Mechanisms of Action

These newer hepatitis c drugs work through inhibition of HCV NS3/4A protease or HCV NS5A/NS5B enzymes and some may be combined with a CYP3A4 inhibitor. HCV NS3/4A protease is an enzyme important for HCV replication and reproduction.

HCV NS5A and NS5B enzymes play a key role in HCV RNA replication and viral assembly. Replication is the process in which the virus uses the host’s cells mechanism to create more virus RNA. Viral assembly is putting that RNA into an actual virus structure which allows HCV to spread.

Some of these drugs may be combined with a CYP3A4 inhibitor, an enzyme involved in the metabolism of potentially toxic compounds, including drugs. Medications that inhibit CYP3A4 can increase the effects of medications that are broken down by these enzymes.
