Darunavir

**Semantic type:** Pharmacologic Substance

**Definition:** A human immunodeficiency virus type 1 (HIV-1) protease nonpeptidic inhibitor, with activity against HIV. Upon oral administration, darunavir selectively targets and binds to the active site of HIV-1 protease, and inhibits the dimerization and catalytic activity of HIV-1 protease. This inhibits the proteolytic cleavage of viral Gag and Gag-Pol polyproteins in HIV-infected cells. This inhibition leads to the production of immature, non-infectious viral proteins that are unable to form mature virions, and prevents HIV replication.
