The active ingredient present in Generic Harvoni is a two drug combination for the treatment of hepatitis C. It is administered as a single daily pill containing 90 mg of the viral NS5A inhibitor ledipasvir and 400 mg of sofosbuvir, a nucleotide inhibitor of the viral RNA polymerase.
Sofosbuvir is a nucleotide analog used in combination with other drugs for the treatment of hepatitis C virus (HCV) infection. Sofosbuvir inhibits the RNA polymerase that the hepatitis C virus uses to replicate its RNA.
Ledipasvir (formerly GS-5885) is a drug for the treatment of hepatitis C. Ledipasvir is an inhibitor of the hepatitis C virus NS5A protein.
The ledipasvir/sofosbuvir combination is a direct-acting antiviral agent that interferes with HCV replication and can be used to treat patients with genotypes 1a or 1b without PEG-interferon or ribavirin.
