WHAT ARE HCV NS5A INHIBITORS AND HOW DO THEY WORK?
HCV NS5A inhibitors are a class of drugs used to treat hepatitis C virus (HCV) infections. To know how HCV NS5A inhibitors work, let us first understand the structure of the hepatitis virus. HCV is a small, enveloped RNA virus. The RNA is responsible for viral replication and is surrounded by lipid layers and glycoproteins. It is also responsible for coding several proteins that help the virus to replicate. Some of the proteins associated with viral replication include:
To destroy the HCV virus, it is important to target these proteins to prevent viral replication and thus its progression, which is done by the HCV NS5A inhibitor by inhibiting the action of the NS5A protein. Consequently, viral replication comes to a standstill and ultimately the virus dies.
HOW ARE HCV NS5A INHIBITORS USED?
HCV NS5A inhibitors are mainly administered orally and used to treat:
- Chronic hepatitis C
- HIV infection when used in combination with other drugs
