Paritaprevir is a direct acting antiviral agent used in combination with other antiviral agents for the treatment of Hepatitis C Virus (HCV) infections.
Paritaprevir is a potent inhibitor of the NS3/4A serine protease of Hepatitis C Virus (HCV) . Following viral replication of HCV genetic material and translation into a single polypeptide, Nonstructural Protein 3 (NS3) and its activating cofactor Nonstructural Protein 4A (NS4A) are responsible for cleaving it into the following structural and nonstructural proteins required for assembly into mature virus: NS3, NS4A, NS4B, NS5A, and NS5B. By inhibiting viral protease NS3/4A, paritaprevir therefore prevents viral replication and function.
When used within the fixed-dose combination product with Ombitasvir, Dasabuvir, and Ritonavir as the FDA-approved product Viekira Pak, paritaprevir is indicated for the treatment of HCV genotype 1b without cirrhosis or with compensated cirrhosis, and when combined with Ribavirin for the treatment of HCV genotype 1a without cirrhosis or with compensated cirrhosis. When used within the fixed-dose combination product with Ombitasvir and Ritonavir as the FDA- and Health Canada-approved product Technivie, paritaprevir is indicated in combination with Ribavirin for the treatment of patients with genotype 4 chronic hepatitis C virus (HCV) infection without cirrhosis or with compensated cirrhosis. When used within the fixed-dose combination product with Ombitasvir, Dasabuvir, and Ritonavir as the Health Canada-approved, commercially available product Holkira Pak, paritaprevir is indicated for the treatment of HCV genotype 1b with or without cirrhosis, and when combined with Ribavirin for the treatment of HCV genotype 1a with or without cirrhosis.
