How It Works

Paxlovid is an oral antiviral medication used to treat COVID-19. It is a combination of nirmatrelvir (150mg) and ritonavir (100mg). Nirmatrelvir inhibits the SARS-CoV-2 main protease (Mpro), an enzyme essential for viral replication. By inhibiting this protease, nirmatrelvir prevents the virus from replicating within the body. Ritonavir, on the other hand, is included to boost the levels of nirmatrelvir by inhibiting the enzyme CYP3A4, which breaks down nirmatrelvir in the liver. This combination allows for higher and more sustained levels of nirmatrelvir, enhancing its antiviral efficacy.
