P-gp Inhibitors Treatment of NVAF Based on clinical experience from the ENGAGE AF-TIMI 48 study, dose reduction in patients concomitantly receiving P-gp inhibitors resulted in edoxaban blood levels that were lower than in patients who were given the full dose.
Consequently, no dose reduction is recommended for concomitant P-gp inhibitor use [see Dosage and Administration (2.1) , Clinical Pharmacology (12.3) , and Clinical Studies (14.1) ] .
From the Ketoconazole label · effective 2026-07-07
Anticoagulants and Antiplatelet Drugs rivaroxaban cilostazol, coumarins, dabigatran Cilostazol: Concomitant administration of single doses of cilostazol 100 mg and ketoconazole 400 mg approximately doubled cilostazol concentrations and altered (increase/decrease) the concentrations of the active metabolites of cilostazol.
Coumarins: Ketoconazole may enhance the anticoagulant effect of coumarin-like drugs, thus the anticoagulant effect should be carefully titrated and monitored.
