Antiretroviral therapy (ART) is the use of a combination of antiretroviral drugs to treat HIV infection. It aims to reduce the viral load, improve immune function, and prevent HIV transmission.
congrats on reading the definition of antiretroviral therapy (ART). now let's actually learn it.
ART typically involves a regimen of three or more antiretroviral drugs from at least two different classes.
The goal of ART is to achieve and maintain an undetectable viral load in the patient's blood.
Adherence to ART is crucial for its effectiveness; missing doses can lead to drug resistance.
Common classes of antiretroviral drugs include NRTIs, NNRTIs, PIs, and integrase inhibitors.
Side effects of ART can range from mild (nausea, fatigue) to severe (liver toxicity, metabolic changes).
