Résumé
Amiodarone increases serum digoxin concentrations, often substantially, and may lead to digoxin toxicity. Additive effects on sinus and AV nodal function raise the risk of bradycardia and heart block. The interaction develops over days to weeks and can persist because of amiodarone's long half-life.
Ce que signifie cette interaction, en termes simples
Amiodarone and Digoxin can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.
Amiodarone belongs to Cardiovascular; Digoxin belongs to Cardiovascular.
Pourquoi elle survient
Amiodarone inhibits P-glycoprotein and reduces renal and non-renal digoxin clearance, with additive pharmacodynamic effects on cardiac conduction.
Conduite à tenir
Reduce the digoxin dose by roughly one-third to one-half when starting amiodarone, or consider stopping digoxin if no longer necessary. Measure serum digoxin levels and review after one to two weeks, and monitor heart rate and ECG.
