Antiretroviral Drugs 

Antiretroviral drugs (ARVs) are medications used to treat and manage human immunodeficiency virus (HIV) infection. They work by inhibiting the replication of HIV, preventing it from multiplying in the body and slowing down the progression of the disease. 

Types of ARVs 

There are several classes of ARVs, each targeting different stages of the HIV replication cycle. Some common classes include: Nucleoside reverse transcriptase inhibitors (NRTIs), Non-nucleoside reverse transcriptase inhibitors (NNRTIs), Protease inhibitors (PIs), Integrase inhibitors (INSTIs), and Entry inhibitors. 

Combination Therapy 

ARVs are typically used in combination (antiretroviral therapy or ART) to achieve better results. This combination therapy helps to target HIV at multiple points in its replication cycle and reduce the risk of resistance. 

Benefits of ARVs Suppress HIV replication, Reduce viral load in the blood, Improve immune function, Delay the progression of AIDS, and Extend life expectancy.
