Ritonavir News and Research

RSS

Ritonavir, also known as Norvir, is a type of medicine called a protease inhibitor (PI). PIs act by blocking protease, a protein that HIV needs to make more copies of itself. Ritonavir was approved by the FDA on March 1, 1996, for use with other antiretroviral agents in the treatment of HIV infection in adults and children 2 years of age or older. Ritonavir is now approved with other anti-HIV drugs in the treatment of HIV-1 infection in children in individuals over 1 month in age. Studies have shown that ritonavir works as a booster for some other PIs. Taking ritonavir makes it possible to take a lower dose of the other PIs. This medicine does not cure or prevent HIV infection or AIDS and does not reduce the risk of passing the virus to other people.
