Molnupiravir is an antiviral medication developed to treat mild to moderate COVID-19 infection in adults who are at high risk of developing severe illness. This oral medication targets the SARS-CoV-2 virus, reducing the viral load in the body and helping prevent the progression of COVID-19. Molnupiravir is often prescribed when patients cannot access other COVID-19 treatments or need additional options for managing the virus at its early stages.

Mode of Action:

Molnupiravir works by targeting and disrupting the RNA replication process of SARS-CoV-2, the virus responsible for COVID-19. The active form of Molnupiravir incorporates itself into the viral RNA, causing mutations in the virus's genetic code. These mutations hinder the virus's ability to replicate effectively, thereby lowering viral load and reducing the severity and duration of the infection.
