed by 800 mg every two weeks.
How does HIV get transmitted?
HIV is transmitted through blood and genital secretions; most people get it through sexual contact or sharing needles for illegal IV drug use. HIV can be controlled by a strict drug regimen, but left unchecked, it leads to AIDS. In AIDS, the immune system collapses and the body falls prey to secondary, opportunistic infections and cancers that typically kill the person.
What does less reverse transcriptase mean?
This is an enzyme the virus needs to infect white blood cells. Less reverse transcriptase means fewer newly infected cells. Protease inhibitors, on the other hand, block protease. Protease is crucial for HIV to make copies of itself, so less protease means the virus’ ability to colonize more cells is diminished.

Does TAF affect HIV?
TAF enters the HIV-infected cell much more efficiently than TDF, which results in much lower levels of drug in the blood, but higher levels within the cells where HIV-1 replicates.
