Antiretroviral Therapy : A Complete Guide to HIV Treatment
Antiretroviral Therapy (ART) is the standard treatment for people living with Human Immunodeficiency Virus (HIV). It involves taking a combination of antiretroviral medicines every day to suppress the virus, protect the immune system, and prevent the progression of HIV to AIDS. While ART does not cure HIV, it enables individuals to live long, healthy, and productive lives.
How Does Antiretroviral Therapy Work?
ART works by targeting different stages of the HIV life cycle, preventing the virus from multiplying. As the viral load decreases, the immune system recovers and becomes more effective at fighting infections. Consistent treatment can reduce HIV to undetectable levels, meaning the virus cannot be sexually transmitted—a concept known as Undetectable = Untransmittable (U=U).
Key Benefits of ART
Suppresses HIV replication and lowers viral load.
Strengthens the immune system by preserving CD4 cells.
Reduces the risk of opportunistic infections.
Prevents the transmission of HIV to sexual partners and from mother to child during pregnancy.
Improves life expectancy and overall quality of life.
Types of Antiretroviral Drugs
ART typically combines medicines from different drug classes, including:
Nucleoside Reverse Transcriptase Inhibitors (NRTIs)
Non-Nucleoside Reverse Transcriptase Inhibitors (NNRTIs)
Protease Inhibitors (PIs)
Integrase Strand Transfer Inhibitors (INSTIs)
Entry and Fusion Inhibitors
