Paritaprevir is an antiviral medication, which is derived from chemical synthesis with its action targeting the hepatitis C virus (HCV). It operates primarily as a protease inhibitor, specifically targeting the NS3/4A protease, an essential enzyme for HCV replication. By inhibiting this protease, Paritaprevir effectively disrupts the viral life cycle, preventing the virus from maturing and proliferating within the host cells. Paritaprevir is utilized in the medical field for the treatment of chronic hepatitis C infection, often in combination with other antiviral agents to enhance efficacy and combat different genotypes of the virus. Its application is critical in reducing viral load, improving liver function, and achieving sustained virologic response (SVR) in patients, thereby decreasing the risk of cirrhosis and liver cancer. The strategic inclusion of Paritaprevir in antiviral regimens marks a significant advance in the management of hepatitis C, contributing importantly to public health by decreasing the spread of this infectious disease.

Inhibitor of HCV NS5A

Chemically derived from ritonavir, Lopinavir belongs to the amphetamines. Lopinavir is clinically used in the prevention and treatment of HIV infections as it acts as HIV-1 protease inhibitor. In 2020, lopinavir was tested to treat COVID-19 patients and although it led to a higher rate of gastrointestinal side effects, the Lopinavir-treated group had a lower incidence of severe complications. Overall it was deemed not to work as a treatment. Lopinavir is part of our Bio-X™ Range.
