Lopinavir is an antiretroviral of the protease inhibitor class. It is used against HIV infections as a fixed-dose combination with another protease inhibitor, ritonavir (lopinavir/ritonavir).[1]

It was patented in 1995 and approved for medical use in 2000.[2] Considered now as second-line therapy in the West, it is still prescribed in LMIC, especially among children living with HIV. Lopinavir and ritonavir can be taken as a tablet or an oral solution, a preferred option in children. In the early stages of COVID-19 pandemics, lopinavir was repurposed against the SARS-CoV-2 virus in the hope of disturbing its protease activity.[3]
