How It Works
glecaprevir/pibrentasvir

Mavyret contains glecaprevir and pibrentasvir. Glecaprevir blocks a protein called NS3/4A protease that the virus needs to multiply. Pibrentasvir blocks a protein called NS5A, also needed for the virus to multiply. By blocking these proteins, Mavyret stops the hepatitis C virus from spreading in your body.

itraconazole

Itraconazole stops fungi from growing. It does this by interfering with the production of a substance fungi need to build their cell membranes. This eventually kills the fungus and clears the infection.
