摘要
Amphotericin B often causes hypokalemia and hypomagnesemia, which sensitise the myocardium to digoxin. This can precipitate digoxin toxicity with arrhythmias even at normal serum digoxin levels.
用白話說明這項交互作用的意義
Amphotericin b 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.
Amphotericin b belongs to Anti Fungals; Digoxin belongs to Cardiovascular.
為什麼會發生
Electrolyte depletion (potassium, magnesium) from amphotericin B increases digoxin cardiac sensitivity.
處置方式
Monitor potassium and magnesium frequently and keep them in the normal range with supplements. Check digoxin levels and ECG, and watch for signs of toxicity.
