	Description	Lopinavir is an antiretroviral protease inhibitor used in combination with other antiretrovirals in the treatment of HIV-1 infection.[L11163] Lopinavir is marketed and administered exclusively in combination with [ritonavir] - this combination, first marketed by Abbott under the brand name Kaletra in 2000, is necessary due to lopinavir's poor oral bioavailability and extensive biotransformation. Ritonavir is a potent inhibitor of the enzymes responsible for lopinavir metabolism, and its co-administration "boosts" lopinavir exposure and improves antiviral activity.[L11163] Like many other protease inhibitors (e.g. [saquinavir], [nelfinavir]), lopinavir is a peptidomimetic molecule - it contains a hydroxyethylene scaffold that mimics the peptide linkage typically targeted by the HIV-1 protease enzyme but which itself cannot be cleaved, thus preventing the activity of the HIV-1 protease.[A191757] Lopinavir was previously under investigation in combination with ritonavir for the treatment of COVID-19 caused by SARS-CoV-2.[L12012]
