Protease inhibitors (PIs) are medications that act by interfering with enzymes that cleave proteins.
[4] Most ARPIs are peptide-like molecules which resemble the substrate of the viral protease.
The first members of this class, saquinavir, ritonavir, and indinavir, were approved in late 1995–1996.
A drug combination targeting SARS-CoV-2, Paxlovid, was approved in December 2021 to treat COVID-19.
[13] Protease inhibitors can cause a syndrome of lipodystrophy, hyperlipidemia, diabetes mellitus type 2, and kidney stones.
