Ritonavir (ritonavir) — Uses, Dosage, Side Effects & Safety

Drug class: Antiretroviral, Protease Inhibitor

Overview

Ritonavir is an antiretroviral medication used to treat human immunodeficiency virus (HIV) infection. It is most commonly prescribed in combination with other HIV medicines as part of highly active antiretroviral therapy (HAART). Ritonavir works by inhibiting the protease enzyme, which is essential for the replication of HIV, thereby reducing the amount of virus in the body and helping to maintain immune function. Ritonavir is also widely used as a 'booster' to increase the effectiveness of other protease inhibitors by slowing their breakdown in the body. This allows for lower doses and improved efficacy of these medications. Patients should know that ritonavir does not cure HIV or AIDS, but it helps control the infection and improves quality of life when taken as prescribed.
