►  Drug Interaction : Drug interaction of Tenofovir is with fumanephrotoxic,  NA

  ►    Mechanism of Drug Drug Interaction :  Tenofovir increases the plasma concentrations of didanosine. Once daily triple nucleoside regimens of tenofovir and lamivudine with either abacavir or didanosine are associated with a high level of treatment failure and of emergence of resistance, and should be avoided. Decreased plasma concentrations of atazanavir and increased plasma concentrations of tenofovir occur when tenofovir is given with atazanavir. the effect is significantly reduced when ritonavir is added as a booster. Use of ritonavir-boosted lopinavir with tenofovir modestly increases the plasma concentrations of tenofovir.,
