What is Olysio
Olysio is a protease inhibitor used for treating chronic hepatitis C virus (HCV) infections. It is a direct acting antiviral agent. Olysio reduces the activity of hepatitis C virus protease enzymes which leads to the formation of defective viruses that are unable to multiply in the liver. As a result the hepatitis C viral load decreases.
What is Olysio used for
Olysio is used for treatment of chronic hepatitis C infection in adults. It must be used in combination with peginterferon alfa and ribavirin therapy. It is effective for HCV genotype 1 infection with compensated liver disease, including cirrhosis. An alternative therapy should be considered in patients with HCV genotype 1a containing the Q80K polymorphism. HCV has more than six different genotypes. Genotype means the genetic makeup of living things. Genotyping is used to identify the different types of HCV.
How well does Olysio work
The efficacy of Olysio was evaluated in 4 clinical studies. All subjects received 12 weeks of once daily treatment with 150 mg Olysio or placebo plus pegylated interferon alpha and ribavirin, followed by 12 or 36 weeks of therapy with peginterferon alpha and ribavirin.
