摘要
Losartan and amiloride both raise serum potassium, and the potassium-lowering effect of hydrochlorothiazide only partly offsets this. Hyperkalemia can occur, especially in patients with renal impairment, diabetes or older age.
用白話說明這項交互作用的意義
Amiloride and Hydrochlorothiazide-losartan 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.
Amiloride belongs to Cardiovascular; Hydrochlorothiazide-losartan belongs to Cardiovascular.
為什麼會發生
Angiotensin receptor blockade reduces aldosterone-mediated potassium excretion while amiloride blocks the epithelial sodium channel, additively causing potassium retention.
處置方式
Check serum potassium and creatinine within the first week or so and periodically thereafter. Avoid potassium supplements and salt substitutes, and stop amiloride if potassium becomes elevated.
