Zidovudine (ZDV), also known as azidothymidine (AZT), is an antiretroviral medication used to prevent and treat HIV/AIDS. It is generally recommended for use in combination with other antiretrovirals. It may be used to prevent mother-to-child spread during birth or after a needlestick injury or other potential exposure. It is sold both by itself and together as lamivudine/zidovudine and abacavir/lamivudine/zidovudine. It can be used by mouth or by slow injection into a vein.
The management of HIV/AIDS normally includes the use of multiple antiretroviral drugs as a strategy to control HIV infection. There are several classes of antiretroviral agents that act on different stages of the HIV life-cycle. The use of multiple drugs that act on different viral targets is known as highly active antiretroviral therapy (HAART). HAART decreases the patient's total burden of HIV, maintains function of the immune system, and prevents opportunistic infections that often lead to death. HAART also prevents the transmission of HIV between serodiscordant same-sex and opposite-sex partners so long as the HIV-positive partner maintains an undetectable viral load.
Reverse-transcriptase inhibitors (RTIs) are a class of antiretroviral drugs used to treat HIV infection or AIDS, and in some cases hepatitis B. RTIs inhibit activity of reverse transcriptase, a viral DNA polymerase that is required for replication of HIV and other retroviruses.
Lamivudine, commonly called 3TC, is an antiretroviral medication used to prevent and treat HIV/AIDS. It is also used to treat chronic hepatitis B when other options are not possible. It is effective against both HIV-1 and HIV-2. It is typically used in combination with other antiretrovirals such as zidovudine, dolutegravir, and abacavir. Lamivudine may be included as part of post-exposure prevention in those who have been potentially exposed to HIV. Lamivudine is taken by mouth as a liquid or tablet.
Nevirapine (NVP), sold under the brand name Viramune among others, is a medication used to treat and prevent HIV/AIDS, specifically HIV-1. It is generally recommended for use with other antiretroviral medications. It may be used to prevent mother to child spread during birth but is not recommended following other exposures. It is taken by mouth.
Lamivudine/zidovudine, sold under the brand name Combivir among others, is a fixed-dose combination antiretroviral medication used to treat HIV/AIDS. It contains two antiretroviral medications, lamivudine and zidovudine. It is used together with other antiretrovirals. It is taken by mouth twice a day.
Etravirine is a drug used for the treatment of HIV. Etravirine is a non-nucleoside reverse transcriptase inhibitor (NNRTI). Unlike the currently available agents in the class, resistance to other NNRTIs does not seem to confer resistance to etravirine. Etravirine is marketed by Janssen, a subsidiary of Johnson & Johnson. In January 2008, the Food and Drug Administration approved its use for patients with established resistance to other drugs, making it the 30th anti-HIV drug approved in the United States and the first to be approved in 2008. It was also approved for use in Canada on April 1, 2008.
Telbivudine is an antiviral drug used in the treatment of hepatitis B infection. It is marketed by Swiss pharmaceutical company Novartis under the trade names Sebivo and Tyzeka. Clinical trials have shown it to be significantly more effective than lamivudine or adefovir, and less likely to cause resistance. However, HBV signature resistance mutation M204I or L180M+M204V have been associated with Telbivudine resistance.
Diarylpyrimidines (DAPY) and diaryltriazines (DATA) are two closely related classes of molecules resembling the pyrimidine nucleotides found in DNA. They show great potency in inhibiting the activity of HIV reverse transcriptase. Several compounds in this class are non-nucleoside reverse transcriptase inhibitors used clinically in the treatment of HIV/AIDS, notably etravirine and rilpivirine.
Rilpivirine, sold under the brand names Edurant and Rekambys, is a medication, developed by Tibotec, used for the treatment of HIV/AIDS. It is a second-generation non-nucleoside reverse transcriptase inhibitor (NNRTI) with higher potency, longer half-life and reduced side-effect profile compared with older NNRTIs such as efavirenz.
Apricitabine is an experimental nucleoside reverse transcriptase inhibitor (NRTI) against HIV. It is structurally related to lamivudine and emtricitabine, and, like these, is an analogue of cytidine.
Elvucitabine is an experimental nucleoside reverse transcriptase inhibitor (NRTI), developed by Achillion Pharmaceuticals, Inc. for the treatment of HIV infection.
Dexelvucitabine is a failed experimental agent for the management of human immunodeficiency virus infection. It is a cytidine nucleoside analog and nucleoside reverse transcriptase inhibitor. that inhibits HIV-1 replication in vitro. During phase II clinical trials there was some indication of a decreased mean viral load in patients with infected human immunodeficiency virus.
Non-nucleoside reverse-transcriptase inhibitors (NNRTIs) are antiretroviral drugs used in the treatment of human immunodeficiency virus (HIV). NNRTIs inhibit reverse transcriptase (RT), an enzyme that controls the replication of the genetic material of HIV. RT is one of the most popular targets in the field of antiretroviral drug development.
ViiV Healthcare is a British multinational pharmaceutical company specializing in the research and development of medicines to treat and prevent HIV/AIDS, with global headquarters in London. The company was created as a joint venture by GSK and Pfizer in November 2009, with both companies transferring their HIV assets to the new company. In 2012 Shionogi joined the company. 76.5% of the company is owned by GSK, 13.5% by Pfizer and 10% by Shionogi. This ownership structure may change depending upon the achievement of certain milestones.
Discovery and development of nucleoside and nucleotide reverse-transcriptase inhibitors began in the 1980s when the AIDS epidemic hit Western societies. NRTIs inhibit the reverse transcriptase (RT), an enzyme that controls the replication of the genetic material of the human immunodeficiency virus (HIV). The first NRTI was zidovudine, approved by the U.S. Food and Drug Administration (FDA) in 1987, which was the first step towards treatment of HIV. Six NRTI agents and one NtRTI have followed. The NRTIs and the NtRTI are analogues of endogenous 2´-deoxy-nucleoside and nucleotide. Drug-resistant viruses are an inevitable consequence of prolonged exposure of HIV-1 to anti-HIV drugs.
Abacavir/dolutegravir/lamivudine, sold under the brand name Triumeq among others, is a fixed-dose combination antiretroviral medication for the treatment of HIV/AIDS. It is a combination of three medications with different and complementary mechanisms of action: abacavir, dolutegravir and lamivudine.
Cabotegravir/rilpivirine, sold under the brand name Cabenuva, is a co-packaged antiretroviral medication for the treatment of HIV/AIDS. It contains cabotegravir and rilpivirine in a package with two separate injection vials.
Elsulfavirine is drug used to treat HIV infection. It is a non-nucleoside reverse transcriptase inhibitor (NNRTI). Elsulfavirine is a prodrug which is metabolized to the active antiviral agent deselsulfavirine. It was developed by the Russian company Viriom.
