Differential changes in lymphocyte beta 2-adrenoceptor density by beta-blocker administration: role of intrinsic sympathomimetic activity.

abstract：:The oral anticoagulant edoxaban, a factor Xa inhibitor, will likely be coadministered with digoxin in some patients with atrial fibrillation. Both drugs are substrates for P-glycoprotein. The objective of this phase 1, parallel study was to assess the effects of coadministration of both drugs on their respective pharm...
