摘要
Hypokalemia and hypomagnesemia induced by chlorthalidone sensitize the myocardium to digoxin and increase the risk of digoxin toxicity and arrhythmias. The risk is greater in elderly patients and those with renal impairment.
用白話說明這項交互作用的意義
Chlorthalidone 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.
Chlorthalidone belongs to Cardiovascular; Digoxin belongs to Cardiovascular.
為什麼會發生
Diuretic-induced potassium and magnesium depletion increases digoxin binding to Na+/K+-ATPase and enhances its proarrhythmic effects.
處置方式
Monitor serum potassium and magnesium regularly and keep potassium in the normal range. Check digoxin level and ECG if symptoms of toxicity occur.

How serious is the interaction between Chlorthalidone and Digoxin?
MediHelp rates it major, on a four-level scale (minor, moderate, major, contraindicated) based on published labels and references. What to do, in brief: Monitor serum potassium and magnesium regularly and keep potassium in the normal range. Check digoxin level and ECG if symptoms of toxicity occur.
What other medicines interact with Chlorthalidone?
MediHelp also lists interactions of Chlorthalidone with, for example, Amifostine, Atenolol-chlorthalidone, Candesartan-hydrochlorothiazide. The full list is on the Chlorthalidone page.
