What drugs are integrase inhibitors?
The integrase inhibitors currently on the market include:
- raltegravir (Isentress)
- dolutegravir (Tivicay)
- elvitegravir (available in combination with other drugs; no longer available alone)
- bictegravir (available in combination with other drugs; not available alone)
Are integrase inhibitors used for HIV?
Introduction: Integrase inhibitors (INIs) are the latest class of antiretroviral drugs approved for the treatment of HIV infection and are becoming ‘standard’ drugs in the treatment of both naïve as well as heavily pretreated individuals with HIV.
How do integrase strand transfer inhibitors work?
Integrase strand transfer inhibitors (INSTIs) block integrase (an HIV enzyme). HIV uses integrase to insert (integrate) its viral DNA into the DNA of the host CD4 cell. Blocking integrase prevents HIV from replicating.
What does integrase do in HIV?
HIV-1 integrase is a multidomain enzyme which is required for the integration of viral DNA into the host genome. It is one of three enzymes of HIV, the others being the Reverse Transcriptase and the Protease. It is an attractive target for therapeutic drug design.
Which is an integrase inhibitor?
Integrase inhibitors, or INSTIs, are a class of antiretroviral medication that doctors use to treat HIV. Integrase inhibitors block the action of a specific enzyme, HIV integrase, which prevents the virus from multiplying in the blood.
What drug is a non nucleoside reverse transcriptase inhibitor?
2 Non-Nucleoside Reverse Transcriptase Inhibitors. NNRTIs noncompetitively bind to the reverse transcriptase enzyme, altering its conformation to prevent DNA binding [63]. Approved NNRTIs include delavirdine, efavirenz, etravirine, nevirapine, and rilpivirine (Fig. 6.2).
Is Dolutegravir integrase inhibitor?
Dolutegravir, a second-generation integrase inhibitor for the treatment of HIV-1 infection.
What is tenofovir used for?
Tenofovir is used along with other medications to treat human immunodeficiency virus (HIV) infection in adults and children 2 years of age and older. Tenofovir is also used to treat chronic (long term) HBV in adults and children 2 years of age and older weighing 22 pounds (10 kilograms) or more.

Do all viruses have integrase?
This protein, subsequently named integrase (IN), is one of three enzymes encoded in all retroviral genomes [protease (PR), RT, and IN]. All three viral enzymes are contained in virus particles, along with RNA genomes, and are carried into the cell following virus entry.
Do humans have integrase?
Human foamy virus (HFV), an agent harmless to humans, has an integrase similar to HIV IN and is therefore a model of HIV IN function; a 2010 crystal structure of the HFV integrase assembled on viral DNA ends has been determined.
What drug is a non-nucleoside reverse transcriptase inhibitor?
Can you take an integrase inhibitor with HIV?
Pharmacist’s advice. Get their healthcare provider’s approval before taking an integrase inhibitor with any other drug. Other medications may affect how HIV drugs work. These include prescription and over-the-counter drugs, such as calcium, aluminum magnesium antacids, and iron, as well as vitamins and supplements.
When did the FDA approve the use of integrase inhibitors?
The U.S. Food and Drug Administration (FDA) approved the use of integrase inhibitors in 2007. The integrase inhibitors currently on the market include: Dolutegravir and elvitegravir are available in the following combination medications: Integrase inhibitors are often used as the initial medications for treating HIV.
How does the HIV virus control T cells?
HIV does this by making an enzyme called integrase. Integrase allows the DNA of the virus to merge with the DNA of the T cells. Then, the HIV can control what the cells do.
What happens if you stop taking an integrase inhibitor?
If a person taking an integrase inhibitor starts to have uncomfortable side effects, they shouldn’t stop taking the drug without talking to their healthcare provider first. Pausing or changing antiretroviral drugs can do more harm than good. The medications may become less effective, or the virus may become resistant to the drugs altogether.
