What is Harvoni

Chronic Hepatitis C is a disease of the liver that is caused by the Hepatitis C Virus (HCV). HCV is a very tiny germ that makes copies of itself to survive during the replication process. This single-stranded RNA virus has at least six different strains known as genotypes. Genotype 1 is the most common genotype in the United States that affects 72% of all chronic HCV patients.

Since 2011, with the development of Direct-Acting Antivirals (DAAs) like Ledipasvir, treatment options for chronic Hepatitis C have advanced significantly.

DAAs medications directly interfere with the replication process and block the ability of the hepatitis C virus to make copies of itself. Harvoni is a combination of two DAAs: Sofosbuvir and Ledipasvir. Sofosbuvir is an inhibitor of the HCV NS5B RNA-dependent RNA polymerase and interferes with the reproduction of the virus’s genetic material, stopping the production of new Hep C. Ledipasvir is an NS5A inhibitor and works by interfering with a protein needed to complete the Hep C virus life cycle in the liver cell.
