Sofosbuvir

Indication:

It is used for the treatment of hepatitis Cvirus (HCV) infection. Compared to previous treatments, sofosbuvir-based regimens provide a higher cure rate, fewer side effects, and a two- to four-fold reduced duration of therapy.  Sofosbuvir allows most patients to be treated successfully without the use of peginterferon, an injectable drug with severe side effects^.  that is a key component of older drug combinations for the treatment of HCV.

Mechanism of action:

Sofosbuvir contains oral nucleotide analog inhibitor of the hepatitis C virus (HCV) polymerase. The drug is a direct-acting antiviral agent and interferes straight with the HCV lifecycle, restraining the viral replication. It can be incorporated into HCV RNA by the NS5B polymerase and acts as a chain terminator. The drug is available for oral use in the form of 400mg tablets.

The recommended daily dose of Sofosbuvir is 400mg tablet to be taken once daily with or without food. Sofosbuvir should be used in combination with Ribavirin or in combination with Pegylated Interferon and Ribavirin for the treatment of CHC (Chronic Hepatitis C) in adults. It is highly advisable to administer the drug under strict medical supervision and advice.
