Sofosbuvir

We are highly reputed manufacturer, supplier and exporter of Sofosbuvir in Surat, Gujarat, India. Sofosbuvir is a prodrug nucleotide analog used as part of combination therapy to treat hepatitis C virus (HCV) infection or to treat co-infection of HIV and HCV. After metabolism to the active antiviral agent 2'-deoxy-2'-I -fluoro-I -C-methyluridine-5'-triphosphate (also known as GS-461203), the triphosphate serves as a defective substrate for the NS5B protein, an RNA-dependent RNA polymerase required for replication of viral RNA. Sofosbuvir and other nucleotide inhibitors of the HCV RNA polymerase exhibit a very high barrier to resistance development. This is an important advantage relative to HCV drugs that target other viral enzymes such as the protease, for which rapid resistance development has proved to be an important cause of therapeutic failure. More recently, sofosbuvir has become available as a fixed dose drug combination product with levipasvir used for the treatment of chronic Hepatitis C, an infectious liver disease caused by infection with Hepatitis C Virus (HCV). Approved in October 2014 by the FDA, ledipasvir and sofosbuvir are direct-acting antiviral agents indicated for the treatment of HCV genotype 1 with or without cirrhosis.
