Antiretroviral drugs HIV is treated with antiretroviral medicines, which work by stopping the virus replicating in the body. This allows the immune system to repair itself and prevent further damage. A combination of HIV drugs is used because HIV can quickly adapt and become resistant.
They work by blocking cell receptors, called CCR5 and CXCR4, respectively, and prevent HIV from attaching to the host cell, interrupting the HIV life cycle in its earliest stages. gp120 inhibitors, such as DS003, bind to the gp120 proteins HIV needs to attach to healthy cells.
These drugs are distributed into six distinct classes based on their molecular mechanism and resistance profiles: (1) nucleoside-analog reverse transcriptase inhibitors (NNRTIs), (2) non–nucleoside reverse transcriptase inhibitors (NNRTIs), (3) integrase inhibitors, (4) protease inhibitors (PIs), (5) fusion inhibitors, ...
Classes of antiretroviral agents include the following: Nucleoside or nucleotide reverse transcriptase inhibitors (NRTIs) Protease inhibitors (PIs) Nonnucleoside reverse transcriptase inhibitors (NNRTIs)
Antiretroviral: An agent or process effective against a retrovirus. For example, a drug to treat HIV.Jun 3, 2021
The antiviral drugs target diverse group of viruses such as herpes, hepatitis, and influenza viruses. Whereas antiretroviral are the drugs that are used to fight retrovirus infections which mainly include HIV.
Lipodystrophy, or “lipo” for short, is a collection of body shape changes in people taking antiretroviral medications (ARVs). “Lipo” refers to fat, and “dystrophy” means bad growth. These changes include fat loss, fat deposits, and metabolic changes. Fat loss occurs in the arms, legs, or face (sunken cheeks).
ARVs included green oval tablets (Trizivir), yellow capsules (efavirenz) and round orange-and-white tablets (Lamivir).
Weight gain is a common side effect of antiretroviral therapy (ART). On average, people put on about 4 pounds during the first 2 years of their treatment. Most of that gain happens in the first year.Nov 15, 2021

There are six main types ('classes') of antiretroviral drugs. Each class of drug attacks HIV in a different way. Generally, drugs from two (or sometimes three) classes are combined to ensure a powerful attack on HIV.May 19, 2021
“What people don't know is that ARVs are issued based on an individual assessment done which includes blood tests for liver function, kidney function, haemoglobin level and more. ARVs are prescribed per case so regimens aren't the same.” Nene says people should stop sharing ARVs before things get worse.Aug 15, 2019
