Summary

Lamivudine vs Daclatasvir ^

Study Design

This combination has not been studied, but given what is known about the metabolic and transport pathways of both of these agents, an interaction is not expected.

Study Results

When used as part of an antiretroviral regimen, in patients who are coinfected with HCV and HIV, zidovudine exposures are not expected to change in the presence of daclatasvir. Similarly, daclatasvir concentration is not expected to be altered due to zidovudine.

Study Conclusions

Manufacturer states that an interaction with NRTIs or Entry Inhibitors is not expected and a dose adjustment is not required for either agent. Given the role of other agents in the antiretroviral regimen, daclatasvir concentrations may be altered. Please see other drugs for individual interaction potential.
