概要
Amiloride is a potassium-sparing diuretic and captopril reduces aldosterone, so together they can cause significant hyperkalemia, especially in renal impairment or diabetes. The hydrochlorothiazide component partly offsets potassium retention but does not remove the risk. Additive blood pressure lowering may also occur.
この相互作用をわかりやすく説明すると
Amiloride and Captopril-hydrochlorothiazide 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; Captopril-hydrochlorothiazide belongs to Cardiovascular.
なぜ起こるのか
Additive potassium retention from ENaC blockade (amiloride) and reduced aldosterone secretion from ACE inhibition.
対処法
Check serum potassium and creatinine at baseline, within the first week or so, and periodically thereafter. Avoid potassium supplements and salt substitutes, and stop amiloride if hyperkalemia develops.
