What it is and how it works
HIV Antiretroviral Therapy Overview refers to a class of medications used to manage human immunodeficiency virus (HIV) infection. These treatments do not cure HIV but aim to control the virus, helping to maintain the immune system and reduce the risk of complications.
Antiretroviral therapy (ART) involves the use of multiple drugs that work together to interrupt the virus’s life cycle. By targeting different stages of viral replication, these medications help to lower the amount of virus in the blood (viral load).
How antiretroviral medications work
- Entry inhibitors: Prevent HIV from entering human immune cells.
- Reverse transcriptase inhibitors: Block the enzyme HIV uses to convert its RNA into DNA, a critical step for viral replication.
- Integrase inhibitors: Stop the viral DNA from integrating into the host cell’s genome.
- Protease inhibitors: Interfere with the production of new viral particles by inhibiting a key enzyme.
The goal of HIV antiretroviral therapy is to reduce viral load to undetectable levels, which helps preserve immune function and lowers the chance of transmission. Healthcare professionals typically tailor treatment plans based on individual patient needs, monitoring response and managing any side effects.
