Why is this medication prescribed?

Viekira Pak is prescribed for the treatment of chronic hepatitis C, a viral infection that affects the liver. Specifically, it is indicated for adults with genotype 1 chronic hepatitis C virus (HCV) infection, including those with compensated cirrhosis (scarring of the liver). The medication is a combination of several drugs designed to inhibit the replication of the hepatitis C virus.

The key components of Viekira Pak include:

• Ombitasvir: An NS5A inhibitor that targets a protein necessary for the replication of the hepatitis C virus.
• Paritaprevir: A protease inhibitor that also works to prevent the replication of the virus.
• Ritonavir: Included to boost the levels of paritaprevir in the blood, enhancing its effectiveness in suppressing the virus.
• Dasabuvir: A non-nucleoside NS5B polymerase inhibitor, targeting another aspect of the virus’s replication process.

The goal of treatment with Viekira Pak is to achieve sustained virologic response (SVR), which means that the virus is no longer detectable in the blood six months after completing the course of treatment. Successful treatment can lead to a cure for hepatitis C, preventing further liver damage and reducing the risk of complications such as cirrhosis and liver cancer.
