Glecaprevir and Pibrentasvir: A Breakthrough Treatment for Hepatitis C
Glecaprevir and Pibrentasvir are a powerful combination of antiviral medications used to treat chronic hepatitis C virus (HCV) infection in adults and children aged 3 years and older. Marketed under the brand name Mavyret, this fixed-dose combination therapy offers a highly effective, pangenotypic solution for most HCV genotypes (1 through 6).
What Are Glecaprevir and Pibrentasvir?
-
Glecaprevir is an HCV NS3/4A protease inhibitor.

Pibrentasvir is an HCV NS5A inhibitor.
Together, these direct-acting antivirals (DAAs) work by blocking the proteins essential for the replication of the hepatitis C virus, leading to viral clearance.

Short Treatment Duration: In many cases, just 8 weeks of therapy is sufficient.
-
Pangenotypic Coverage: Effective against all major HCV genotypes.
-
No Need for Ribavirin: Most patients do not require ribavirin or interferon.
