Mechanism of Action

OMBITASVIR
Ombitasvir is a direct acting inhibitor of nonstructural protein 5a (ns5a) of hepatitis c virus (hcv). Despite lacking enzymatic activity, ns5a is necessary for viral replication and virion assembly through interaction with other nonstructural proteins
PARITAPREVIR
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
RITONAVIR
Ritonavir inhibits the hiv viral proteinase enzyme which prevents cleavage of the gag-pol polyprotein, resulting in noninfectious, immature viral particles
