25 antiretroviral drugs were available in 2009 for the treatment of HIV infection. The drugs belong to six different classes that act at different targets. The most popular target in the field of antiretroviral drug development is the HIV-1 reverse transcriptase (RT) enzyme. [ 1 ]
The Stanford HIV RT and Protease Sequence Database (also called the “HIV Drug Resistance Database”) was formed in 1998 with HIV reverse transcriptase and protease sequences from persons with well-characterized antiretroviral treatment histories, and is publicly available to query resistance mutations and genotype-treatment, genotype ...
The first-line treatment is generally given to patients as an initial antiretroviral therapy and is the cheapest of the stages of treatments. [1] The first-line antiretroviral drug treatment as recommended by the World Health Organization (WHO) involves TDF (tenofovir), 3TC (lamivudine) or FTC (emtricitabine), and EFV (efavirenz) or dolutegravir (DTG).
The sailor had first presented symptoms in 1969, eight years after he first spent time in ports along the West African coastline. A gonorrhea infection during his first African voyage shows he was sexually active at this time. Tissue samples from the sailor and his wife were tested in 1988 and found to contain HIV-1 (Group O).

Antiretroviral drugs are used to manage HIV/AIDS. Multiple antiretroviral drugs are often combined into a single pill in order to reduce pill burden . Some of these combinations are complete single-tablet regimens; the others must be combined with additional pills to make a treatment regimen.
In 2021, Viatris was ranked 5th by Fortune on its annual "Change the World" list for having "transformed the treatment of HIV around the world in the [previous] five years through the first low-cost antiretroviral drug for first-line treatment of HIV and a children's version in the form of fruit-flavored tablets that dissolve in liquid.

Resistance ranged from 3.9% to 8.6% and reached 19.6% among people who have received and transitioned to a dolutegravir-containing antiretroviral therapy (ART) regimen to combat high HIV viral loads.
Currently, appearance of drug resistant viruses is an inevitable consequence of prolonged exposure of HIV-1 to antiretroviral therapy. Drug resistance is a serious clinical concern in treatment of viral infection, and it is a particularly difficult problem in treatment of HIV. [25] Resistance mutations are known for all approved NRTIs. [26]
