- Epclusa contains two antiviral ingredients, sofosbuvir and velpatasvir, and may be used to treat hepatitis C.
- Sofosbuvir interferes with the reproduction of genetic material of the hepatitis C virus, by inhibiting an RNA-dependent polymerase called HCV NS5B, which is also needed by the virus to replicate itself.
- Velpatasvir works by interfering with a protein, called HCV NS5A that is needed by the virus to replicate itself.
Epclusa contains two antiviral ingredients, sofosbuvir and velpatasvir, and may be used to treat chronic hepatitis C in adults and children over the age of six.
Sofosbuvir interferes with the reproduction of genetic material of the hepatitis C virus, by inhibiting an RNA-dependent polymerase called HCV NS5B, which is also needed by the virus to replicate itself. Sofosbuvir is a prodrug, which means it is metabolized in the body to its active component and incorporated into the DNA of the HCV virus. Sofosbuvir also works directly on viral RNA and does not inhibit human DNA or RNA.
Velpatasvir is an NS5A (hepatitis C virus nonstructural protein 5A) inhibitor. Velpatasvir works by interfering with a protein, called HCV NS5A that is needed by the virus to replicate itself. This protein is the main target for velpatasvir, meaning velpatasvir works directly on the virus, not on human cells.
