Lopinavir/ritonavir (Kaletra)
Lopinavir/ritonavir (Kaletra) is a HIV protease inhibitor Small molecule drug developed by Abbott. It is currently FDA-approved for HIV-1 infection in treatment-naïve and treatment-experienced patients, HIV-1 infection in combination antiretroviral therapy. Also known as: lopinavir/ritonavir, Kaletra, Kaletra®, Lopinavir/ritonavir.
Lopinavir and ritonavir are protease inhibitors that block HIV protease, preventing the cleavage of viral polyproteins and stopping HIV replication.
Lopinavir and ritonavir are HIV protease inhibitors that block the viral protease enzyme, preventing the maturation of HIV particles and reducing viral replication. Used for HIV-1 infection in treatment-naïve and treatment-experienced patients, HIV-1 infection in combination antiretroviral therapy.

Mechanism of action
Lopinavir inhibits HIV protease, the enzyme responsible for processing viral proteins necessary for infectious particle formation. Ritonavir is a potent protease inhibitor included as a pharmacokinetic booster that inhibits cytochrome P450 metabolism, dramatically increasing lopinavir plasma concentrations and half-life. Together, they prevent maturation of HIV virions, rendering them non-infectious.
