Mechanism of action

Nelfinavir binds to the active site of HIV protease, a viral enzyme essential for processing precursor proteins into functional structural and enzymatic proteins. By inhibiting this protease, the drug prevents the formation of mature, infectious viral particles, thereby reducing viral replication and slowing disease progression. It is typically used as part of combination antiretroviral therapy (cART) in HIV-infected patients.
