Quick Summary

Ritonavir is an antiviral drug that functions as a protease inhibitor. It is administered orally, often in combination with other medications, to treat viral infections such as HIV infection and hepatitis C. As a protease inhibitor, ritonavir works by blocking the action of viral enzymes essential for the synthesis of new viral particles, thereby hindering the spread of the virus to uninfected cells. This mechanism helps to suppress viral replication more effectively when used with other antiviral agents.12
