Impact of Sofosbuvir and Daclatasvir Concentration on HCV RNA

October 19, 2017 updated by: Hospices Civils de Lyon

Sofosbuvir Plus Daclatasvir With or Without Ribavirin for Chronic Hepatitis C Infection: Impact of Drug Concentration on Viral Load Decay

Sofosbuvir plus daclatasvir with or without ribavirin is one of the currently recommended treatment option for chronic hepatitis C. The objectives were to identify factors associated with sofosbuvir/daclatasvir plasma concentrations variations and to evaluate their impact on viral kinetics.
