Increased plasma conc w/ strong inhibitors of both CYP3A4 & P-gp (eg, ketoconazole, itraconazole, voriconazole & posaconazole) & HIV PIs (eg, ritonavir). Increased plasma conc to a lesser extent w/ active substances which are not considered strong inhibitors of both CYP3A4 & P-gp (eg, amiodarone, clarithromycin, diltiazem, fluconazole, naproxen, quinidine, verapamil). Decreased mean AUC & C
max w/ rifampicin (strong inducer of both CYP3A4 & P-gp). Reduced plasma conc w/ other strong CYP3A4 & P-gp inducers (eg, phenytoin, carbamazepine, phenobarb or St. John's Wort). Increased bleeding risk w/ other anticoagulants, SSRIs/SNRIs, NSAIDs, ASA, P2Y12 inhibitors, other platelet aggregation inhibitors (eg, GPIIb/IIIa receptor antagonists, dipyridamole, dextran or sulfinpyrazone) or thrombolytic agents. Reduced exposure w/ activated charcoal.
