Wechselwirkung zwischen Eplerenon und Quinapril

…sometimes associated with oliguria and/or progressive azotemia, and rarely with acute renal failure and/or death, include patients with the following conditions or characteristics: heart failure, hyponatremia, high dose diuretic therapy, recent intensive diuresis or increase in diuretic dose, renal dialysis, or severe volume and/or salt depletion of any etiology.

It may be advisable to eliminate the diuretic (except in patients with heart failure), reduce the diuretic dose or cautiously increase salt intake (except in patients with heart failure) before initiating therapy with quinapril hydrochloride in patients at risk for excessive hypotension who are able to tolerate such adjustments.

Such patients should be followed closely for the first two weeks of treatment and whenever the dose of quinapril hydrochloride and/or diuretic is increased.

If symptomatic hypotension develops, a dose reduction or discontinuation of quinapril hydrochloride or concomitant diuretic may be necessary.

Drug Interactions Concomitant diuretic therapy As with other ACE inhibitors, patients on diuretics, especially those on recently instituted diuretic therapy, may occasionally experience an excessive reduction of blood pressure after initiation of therapy with quinapril hydrochloride.

ACE Inhibitors and Angiotensin II Receptor Antagonists The risk of hyperkalemia increases when eplerenone is used in combination with an ACE inhibitor and/or an ARB.

Lithium toxicity has been reported in patients receiving lithium concomitantly with diuretics and ACE inhibitors.

The administration of other potassium-sparing antihypertensives with NSAIDs has been shown to reduce the antihypertensive effect in some patients and result in severe hyperkalemia in patients with impaired renal function.
