Darunavir/r

Juan A. Arnaiz · FDA-approved active Small molecule

Darunavir is a protease inhibitor that blocks HIV protease, preventing the cleavage of viral polyproteins and maturation of infectious HIV particles.

Darunavir is a protease inhibitor that blocks HIV protease, preventing the cleavage of viral polyproteins and maturation of infectious HIV particles. Used for HIV-1 infection in treatment-naive patients (in combination with ritonavir and other antiretrovirals), HIV-1 infection in treatment-experienced patients (in combination with ritonavir and other antiretrovirals).

Mechanism of action

Darunavir binds to the active site of HIV protease with high affinity, inhibiting the enzyme's ability to process viral precursor proteins into functional structural and enzymatic proteins. When boosted with ritonavir (a CYP3A4 inhibitor that increases darunavir plasma concentrations), it effectively suppresses viral replication. This combination is used to treat HIV-1 infection in both treatment-naive and treatment-experienced patients.
