Study Design

*This interaction has not been formerly studied, but inferences are drawn from knowledge of the metabolic and transport pathways of each of the drugs.

Study Results

The manufacturer states that coadministration of daclatasvir with inhibitors or inducers of either CYP3A or P-gP may alter daclatasvir concentrations.

Study Conclusions

Inhibitors of P-gP or CYP3A may increase daclatasvir concentrations, while inducers of this enzyme and transport protein may decrease daclatasvir concentrations.
