Interação entre Furosemida e 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.

Angiotensin converting enzyme inhibitors or angiotensin II receptor blockers May lead to severe hypotension and deterioration in renal function, including renal failure.

Monitor for changes in blood pressure and renal function and interrupt or reduce the dosage of furosemide, angiotensin converting enzyme inhibitors, or angiotensin receptor blockers if needed.

Monitor for changes in blood pressure and adjust the dose of other antihypertensive drugs if needed.
