설명
Valsartan may slightly increase digoxin plasma levels by reducing its renal clearance; the interaction is generally modest.
기전
Angiotensin II promotes renal tubular secretion of digoxin; ARB-mediated angiotensin II blockade may reduce this secretion, marginally raising digoxin levels.
임상적 중요성
Small increase in digoxin exposure; rarely clinically significant unless patient is already at the upper end of the therapeutic range.
관리 방법
Monitor digoxin levels when initiating valsartan in digitalized patients; adjust dose if levels exceed 1.2 ng/mL.
